Question

describe the different parts of a nucleus and cell wall​

Answer 1

Answer:

Hi friends

Explanation:

The important parts of a plant cell are:-

1) Cell wall is a rigid organelle composed of cellulose.

It lies outside the cell membrane.

It gives shape to the plant cell and also protects the cell.

2) Plama membrane or cell membrane is a bilipid layer.

It separates the cell from its external environment.

It is selectively permeable and also protects the cell and provides stability.

3) Cytoplasm is a jelly-like substance composed of water.

It is found between the cell membrane and nucleus.

All the organelles are present here.

Eg- Endoplasmic reticulum, golgi apparatus, plastids (speciifc to plant cells), mitochondria, lysosomes etc.

4) Nucleus is the largest organelle in the cell.

It is surrounded by a double membrane called the nuclear envelope.

The genetic materials DNA is present here on special strands called chromosomes.

It is called the control center of the cell (for cell metabolism and reproduction).

hope this helps you

Answer 2

Answer:

Answer :

Nucleus

The nucleus consists of the following main parts:

• $\twoheadrightarrow$ (1) Nucleolemma or nuclear membrane (karyotheca)
• $\twoheadrightarrow$ (2) Nuclear sap or karyolymph or nucleoplasm
• $\twoheadrightarrow$ (3) Chromatin network or fibres
• $\twoheadrightarrow$ (4) Nucleolus (5) Endosomes.
