[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
|
|
Plant cannot absorb water and oxygen from the air which would dry out the plant
|
|
|
Plant cannot exchange oxygen for carbon dioxide which would decrease photosynthesis
|
|
|
Glucose made in photosynthesis cannot get to the rest of the plant which would starve the plant
|
|
|
Sunlight cannot reach the plant’s tissues which would limit photosynthesis
|
Detailed explanation-1: -What will happen if green plants stop taking in carbon dioxide & release oxygen? If the green plants stopped taking carbon dioxide, they will die and the human beings and animals would not get oxygen and would die too.
Detailed explanation-2: -If the temperature decreases, the rate of photosynthesis will decrease as enzyme activity slows. If the temperature increases, the rate of photosynthesis increases. If the temperature is too high, enzymes will denature, causing photosynthesis to slow drastically.
Detailed explanation-3: -If stomata are choked due to dust, gaseous diffusion through stomata will get hampered. Plants will not get sufficient carbon dioxide, nor oxygen produced during photosynthesis can escape out.
Detailed explanation-4: -Stomata are the pores on the plant skin. They help in the exchange of carbon dioxide and oxygen. Guard cells help stomata to open and close. Also, plant closes stomata when it does not need carbon dioxide for photosynthesis to prevent water loss.
