The Cell Theory

The Cell Theory is composed of 3 ideas:

All living things are made up of one or more cells
Cells are the basic units of structure and function in an organism
All cells arise from existing cells.

Prokaryote and Eukaryote Cells

Prokaryote is a single-celled organism

They do not have a nucleus and membrane-bound organelles.

Prokaryote Cell

A eukaryote is an organism made up of one or more cells.
Some live as single-celled organisms
other are multicellular

Eukaryote Cell

​Animal cells only contain a cell membrane
Has specialized cells

Eukaryote - Animal

Plant cells contain both cell walls, cell membranes, and chloroplasts
Has specialized cells

Eukaryote - Plant
