Question

Explain the structure of nucleus with the help of labelled diagram.

Answer 1

Nucleus:

• Nucleus is a spherical body that controls all the activities of the cell and hence they are called the brain of cells.
• Nucleus is surrounded by a double-layered membrane called nuclear membrane which consists of many pores known as nuclear pores.
• Nuclear membrane covers a jelly-like material called nucleoplasm.
• Nucleoplasm contains one or more spherical bodies called nucleoli and a network of thread-like material called chromatin.
• Chromatin contains genes that transfer from parent to offspring.
• During cell division, chromatin will condense and form chromosomes.
