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 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?
-----------
Ribosomes
-------------------
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
