Cells

The basic unit of all living organisms

Prokaryotic Cells

Cells without a nucleus

Eukaryotic Cells

Cells with a nucleus

Prokaryotes

Organisms made of prokaryotic cells

Eukaryotes

Organisms made of eukaryotic cells

Nucleus

Organelle that holds all genetic material (DNA) and controls cell activities

Cytoplasm

Jelly-like substance in cells containing nutrients

Cell Membrane

Semi-permeable layer controlling what enters and leaves the cell.

Mitochondria

Organelles containing enzymes for respiration to release energy for the cell.

Ribosomes

Small structures in the cytoplasm where proteins are produced.

Cell Wall

Structure made of cellulose in plant and bacterial cells that provides support and protection.

Vacuole

Plant cell structure holding cell sap (weak solution of sugars and salts) that keeps the cell swollen.

Chloroplasts

Organelles in plant cells containing chlorophyll for photosynthesis

DNA in Bacteria

Free in the cytoplasm as a main circular strand

Bacterial Cell Structures

Contain cell wall

Flagella

Hair-like structures on bacteria that help movement.
