Nucleus

Hint

It is known as the 'site of protein synthesis in the cell', and synthesizes proteins. It is chiefly composed of RNA (Ribonucleic acid).

Nucleoplasm

It controls and coordinates all the activities and functions of the cell. It plays a vital role in cell division.

Chloroplast

Hint

It contains chromatin fibres, which are made up of DNA (Deoxyribonucleic acid). After cell division takes place, these chromatin fibres undergo certain structural changes, and are called chromosomes. These chromosomes carry the hereditary information of the genes.

Ribosome

It is a plastid, containing a pigment called chlorophyll. This chlorophyll captures energy from sunlight and helps in the manufacture of food by the process of photosynthesis.

Centrosome

It initiates and regulates cell division. It also helps in forming spindle fibres, with the help of asters.
