Cornell Notes: Plant and Animal Cells

Both Plant and animal cells have a nucleus (they are eukaryotes)

Plants and animals can be either unicellular (1) or multicellular (>1)

Both plant and animal cells have some of the same organelles:

(organelles = “little organs” that do specific jobs for the cell)

Nucleus = gives directions and tells the cell what to do

Cell membrane = “selectively permeable”; controls what gets in and out

(things that get in = food, oxygen, water)

(things that get out = waste products like carbon dioxide)

Endoplasmic Reticulum (ER) = carries materials throughout the cell (conveyor belt)

Vacuole = stores food and water for later use

Mitochondria = “batteries” that provide energy for the cell

Ribosomes = make proteins

Golgi bodies = “packaging center” that add/subtract things from proteins

Plant cells have two organelles that animal cells don’t have.

1.  Chloroplast = where photosynthesis happens

2.  Cell Wall = located outside the cell membrane; supports and protects the cell

Plant cells also usually have a bigger central vacuole than animal cells

Animal cells have a cytoskeleton inside the cell that gives the cell support
