Identify the principal role of cellular respiration. to convert solar energy into the chemical energy of sugars to convert the chemical energy of sugars into heat to maintain an elevated body temperature to convert kinetic energy into the chemical energy of sugars to convert the chemical energy of sugars into the chemical energy that fuels life's processes

A. To convert the chemical energy of sugars into the chemical energy that fuels life's processes

Explanation:

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
