Prokaryotic & Eukaryotic Cells

The Cell Theory

1) The cell is the basis unit of life in all living things.

2) All cells come from existing cells.

3) All organisms are either multicellular or unicellular.

Prokaryotic Cell

1) They are unicellular organisms.

2) They lack membrane-bound structures (eg. the nucleus)

3) They tend to be small, simple cells, measuring around 0.1-5 hm (micro meter/s) in diameter.

4) They can be split into two domains, bacteria and archaea.

Prokaryotic Cell Features

Capsule, Cell Wall, Cell Membrane, Cytoplasm, Nucleoid, Ribosome, Flagella and Pili.

Eukaryotic Cell

1) They are both unicellular and multicellular organisms.

2) They contain membrane-bound structures (eg. the nucleus)

3) They tend to be large, complex cells, measuring around 10-100 hm (micro meters) in diameter.

4) They are plants, animals, fungi and protists.

Eukaryotic Cell Features

Cell Wall, Cell Membrane, Cytoplasm, Nucleus, Nucleolus, Mitochondria, Endoplasm Reticulum, Ribosomes, Vesicles and Vacuoles, Golgi Apparatus.
