Cells Part 2 (Module 2)

Ribosomes

Protein synthesis

Attached to endoplasmic reticulum

Endoplasmic Reticulum

Circulates materials in ctyoplasm

Stores enzymes and other proteins

Rough ER

Site for the attachment of ribosomes

Important in protein synthesis

Smoot ER

No ribosomes

Sites for production of lipids and detoxification of organic molecules

Golgi Apparatus

Bound cisternae

Sorts, packages, and secretes proteins and lipids

Lysosomes

Contains hydrolytic enzyme that digest organic molecules

Mitochondria

Inner membrane folds on itself to form cristae

“Power generators” of cells

Sites of cellular respiration

Cilia and Flagella

Appendages that moves the cell or moves materials over the surface of the cell

Centrioles

Involved in chromosomal movement and cytoskeleton

Contractile Vacuoles

Collect water and pump it outside the organism to maintain the organism’s internal environment

Food vacuoles

Stores food

What do plant cells have that animals cells dont

Cell Wall

Chloroplasts

Central Vacuole

Cell Wall

Surrounds membrane

Composed of cellulose

Limits absorption of water

Chloroplasts

Contain chlorophyll

Sites of photosynthesis

Central Vacuole

Stores water, sugars, wastes, pigments, defensive compounds, etc.

If the cell is broken, chemicals in the cytosol can react with chemicals in the vacuole and form toxic chemicals
