Question

Seasonal changes bring about scenes like this one. Plant cells respond to changes in _________________ and as a result, photosynthesis slows and leaves change color. A) day length and available oxygen B) carbon dioxide and glucose levels C) light intensity and temperature change D) available oxygen and temperature change

Answer 1

C) light intensity and temperature change

Step-by-step explanation:

Plant leaves are green due to the presence of chlorophyll, a pigment responsible for trapping light and initiating photosynthesis. Photosynthesis slows as a result of lowered light intensity and temperature change. As chlorophyll production slows down, other plant pigments in the leaves become apparent and that gives us the autumn color.

Answer 2

C) light intensity and temperature change
