As the amount of daylight decreases in the fall and winter, processes such as cellular respiration slow down so plants can conserve energy. When this happens, what stage is the plant most likely entering?A.ProtectionB.PhotoperiodismC.Day-neutral periodD.Dormancy

During winter days, when trees look dead and cellular respiration continues very slowly, the trees are most likely in what stage?A.Day-neutral periodB.PhototropismC.Sheltering inD.DormancySUBMITarrow_backPREVIOUS

Timing of seasonal activities of plants in relation to change in environmental conditions is called

The diagram summarizes the steps of photosynthesis inside chloroplasts. If the plant cell the chloroplast is in does not receive enough sunlight, which event will happen first?A.An increase in the rate of the Calvin cycleB.A decrease in the rate of the Calvin cycleC.A decrease in the production of ATPD.An increase in the production of ATP

These steps need not take place one after the other immediately. For example, desert plants take up carbon dioxide at night and prepare an intermediate which is acted upon by the energy absorbed by the chlorophyll during the day.

Plants continually respire but photosynthesis requires sunlight. Explain how this produces a day-night cycle in the concentration of atmospheric CO2, seen in the video as a rapid pulsing.
