Fewer students answered the essay version of this question correctly, compared with the multiple-choice version, indicating that they could correctly identify from a list the main contributors to plant mass gain, but could not articulate these ideas on their own. It should be noted that the multiple-choice version of the question appeared first on the exam forms, with the essay version occurring six questions later.

However, very few students used the wording of the multiple-choice distracters in their essay, suggesting little copying or transfer. Students who mentioned fertilizer or minerals, but indicated that these were minor contributors, were not counted as having heterogeneous responses. To determine how students interpreted the multiple-choice questions and to see whether their exam responses were indicative of their thinking, 14 student volunteers were interviewed about their midterm exam responses to two questions about the sources of mass when plants radish seeds and corn grow and the source of ATP for cellular work in Euglena.

Table 5. Excerpts from the interviews of the students who answered both questions about the sources of plant mass gain during growth correctly on the exam Burt in response to the radish seed stem: And then how this increase in mass biomass [radish seeds in light] occurred would obviously be not from water so it had to be from something else like some sort of glucose or something like that… It [glucose] is made of C6H12O6 and so it needs the CO2 to make for the carbon and it has water that uses H for the water from the water too. Devin in response to the radish seed stem: All right. With these, with the light and water, it's so much because during photosynthesis, carbon dioxide is taken in from the outside and then, through a number of processes, it's released.

But the carbon atoms add to the mass of the plants… Devin in response to the radish seed distracters: I know that plants need soil to grow in and that some of the minerals in soil help it to just grow and prosper and do its day-to-day activities, but it's not a significant contributor to the mass of the plant. I wouldn't say that this [solar radiation] is a direct contribution, but the plants need solar energy to do photosynthesis, so the solar radiation doesn't cause the increase in mass. That's not the materials, but it's like the light coming down is probably the cause of the… it makes the ATP that is needed for photosynthesis. Wendy in response to the radish seed stem: Okay, we spent like 20 minutes on this in class and so I can answer this without even thinking. The increase in biomass occurred from the intake of carbon dioxide and the expulsion of oxygen. Wendy in response to the stem of corn question: Oh that is easy, it is just because on farms, obviously they use fertilizers which are high in nitrates which can help to increase energy levels and bio mass intake because then they also have the intake from the roots, there is more minerals in the soil, increasing the bio mass, obviously there is carbon dioxide all around.

Wendy in response to the distracters for the corn question: It is still the CO2 because that is the main one, the others are just added bonuses to help with different processes because I want to say that there is a cycle. Olivia in response to the stem of the radish seed question: I just don't really remember, so I'm like, I know part of it and I understood … I got it when he was teaching it, but I haven't reviewed it, so I'm just not quite sure. I just know that there's something with carbons and that's why it has more mass… She chose carbon dioxide after seeing the distracters. Burt is the only student who frames his response in terms of tracing matter. Devin and Wendy give evidence of understanding the relative contributions of different sources with some inaccuracies or sloppy language. However, Wendy's opening sentence indicates that this might be a memorized response.

Table 6. Excerpts from the interviews of students who answered both questions about the sources of mass gain in plants during growth incorrectly on the exam. In the interview, Wren floundered for an answer in response to the radish seed question stem. She mentioned pyruvate oxidation, fermentation, Kreb cycle, Calvin cycle, and carbon dioxide release before mentioning that the mass gain came from glucose produced during photosynthesis. She explained her troubles by saying, Biology's just really hard for me, and I probably didn't study enough as I should have, but I just have a hard time memorizing like—trying to figure out what exactly I have to memorize for—like the carbon dioxide thing.

After seeing the distracters, she wavered between carbon dioxide and radiation, but chose radiation. When discussing the corn question, the interviewer asked her to rank the contributions of the many sources she named. She responded, Well, the last question was CO2, so we'll go with CO2 again on this one… And then I like the water followed by light, but that's very, very close… Together, because you have to have them both, but then I'd probably go with organic compounds and then minerals. When questioned about each of these choices, she wondered whether there was a formula for light, but then said that light is necessary but does not contribute to the biomass.

The interviewer asked whether CO2 and water were, like minerals, helpers or the actual material that becomes part of the plant. She responded, They're all kind of the helpers because carbon dioxide gets taken in and then it gets thrown off, and so does water. Ruth responded to the stem of the radish seed question saying, Okay, um all right, well I know that the light makes it grow which gives it like, nutrition, which it gets from the dirt and the water. And it takes in the nutrition into the, photosynthesis also adds to it [sounds unsure]. And it gives, I know it gives off CO2 and that releases off, but it doesn't really add to the weight… it gained in mass because it grew from the water and the soil and nutrition that it took up from the dirt through the water. She stuck to variations on this answer throughout the interview. Sherman did not come up with a response until after seeing the distracters for the radish seed question.

That was one of the big things I think that they were talking about. That's my guess. He did eventually choose carbon dioxide as the answer. Phillipa in response to the radish seed stem: I don't remember which one I chose. But the absorption of mineral substances coming through the roots… it makes sense, but… that it would absorb… it'd be heavier because of that, but I think it's more of the oxygen. After seeing the distracters, she changed oxygen to carbon dioxide, but eventually chose minerals. Winnona chose organic substances on the exam, but carbon dioxide in the interview. She explained her change in responses, I know, like if I were to retake this test, I would have definitely put that [inaudible].

But um… well um… I don't know. I just… I thought it through logically and I thought well it's absorbing stuff, organic substances. I thought, oh man, that has mass, you know, it's absorbing stuff that has mass. But I imagine that would have an effect, but it's not nearly as significant. I didn't think of photosynthesis… I didn't think it through, I don't think. Ivy in response to the radish seed stem: The source of the carbon is from carbon dioxide in the air—And that's how it—the plant fixes the carbon dioxide and releases the oxygen and uses that carbon to make sugars, or cellulose, or whatever they grow from. That's where the energy is coming from to create the mass. Ivy in response to the distracters of the corn question: Okay. Well, I would say A [minerals], still kind of a guess because I know it's necessary, but I wouldn't say that the most biomass comes from the absorption of the mineral substances.

Five of the 14 interviewees answered the question correctly on the exam and in the interview. Six said that Euglena use ATP made from sunlight both on the exam and in the interview. We thought that they might be interpreting the question to mean that sunlight is the ultimate source of energy for ATP synthesis, a correct statement. However, the interviews showed this not to be the case. Students indicated that ATP was a product of photosynthesis. Some mentioned the electron transport chain producing ATP in response to sunlight. Three students chose a response in the interview that differed from their exam choice. Before seeing the distracters in the interview, he could only articulate that Euglena use photosynthesis. After looking at the distracters, he wavered between that response and the correct answer. At first he was not sure that sugars were made in the chloroplast, and then he questioned whether they could leave the chloroplast.

Chapter 5: Introduction to Photosynthesis 5. It is easy to think of light as something that exists and allows living organisms, such as humans, to see, but light is a form of energy. Like all energy, light can travel, change form, and be harnessed to do work. In the case of photosynthesis, light energy is transformed into chemical energy, which autotrophs use to build carbohydrate molecules. However, autotrophs only use a specific component of sunlight Figure 5. Figure 5.

What Is Light Energy? The sun emits an enormous amount of electromagnetic radiation solar energy. Scientists can determine the amount of energy of a wave by measuring its wavelength, the distance between two consecutive, similar points in a series of waves, such as from crest to crest or trough to trough Figure 5. Visible light constitutes only one of many types of electromagnetic radiation emitted from the sun. The electromagnetic spectrum is the range of all possible wavelengths of radiation Figure 5. Each wavelength corresponds to a different amount of energy carried.

This radiation exists in different wavelengths, each of which has its own characteristic energy. Visible light is one type of energy emitted from the sun. Each type of electromagnetic radiation has a characteristic range of wavelengths. The longer the wavelength or the more stretched out it appears , the less energy is carried. Short, tight waves carry the most energy. This may seem illogical, but think of it in terms of a piece of moving rope. It takes little effort by a person to move a rope in long, wide waves. To make a rope move in short, tight waves, a person would need to apply significantly more energy. The sun emits a broad range of electromagnetic radiation, including X-rays and ultraviolet UV rays.

The higher-energy waves are dangerous to living things; for example, X-rays and UV rays can be harmful to humans. Absorption of Light Light energy enters the process of photosynthesis when pigments absorb the light. In plants, pigment molecules absorb only visible light for photosynthesis. The visible light seen by humans as white light actually exists in a rainbow of colors. Certain objects, such as a prism or a drop of water, disperse white light to reveal these colors to the human eye. The visible light portion of the electromagnetic spectrum is perceived by the human eye as a rainbow of colors, with violet and blue having shorter wavelengths and, therefore, higher energy. At the other end of the spectrum toward red, the wavelengths are longer and have lower energy.

Photosynthesis Problem Set 1

Understanding Pigments Different kinds of pigments exist, and each absorbs only certain wavelengths colors of visible light. Pigments reflect the color of the wavelengths that they cannot absorb. All photosynthetic organisms contain a pigment called chlorophyll a, which humans see as the common green color associated with plants. Chlorophyll a absorbs wavelengths from either end of the visible spectrum blue and red , but not from green. Because green is reflected, chlorophyll appears green. Other pigment types include chlorophyll b which absorbs blue and red-orange light and the carotenoids. Each type of pigment can be identified by the specific pattern of wavelengths it absorbs from visible light, which is its absorption spectrum. Many photosynthetic organisms have a mixture of pigments; between them, the organism can absorb energy from a wider range of visible-light wavelengths. Not all photosynthetic organisms have full access to sunlight.

Some organisms grow underwater where light intensity decreases with depth, and certain wavelengths are absorbed by the water. Other organisms grow in competition for light. Plants on the rainforest floor must be able to absorb any bit of light that comes through, because the taller trees block most of the sunlight Figure 5. Each pigment can absorb different wavelengths of light, which allows the plant to absorb any light that passes through the taller trees. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules.

The light-dependent reactions begin in a grouping of pigment molecules and proteins called a photosystem. Photosystems exist in the membranes of thylakoids. A photon of light energy travels until it reaches a molecule of chlorophyll. To replace the electron in the chlorophyll, a molecule of water is split. Technically, each breaking of a water molecule releases a pair of electrons, and therefore can replace two donated electrons.
