Question

1. where are the ribosomes usually located in plant and animal cells? a. inside the nucleus b. near the cell membrane c. on the endoplasmic reticulum d. inside the vacuole

Explanation:

Ribosomes are organelles involved in protein synthesis. In plant and animal cells, ribosomes can be found free - floating in the cytoplasm or attached to the endoplasmic reticulum (forming rough endoplasmic reticulum). The nucleus contains genetic material (DNA), the cell membrane is a protective layer around the cell, and vacuoles are storage organelles.

Answer:

C. On the endoplasmic reticulum
