Plant cells produce oxygen in the process of photosynthesis at the cellular level. This causes plants at the organism level to perform which function?

Excretion or waste elimination

Explanation:

Photosynthesis is a metabolic process carried out by the cells of plant in order to synthesize their own food in form of sugar (glucose). The photosynthetic process combines carbondioxide (CO2), which enters through the STOMATA on their own leaves, and water (H2O) to produce glucose and oxygen gas.

Photosynthesis, which occurs in the Chloroplast organnelle of plant cells, gives off oxygen gas (O2) as a product. The oxygen, which serves as a waste product of photosynthesis, is released from the plant via the same STOMATA openings on their leaves.

The chemical equation is as follows:

6CO2 + 6H2O > C6H12O6 + 6O2

Hence, at the organism level (plant), the process of excretion or waste removal is carried out by the plant.

i think the answer would be d
