What is the difference between prokaryotic and eukaryotic cells ?

Nucleolus

Assembly of ribosomes begin here

Nucleus

Control center of the cell. Contains DNA

Cell membrane

Forms a strong barrier between the cell and its surroundings. Regulates what enters and leaves the cell.

Nuclear membrane

Keeps nuclear contents separate and allows passage of materials into and out of the nucleus

Flagella

Longer- whiplike projections used for movement

Golgi Body (apparatus)

Modifies, sorts, and packages proteins from the E.R for storage or transport out of the cell

Eukaryotic cells

More complex. Contain a nucleus and other membrane bound organelles.

ER

Rough ER- assembly/transport of proteins Smooth ER-assembly/transport of lipids

Cilia

Short- hairlike projections used for movement

Cell wall

Supports and protects the cell as well as giving it shape

Prokaryotic cells

Very simple cells that do not contain a nucleus or other membeane bound organelles.

Mitochondria

Where cellular respiration takes place. Uses chemical energy stored in food to produce a compound called ATP.

Chloroplast

Where photosynthesis takes place & light energy from the sun in converted into chemical energy

Ribosomes

Where proteins are assembled. Use instructions coded in DNA to synthesize proteins
