3. Three basic components of the cell are Nucleus, Cell membrane and Cytoplasm.

Nucleus:

1. The nucleus is a double membrane-bound organelle located at the center of a cell.
2. The nucleus regulates the growth and metabolic activities of a cell
3. It contains DNA and also controls the replication and transcription of DNA.

Cell membrane:

1. The cell membrane is made up of lipid bilayers.
2. It provides a fixed environment inside the cell.
3. The cell membrane is selectively permeable to certain molecules and regulates the transport of molecules in and out of the cell

Cytoplasm:

1. Cytoplasm lies between cell membrane and nucleus.
2. It is a semi-fluid matrix where cellular activities take place.
3. The cell organelles such as mitochondria, endoplasmic reticulum, vacuoles, Golgi apparatus, etc. are suspended in the cytoplasm.
