Cell Parts and Functions
Information
Types of cells
1. animal
2. plant
3. bacteria
prokaryote
- cells that have no nucleus or specialized organelles
Example: bacteria and blue-green algae
eukaryote
- cells that have a nucleus and organelles
Example: plant and animal cells

eukaryote
Cell parts –
plant & animal
Cell Parts and Functions
Information
- cells that have a nucleus and organelles
Example: plant and animal cells
nucleus
(AKA brain) - controls the cells activities
nuclear
membrane
- protects and defines the nucleus
chromatin
- genetic material
nucleolus
– makes ribosomes
cytoplasm
mitochondria
– cell substance between nucleus & cell membrane – has
consistency of jelly
(AKA the powerhouse of the cell) – produces energy

Cell Parts and Functions
Information
endoplasmic
reticulum (ER)
– an interconnected network of tubules, vessicles, and sacs
that produce and transport a variety of cell substances
ribosomes
– produce protein – have the shape of grains of rice
vacuoles
(AKA mailroom) – receives proteins and distributes throughout
cell
(AKA storage tank) – stores food/water until needed
lysosomes
– breaks down larger pieces of food into smaller ones
cell membrane
(AKA gate keeper) – lets things in and out of cell
golgi bodies

cell membrane
Cell Parts and Functions
Information
cell membrane (AKA gate keeper) – lets things in and out of cell
Cell parts –
plants only
chloroplast
chloroplast – captures sun’s energy to produce food (sugar)
cell wall
cell wall – gives the cell rigidity – lets things in and out of cell
Cell parts –
bacteria only
Has four main components:
1. Cell wall
2. Cell membrane (AKA plasma membrane)
3. ribosomes
4. chromosome
