Question

what is the main function of the mitochondria in a plant cell? to store waste in the cell to produce steroid hormones to break down sugar and release energy that the cell can use to package proteins and other substances and send them to different parts of the cell

Explanation:

Mitochondria are the power - houses of the cell. Through cellular respiration, they break down sugar (glucose) in the presence of oxygen to release energy in the form of ATP, which the cell can use. Storing waste is a function of vacuoles, producing steroid hormones is mainly related to smooth endoplasmic reticulum in some cells, and packaging and sending proteins is a function of the Golgi apparatus.

Answer:

to break down sugar and release energy that the cell can use
