ANSWER CHOICES ARE IN THE PHOTO. thanksThese 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. ScleridsPhotorespiration causes a number of impacts on a plant. Which of these drives the ECOLOGICAL difference between C3 and C4 plants Question 4 options: Rubisco mistakes Oxygen for CO2 The plant uses energy to convert the toxic product of photorespiration back into something less harmful The plant needs a large number of enzymes to be able to regain the energy invested in the 2 carbon molecule produced by photorespiration None of these explain the difference The plant needs to do gas exchange to remove oxygen and add CO2 to the cell doing photosynthesis to avoid photorespiration.
- 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 ReadinPlant 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..Rubisco can bind with CO2 or 02. When it binds with O2, it "wastes" some of the energy captured from the sun. This reaction is photorespiration and is favored at high temperatures and low CO2:02 ratios. Which of the following strategies should limit photorespiration (select all that apply). Keep stomata closed. Keep stomata open. Physically separate the light and light-independent reactions. Temporally separate CO2 uptake and fixation.

A. YES! This is a great example of thermodynam OB. YES! Since CO₂ will move rapidly from mitochondria to the chloroplast. C. NO! To grow, the cell must fix more CO₂ than it releases through respiration. OD. NO! Most plant cells do not photosynthesize and respire at the same time. Reset Selection V Reset Selection Question 4 of 5 One characteristic of enzyme competitive inhibition is that it results in an increase in the Km of the enzyme without a change in the Vmax Why does competitive inhibition cause an increase in Km? A. Because by binding to the active site the inhibitor increases the affinity of the enzyme for substrate. B. Because at low substrate concentration the inhibitor interferes with substrate binding to the enzyme. C. Because the inhibitor binds to substrate molecules preventing them from accessing the enzyme active site. D. Because the inhibitor changes the shape of the active site preventing substate binding. 30³ F2 3 Question 5 of 5…Choose the best answer for following question. C4 photosynthesisa. is the same as C3 photosynthesis, because it takes place inchloroplasts.b. occurs in plants whose bundle sheath cells contain chloroplasts.c. takes place in plants such as wheat, rice, and oats.d. is an advantage when the weather is hot and dry.e. Both b and d are correct.
- If a plant was deprived of glucose, what would happen? Group of answer choices a-It would make its own glucose and be perfectly healthy. b-It would perform alcoholic fermentation instead of respiration. c-Its chloroplasts would no longer function correctly. d-It would perform lactic acid fermentation instead of respiration. Photosynthesis would stop occurring, causing the leaves to change color.What is the difference between the way C3 and C4 plants fix CO2 from the atmosphere? Question 4 options: C3 plants fix CO2 and conduct the light-dependent reactions in the same cells; C4 plants conduct these activities in different cells. C4 plants fix CO2 and conduct the light-dependent reactions in the same cells; C3 plants conduct these activities in different cells. C3 plants fix CO2 and conduct the light-dependent reactions at the same time of day; C4 plants conduct these activities at different times of the day.
