Animal Cell:

Thin, covering, protects cells.

Protects the cell, performs active transport and passive transport, moves materials in and out of the cell.

PLANT AND ANIMAL

CYTOPLASMJelly like substance

that contains organelles

Pads and supports organelles inside the cell.

NUCLEUSPowerhouse of the

Cell – “THE BIG

KAHOONA”Dense, ball shaped

structure, contains DNA

Controls ALL of the cell’s activities

Picture:

CHROMATINIn the nucleus, made

of DNA and protein, contains genes

Provides instructions for the cells activities, (growth, reproduction)

PLANT AND ANIMAL

Picture:

ENDOPLASMIC RETICULUM – (ER)

Clear, tubular system of tunnels throughout the cell

Transports materials like proteins around the cell

PLANT AND ANIMAL

Smooth ER:

Rough ER: Difference: Contains Ribosomes (Dots on Rough ER)

RIBOSOMESSmall specks made

of RNA. Found in cytoplasm or on the rough endoplasmic reticulum

Makes proteinsPLANT AND

ANIMAL

Picture:

“MIGHTY MITOCHONDRIA”

Location in the cytoplasm, bean shaped

Supplies energy or ATP for the cell through cell respiration using glucose and oxygen

PLANT AND ANIMAL

VACUOLELarge open storage

area, smaller in animal cells

Storage tank for food, water, wastes or enzymes

CHLOROPLASTGreen structures that

contain chlorophyllCaptures sunlight

and uses it to produce food through Photosynthesis

What is Photosynthesis?

PLANT

Picture:

GOLGI BODYSmall bags with

tubes connecting them

Packages proteins for use in and out of the cell

PLANT AND ANIMAL

LYSOSOMESmall, round

structures, containing enzymes

Digests older cell parts, food or other objects
