Cell Membrane

Cell Membrane

•outer boundary of the cell •allows only certain materials in/out of cell

– Controls osmosis – the movement of water in/out of cell–Controls diffusion – the movement of nutrients in/out of cell

•Analogy: fence

Mitochondria

Mitochondria

•breaks down food and releases energy to the cell•The more energy the cell

needs…the more mitochondria in the cell•Analogy: batteries

Nucleus

Nucleolus

Nucleus; Nucleolus; Nuclear membrane

Nucleus

Nucleolus Nuclear Membrane

Function

regulates all

cell activit

y

Contains all RNA &

DNA

Regulates the

transport of materials in and out of nucleus

What does it make?

Analogy

Brain Nerves in the brain

Skull bone

Nucleus; Nucleolus; Nuclear membrane

Cytoplasm

Cytoplasm

Gel-like substance between the cell membrane holding all the cell's internal organelles Analogy: grass

Endoplasmic reticulum

Endoplasmic reticulum

•allows molecules to be transferred

between the cell’s space and the cytoplasm •provides a pipeline between the

nucleus and the cytoplasm •Analogy: highway

RibosomesRibosome

Ribosomes

Makes proteins for the cell

Analogy: factory building

Vacuole

Animal Cell

Plant Cell

Vacuole

Animal Cell

Plant Cell

plays roles in:• digestion • release of waste products • storage

Analogy: stomach

Cilia

Cilia

Helps the cell move

Helps move things in/out of cell

Lysosome

Lysosome

Removes waste from the cell

Analogy: trash can/recycling bin

Microtubules

Microtubules

plays roles in:•cell locomotion•Mitosis (Cell Division)•cell transportAnalogy: conveyer belt

Golgi body (apparatus)

stores, packages and distributes the proteins made in ribosomesAnalogy: post office

Golgi body (apparatus)

Cell Wall (plants)

Cell Wall (plants)

prevents over-expansion when water enters the plantcellAnalogy: rubber band

Chloroplast (plants)

Chloroplast

(plants)takes energy from the sun & turns it into oxygen through photosynthesisAnalogy: kitchen
