Question

Brainliest answer for corrct answer

What is the outcome of the release of carbon particles and smoke from factories?
a. Increases the rate of respiration in plants.
b. Decreases the rate of photosynthesis in plants.
c. Increases the absorption of carbon dioxide by plants.
d. Decreases the rate of transpiration in plants.

Answer 1

Answer:

Atmospheric pollutants like carbon particles and smoke from factories have a negative effect on the plants. They can have direct toxic effects, or indirectly by changing soil pH followed by solubilization of toxic salts of metals like aluminium. The particulate matters have a negative mechanical effect. They cover the leaf blade reducing light penetration and blocking the opening of stomata. These impediments influence the process of photosynthesis whose rate declines sharply.

Option B is correct.
