Cell Organelle: Nucleus
The nucleus is a circle in the middle of the cell.
It's membrane is called the nuclear membrane.
The purpose of the nucleus is to be the "control center" of the cell.
It contains DNA in it.
It also has the nucleolus inside it which synthesizes ribosomes which in turn synthesize proteins.
After the ribosomes are synthesized they leave the nucleolus most attach to the rough ER and some just float around in the cytoplasm.

Reflection: The nucleus might be the most important organelle in the cell as it controls all the cells functions. It holds DNA which is the basis for all living things so it is the reason the cell can even function.
Can you tell me what the nuclear membrane is made of?
ReplyDeleteThe nuclear membrane is made of a phospholipid bilayer. This means there's two layers of phospholipids with the heads toward the outside and the tails pointing inward.
DeleteDo the ribosomes stay in the nucleolus after the are created? If not, where do they go?
