b. stroma
c. outer membrane
d. mesophyll
Step by step
Solved in 4 steps
- In which compartment of the plant cell do the lightindependentreactions of photosynthesis take place?a. thylakoidb. stromac. outer membraned. mesophyllPlant is autotroph which means it can make its own nutrients by photosynthesis. a. Define photosynthesis. b. Photosynthesis takes place in the mesophyll cells. Name the cells, then complete the table below. Cell Name Shape and Arrangement Function c. Other than from photosynthesis, plant can get nutrients from the soil. Name 4 minerals that the plant gets from the soil, then state the functions. d. With reference to diffusion, osmosis, and active transport, explain how the root hair cell absorbs water and mineral ions from the soil. Water... Mineral ions..What is the name of the cellular structure where the light-dependent reactions of photosynthesis occur in plants? Stroma Thylakoid membrane Outer chloroplast membrane Stomata
- Opening and closing of pores is a function performed by: I. Stomata II. Chlorophyll III. Chloroplast IV. Guard cellsWhat is the BEST explanation for why thylakoid membranes are flat and stacked? A. to fit more into a chloroplast B. to increase surface area for light absorption and cross- membrane traffic C. to increase the color of the leaf as camouflage from herbivores D. to hold more ATPWhere in plant cells does the Calvin cycle take place? a. thylakoid membrane b. thylakoid space c. stroma d. granum
- These plant cells have only primary cell walls and are important as the site of photosynthesis: Select one: O a. Collenchyma Ob. Sclerenchyma O c. Parenchyma d. Fibers e. ScleridsMain site of photosynthesis: I. Leaf II. Stem III. Chloroplast IV. Guard cellsPhotosynthesis occurs in the chloroplasts packed within the mesophyll cells. Summer leaves are green because they contain about 50 times more chlorophyll than carotenoids. But during the fall, carotenoids have their season of glory because chlorophyll breaks down first, revealing the striking orange and yellow colors of carotenoids, which were there all along. The changes that leaves undergo before they fall off allow the plant to reclaim nutrients from the leaves for storage and use the following spring. How do these nutrients leave the leaf ?
- In hot, dry climates, plants have evolved mechanisms to avoid photorespiration. Which of the following is FALSE Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a b с d C3 plants have no mechanism to avoid photorespiration C4 plants reduce photorespiration by separating the light reaction in the mesophyll cells from the light- independent reaction in the bundle-sheath cells CAM plants minimize photorespiration by collecting and storing CO2 at night and keeping their stomata closed during the day C4 plants include corn, sugarcane, and many grasses CAM plants can undergo photophosphorylation in the absence of sunlight 7 Open in ReadinConsider the relationship between temperature and photosynthesis. As temperatures increase,gases such as CO2 diffuse faster. As a result, plant leaves will lose CO2 at a faster rate thannormal. If the amount of light reaching the leaf and the amount of water available are adequate,predict how this loss of gas will affect photosynthesis in the leaf.Which process is most directly driven by light energy? A. creation of a pH gradient by pumping protons across the thylakoidmembraneB. removal of electrons from chlorophyll moleculesC. reduction of NADP+ moleculesD. carbon fixation in the stroma
