Answer:

a) If the electron transport protein is disrupted in the chloroplast then ATP production will not occur. ATP is required for the light-independent process like in the calving cycle by which carbohydrate production takes place. Therefore disruption in electron transport chain will reduce the production of carbohydrates and cellular respiration will also decrease.

b) The effect will be not good on the individual plant because ATP is important for the cell to grow and remain metabolically active and fit. Therefore this virus will hinder the growth and repairability of plant and would weaken the plant.

The ecosystem that comprises savannas, grasslands and shrublands are called the prairies. This type of community lacks tress and tall plantations and are mainly dominated by sedges and grasses.

(a) The cellular process will get affected as the virus will inhibit reactions of photosynthesis in the chloroplast. If the mutation occurs then the ETC will be disrupted.

Electrons would not be able to transport through the ETC efficiently creating an ineffective H+ gradient, resulting in less ATP and NADPH production. Thus, the virus will decrease the production of products of cellular respiration.

(b) The effects on individual plants will be the inability to photosynthesis, repair tissues and grow.

The deficiency of ATP and NADPH in the cells will affect the Calvin cycle and plants will not be able to produce food (glucose) and oxygen. This inability of plants will result in plant deaths.
