- What are the flaws/is wrong ? n photosynthesis, a plant captures light energy and uses it to transform hydrogen and carbon dioxide into glucose and nitrogen. Photosynthesis occurs inside of a chloroplast. A chloroplast is a double membrane bound organelle that is filled with stroma and has stacks of thylakoid disks called grana. Chlorophyll is the pigment in chloroplasts that allow it to capture light and it absorbs all light except green light. Photosynthesis has two main reactions: the light reactions and the Calvin cycle. The light reactions occur in the stroma. Light is captured by photosystem II and is used to split water into hydrogen and oxygen. This release of energy is passed to the electron transport chain to produce ATP. The remaining energy is passed and more light is captured by photosystem I and is used to make NADPH. The ATP and NADPH move into the thylakoid disks and is used in the Calvin cycle. The Calvin cycle has three stages. In carbon fixation, the enzyme RuBisCO…10. Observe the graph on the right. If you had a hypothetical plant that only had a hypothetical photopigment with an absorption maximum at 585, which color light would produce the highest rate of photosynthesis? ltra Violet Blue 456-492 nm Green 492677 nm Yellow Orange 597-620 nm Red intra vielet red 400-455 nm 677-697 nm 620-700 nm nm 400 500 600 700 short wtength Ieng vetength high fmuency lawhumcy1. Look at the molecular formula for plant tissue. Where does the carbon come from? 2. Where does the hydrogen in C6H12O6 come from? 3. When radioactive isotopes of oxygen atoms are put into CO2 molecules and the plant is allowed to photosynthesize, only new plant tissue (C6H12O6) is radioactive and the oxygen gas given off is not radioactive. Draw a dotted line in the photosynthesis equation to show where the oxygen atoms in CO2 go. 4. Draw a dotted line in the equation to show where the oxygen atoms in H20 go.

A single stoma is surrounded by two guard cells that change shape in response to environmental factors and open or close the stoma. Which of the following best explains how the structure of the leaf is used in processes that occur in the plant? * Water enters the plant through the surface of the leaf for transpiration. O Gases for photosynthesis are exchanged through the surface of the leaf. O Micronutrients are taken in through the microscopic stoma O Energy for cellular reproduction is absorbed through the surface of the leaf.
