Question

identify the functions of the labeled structures. nucleus controls what enters and leaves the cell directs cell activity breaks down waste material and debris complete ribosomes break down sugar for energy produce proteins for the cell package and distribute proteins done

Explanation:

The nucleus contains the cell's genetic material (DNA) which directs all cell activities such as growth, metabolism, and reproduction. Ribosomes are the sites of protein synthesis. They read the genetic code (from mRNA) and assemble amino acids into proteins that are essential for the cell's structure and function.

Answer:

Nucleus: directs cell activity; Ribosomes: produce proteins for the cell.
