Question

Explain: Cell membrane, Cytoplasm, cell wall and Nucleolus.​

Answer 1

Explanation:

Basic Definitions: Cell Membrane = the semi-permeable structure that surrounds the cell and keeps all of the cells organelles from exploding everywhere. Cell Wall = the rigid 'armor' of the cell that surrounds it after the membrane. ... Nucleus = A really dense organelle of the cell usually surrounded by two membranes

Answer 2

Answer:

1. Cell membrane - The cell membrane is a biological membrane that separates the interior of all cells from the outside environment which protects the cell from its environment. The cell membrane consists of a lipid bilayer, including cholesterols that sit between phospholipids to maintain their fluidity at various temperatures.

2. Cytoplasm-The cytoplasm (also known as cytosol) is the protoplasm of a cell outside the cell nucleus. It is the jelly-like material plus the organelles outside the nucleus, and inside the cell membrane. ... It includes dissolved molecules, and water that fills much of the cell.

3. Cell Wall- The cell wall is the protective, semi-permeable outer layer of a plant cell. A major function of the cell wall is to give the cell strength and structure, and to filter molecules that pass in and out of the cell.

4. Nucleolus- ​The nucleolus is considered as the brain of the nucleus. It occupies around 25% of the volume of the nucleus. It is mainly involved in the production of subunits which then together form ribosomes. Therefore, nucleolus plays an important role in protein synthesis and the production of ribosomes in eukaryotic cells.
