What happens if these plants open their stomata during the
day?
Answer:
These plants are xerophytes. If they open the stomat during the day, transpiration takes place where water will be evaporated through the stomata.
Evaporation of water in the form of vapours through stomata is called transpiration.
Desert plants absorb CO2 at night (stomata are closed during the day to prevent water from leaving the plant). CO2 is converted into malate, which is stored in vacuoles until morning. Why would plants not be able to directly store CO2 inside of vacuoles?
How does this minimize water loss by such plants? How does this minimize water loss by such plants? A. CAM plants are able to fix CO2 and accumulate carbon in the form of organic acids during the night, when the loss of water through open stomata thereby is minimized. During the day, when solar energy is available but the potential for water loss is highest, CAM plants close their stomata and channel carbon from malate into the Calvin cycle. B....
at nights, plants close their stomata and do not photosynthesize or transpire. nonetheless, there are still sucrose sources and sinks in the plant body and bulk flow of phloem sap occurs. under such conditions, explain what happens to water in the xylem ?

Stomata are pores on the surfaces of the leaves and stems of plants that regulate gas exchange between the plants and the atmosphere. Researchers found that the stomata density on the leaves of a species of plant change as the concentration of CO2CO2 in the atmosphere changes. When grown at 350 ppmppm CO2CO2 the plant has an average density of 300 stomata per mm2mm2, but when grown at 400 ppmppm CO2CO2 the plant has an average density of 250 stomata...
For lower and higher plants do you know what groups have stomata, vascular tissues, seeds, heterospory or homospory, flowers? Do you know the flower parts, what nurses the embryo, what are the gametophytes in angiosperms?
PUULIUI The stomata epidermal cells of monocotyledons plants are straight and in parallel lines True False
CAM plants keep stomata closed in the daytime, thus reducing loss of water. They can do this because they Ofix CO2 into pyruvate in the mesophyll cells Ofix CO2 into sugars in the bundle sheath cells use photosystem I and photosystem II at night fix CO2 into organic acids during the night
Describe why high temperature increases photorespiration in C3 plants (Hint: your answer should involve stomata and carbon dioxide). How do C4 plants avoid photorespiration?
