The stomata in plants' leaves open and close depending on external and internal conditions. Which of the following would most likely cause the stomata to close?A.The plant is taking in too much water from the soil.B.The plant needs additional carbon dioxide for photosynthesis.C.The plant is losing too much water from transpiration.D.The plant needs additional sunlight for photosynthesis.

Heavy dust can cause:  A. Leaf blights  B. Opening of stomata  C. Closure of stomata  D. Brewing of leaves

Stomata remain closed in desert plants during day time. How dothey perform photosynthesis?

A plant wilted but later recovered. The stoma represents cells of the plant during recovery. As the plant recovered, the rate of photosynthesis increased becauseAthe stomatal pore opened, allowing carbon dioxide to enter the leaf.Bthe wilting prevented the entry of water into the leaves.Cchlorophyll within the leaf now had access to O2 gas.Dthe temperature of the leaf was reduced.

What happens when stomata open?Question 4Select one:a.Water vapor is lost to the external environment, increasing the rate of transpiration.b.Water vapor is lost to the external environment, decreasing the rate of transpiration.c.Water vapor enters the spaces in the mesophyll, increasing the rate of transpiration.d.Water vapor enters the spaces in the mesophyll, increasing the rate of transpiration.

What are the functions of stomata and guard cells, and what would happen to a plant if these cells did not function correctly?Group of answer choicesStomata allow gases to enter and exit the plant. Guard cells regulate the opening and closing of stomata. Photosynthesis and, in turn, transpiration, would not occur which is necessary to maintain a continuous flow of water upwards from the roots to the leaves.Guard cells allow carbon dioxide to enter and exit the plant. Stomata regulate the opening and closing of guard cells. Transpiration and in turn, photosynthesis would not occur which is necessary to maintain a continuous flow of water upwards from the roots to the leaves.Stomata allow oxygen to enter and exit the plant. Guard cells regulate the opening and closing of stomata. If the cells didn’t function, photosynthesis would continue but transpiration would cease, which would interfere with the necessary continuous flow of water upward from roots to leaves.Guard cells allow carbon dioxide to enter and exit the plant. Stomata regulate the opening and closing of guard cells. If the cells didn’t function, photosynthesis and transpiration would cease, which would interfere with the necessary continuous flow of water upward from roots to leaves.
