DISCOVEry

Cells were discovered by Robert Hooke in 1665 using a compound microscope that he designed.

There are millions of types of cells

Muscle Cells

Fat cells

Fungal cells

Red blood cells

Hair cells

Yeast cells

White blood cells

Egg cells

Algal cells

Nerve cells

Sperm cells

Rod cells

Cone cells

Bacterial cells

and so many more

Cells come in many shapes and sizes

two main types of Cells

Prokaryotic

Eukaryotic

Question 1

Cell Theory

Question 2

All Cells come from other cells.

All organisms are composed of cells.

Cells are alive and the basic living units of organization in all organisms.

What is in a Cell?

Cell Parts # 3 - 6

Nucleus is found in Eukaryotes and stores/protects DNA

Animal Cellcovered by a cell membrane that allows thing to enter cell

Plant Cell Plants contain a cell wall, chloroplast and Large Vacuole

Cell WallHelps with structure and protection
