3. What is unicellular organism?
4. What is multicellular organism?

1.
Robert Hooke.
2.
Cell is the basic structure for a living organism it if fully alive and
performs all the important functions to keep an organism alive.
3.
Single celled organism (or) the organism which has only one cell which
performs all the body functions
4.
Organism with many cells or more than one cell are called multicellular all
the cells perform certain functions together to keep the organism alive.
5.
Unicellular has one cell and multicellular has many cells that performs the
body functions. E.g. paramecium, euglena and humans, fish
