Agreen plant receives more sunlight than usual. which part of the plant cell would be most directly affected by this change? a. cell wall b. mitochondria c. chloroplasts d. dna

The correct answer will be option C (Chloroplasts).

Explanation:

Chloroplasts are the cell organelles which contains pigment which can absorb light from the sun and use it to make food.

Though light acts as a substrate for photosynthetic energy conversion, too much of light can harm plants as too much light damage and degrade the reaction center of PS II (water-splitting photosystem) in the chlorophyll.

It produces highly oxidizing radicals and toxic reactive oxygen species (ROS) which can damage the cell.

So, plant shows movement of chloroplast in response to high light as an adaptive mechanism by accumulating along the walls in parallel orientation to the incident light.

Thus, option C (Chloroplasts) is the correct answer.

answer: the blood-brain barrier is a layer of specialized membranes and cell processes designed to keep undesirable substances from passing from the bloodstream into the precious tissues of the brain. while the blood-brain barrier does keep most bad things out of the central nervous system, it is not impermeable.
