Question

Write short note on
(i) cytoplasm
(ü) Nucleus of a cell
​

Answer 1

Answer:

Cytoplasm - Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus.

All prokaryote and eukaryote cells also have cytoplasm (or cytosol), a semiliquid substance that composes the volume of a cell. Essentially, cytoplasm is the gel-like material enclosed by the plasma membrane.

Cytoplasm is the gelatinous liquid that fills the inside of a cell. It is composed of water, salts, and various organic molecules. Some intracellular organelles, such the nucleus and mitochondria, are enclosed by membranes that separate them from the cytoplasm.

Nucleus of a cell - The nucleus is the information centre of the cell and is surrounded by a nuclear membrane in all eukaryotic... A cell normally contains only one nucleus. Under some conditions, however, the nucleus divides but the cytoplasm does not.

The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.

Hope this helps!

Answer 2

Question

Write short note on:-

(i) Cytoplasm

(ii) Nucleus of a cell

Answer

(i) Cytoplasm:-

It is a fluid that fills the cell and occurs between the plasma membrane and the nucleus. Cell organelles such as mitochondria, ribosomes, Golgi bodies, etc. are suspended in the cytoplasm. The cytoplasm helps in the exchange of materials between cell organelles.

(ii) Nucleus of a cell:-

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.
