Question

genetic material is contained within the ___ of the cell
cytoplasm
cell membrane
nucleus
ribosomes
this organelle is responsible for destroying worn - out cell parts:
golgi apparatus
ribosomes
mitochondrion
lysosomes
the ____ controls what enters and leaves the cell.
golgi apparatus
nucleus
cell membrane
mitochondrion

Explanation:

1. Genetic material (DNA) is located in the nucleus of a cell. The cytoplasm is the jelly - like substance outside the nucleus, the cell membrane is the outer - layer of the cell, and ribosomes are involved in protein synthesis.
2. Lysosomes contain enzymes that break down worn - out cell parts. The Golgi apparatus modifies and packages proteins, ribosomes make proteins, and mitochondria produce energy.
3. The cell membrane is a selectively permeable barrier that controls what enters and leaves the cell. The Golgi apparatus is for protein modification, the nucleus contains genetic material, and mitochondria are for energy production.

Answer:

1. C. Nucleus
2. D. Lysosomes
3. C. Cell membrane
