Question

what is the main function of the lysosome in an animal cell?
to control which substances enter and leave the cell
to contain the information that the cell uses for growth and activities
to break down waste and worn - out cell parts
to direct cell activities by sending instructions to different parts of the cell

Explanation:

Lysosomes in animal cells are known as the "digestive system" of the cell. They contain hydrolytic enzymes that break down waste materials, worn - out cell parts, and even foreign invaders. The option "to break down waste and worn - out cell parts" matches this function. The option "to control which substances enter and leave the cell" is the function of the cell membrane. The option "to contain the information that the cell uses for growth and activities" is the function of the nucleus. The option "to direct cell activities by sending instructions to different parts of the cell" is related to the nucleus or other regulatory structures, not lysosomes.

Answer:

to break down waste and worn - out cell parts
