Cell Theory

Cell Theory is a fundamental concept in biology that states: 1) All living organisms are composed of one or more cells. 2) The cell is the basic unit of structure and organization in organisms. 3) All cells come from pre-existing cells.

Cells are considered the building blocks of life because they are the smallest unit of living matter and make up all living organisms.

A prokaryotic cell is a type of cell that does not have a nucleus or other membrane-bound organelles. Examples include bacteria.

A eukaryotic cell is a type of cell that has a nucleus and membrane-bound organelles. Examples include plant and animal cells.

Robert Hooke was a scientist who is credited with the discovery of cells. He coined the term 'cell' after observing cork under a microscope.

Anton Van Leeuwenhoek is known for his work in microscopy and was the first to observe living cells, which he called 'animalcules'.

The basic unit of life is the cell.

It means that new cells are produced by the division of existing cells, rather than arising spontaneously.

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and organelles.

Cell membranes protect the cell and regulate what enters and exits, maintaining homeostasis.
