Question

(a) Why could cells not be observed and studied for thousands of years ?
(b) State the cell theory of organisms.

Answer 1

a-Cells could not be observed thousands of years ago because there was no technology advanced enough to view microscopic organisms.

b-
The cell theory states that the cell is the basic unit of life and that all other cells are developed from an existing cell.

This theory was developed way back in the mid of 17th century.

This theory later became the foundation of biology.

This was made possible by the advancing technology.
