Question

A mass located in the cytoplasm of a cell, separated from the cytoplasm by a nuclear

membrane; considered the control center of the cell.
A.mitochondria
B.nucleolus
C.pinocytic vesicle
D.nucleus

Answer 1

D

Step-by-step explanation:

Nucleus contains all the genetic material that codes for different proteins that control the cell's actions. It's surrounded by a nuclear membrane.

However,

• Mitochondria is used for energy production and isn't surrounded by a nuclear membrane. It's in fact surrounded by 2 membranes.

• Pinocytic vesicles usually contain endocytosed material from outside that has nothing to do with the cell's control.

• Nucleolus is inside the nucleus and is used to make rRNA needed for ribosomes production. A nucleolus is not surrounded by any membrane.
