Textbook Question
Chapter 30, Problem 2CT
Photosynthesis sustains plant growth, and inputs of sunlight sustain photosynthesis. Why, then, do seedlings that germinate in a fully darkened room grow taller than seedlings or the same species that germinate in full sun?

Photosynthesis 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 ?
What are the products of the light-dependent reactions of photosynthesis?
1) production of ATP, oxygen, and NADPH
O 2) production of ATP, water, and NADH
3)
regeneration of NAD+
O 4) Production of G3P and ATP
O 5) production of oxygen and NAD+
Photosynthesis ceases when leaves wilt, mainly because(A) the chlorophyll in wilting leaves is degraded.(B) accumulation of CO2 in the leaf inhibits enzymes.(C) stomata close, preventing CO2 from entering the leaf.(D) photolysis, the water-splitting step of photosynthesis,cannot occur when there is a water deficiency.

A) roots of a plant following water B) plant bending toward the light C) roots growing into the soil D) a venus flytrap capturing a flyarrow_forwardWhat is the major trade-off plants face when they undergo photosynthesis? When they open their stomata to let in oxygen, they can lose water. When they open their stomata to release oxygen, they can lose water. When they open their stomata to let in carbon dioxide, they can lose water. When they open their stomata to let in water, they can lose carbon dioxide.arrow_forwardHow do C4 plants minimize photorespiration? Multiple Choice Stomata are only opened at night, storing carbon dioxide in the stroma. During the day, the carbon dioxide is released for photosynthesis. Carbon dioxide is fixed twice in different cells. The Calvin cycle occurs in the bundle sheath cells where oxygen concentrations are lower. Carbon dioxide is fixed twice in different cells so that carbon dioxide does not come into contact with rubisco. Stomata are only opened at night, storing oxygen in malate. During the day, the oxygen is released for photosynthesis. Stomata are only opened at night, storing carbon dioxide in malate. During the day, the carbon dioxide is released for photosynthesis.arrow_forward
- Closed stomata ________. a. limit gas exchange b. permit water loss c. prevent photosynthesis d. absorb lightarrow_forwardThere is a trade-off between photosynthesis and transpiration in leaves because (a) numerous stomatal pores provide both gas exchange for photosynthesis and openings through which water vapor escapes (b) a waxy layer, the cuticle, reduces water loss (c) blue light triggers an influx of potassium ions (K+) into the guard cells (d) leaves of deciduous plants abscise as winter approaches in temperate climates (e) stomata are closed at night, although water continues to move into the roots by osmosisarrow_forwardJaden grows geraniums in his greenhouse. He has noticed that his flowers are not growing very well. The greenhouse is in the shade for much of the day and maintains a temperature of 23°C (74°F).

Oxygen gas is produced in the thylakoid lumen by the oxidation of water by photosystem I. Ferrodoxin and NADP+ reductase participates in the reduction of NADP+ to NADPH. Carbon dioxide enters the plants via stomata. Rubisco attaches three molecules of ribulose bisphosphate (RuBP) to one molecule of carbon dioxide.arrow_forwardIf a C3 plant that normally closes its stomata during hot, dry conditions were triggered to open them instead, the most likely outcome would be that O water leaves the leaf, decreasing the rate of photosynthesis O glucose leaves the leaf, increasing the rate of photosynthesis O CO₂ enters the leaf, decreasing the rate of photosynthesis O O₂ enters the leaf, increasing the rate of photosynthesis more chlorophyll is made, increasing the rate of photosynthesisarrow_forward
