Question

Cell is the basic unit of life. Discuss it in brief.

Answer 1

Hint: These are also called the building blocks of life. These were discovered by Robert Hooke in the year 1665. The cells consist of cytoplasm which contains proteins and nucleic acids and the cytoplasm is enclosed within a membrane.

Correct step by step answer:
The cell is not only the basic unit of life but it is mainly the basic structural and functional unit of life because all known organisms are made up of cells and all the functions of the body take place within the cell. This means all the biochemical processes required to live can be performed by the cells.
For the survival of all living organisms, the basic needs are the same. All living organisms need to respire, digest food for obtaining energy, and get rid of metabolic cells that are capable of performing all the metabolic functions of the body.
These are also called the building blocks of life and the study of cells is called cell biology or cellular Biology or cytology.
Based on the number of cells present within the body of an organism, the organisms are divided into two groups
1) unicellular organisms: These are single-cell organisms such as bacteria.
2) multicellular organisms: these organisms are made up of more than two cells. These include plants as well as animals.

Note: Cells are basically of two types: the eukaryotic cell and the prokaryotic cell. The prokaryotic cells are generally single-celled organisms. The nucleus is absent in prokaryotic cells and these cells are smaller and simpler than eukaryotic cells. In the eukaryotic cell, the nucleus is covered with a double membrane.
