Question

a plant with a mutation that reduces the number of chloroplasts in its leaf cells would most directly impact which of the following processes?
water absorption by the roots
gas exchange through the stomata
the rate of photosynthesis
the transport of sugars throughout the plant
during photosynthesis, where does the oxygen that is released into the atmosphere originate?
from the carbon dioxide molecules
from the breakdown of glucose
from the chlorophyll pigment
from the splitting of water molecules

Explanation:

Chloroplasts are the sites of photosynthesis in plant cells. Fewer chloroplasts would directly reduce the rate of photosynthesis. In photosynthesis, water is split during the light - dependent reactions, and oxygen is released as a by - product.

Answer:

1. The rate of photosynthesis
2. From the splitting of water molecules
