Cell parts (Organelles)
Organelles “little organs”
Nuclear Membrane
Nucleolus
Chromatin
NucleusNickname : Control center
Nucleus cont.
• Nuclear Membrane
• Function - control what goes into or out of the nucleus
• Nucleolus
• Function - make Ribosome's
• Chromatin
• Function - controls the cell sends out instructions
Ribosomes
Electron micrograph
Ribosomes - assemble proteins
Nickname : Workers
Electron micrograph
Endoplasmic Reticulum also called ER
Rough ER - Help make proteins
Smooth ER - Help make lipids and detoxify toxins
Nickname : Assembly line
Electron micrograph
They have their own
DNA
MitochondriaNickname : Powerhouse
Mitochondria - makes energy in the form of ATP (cellular respiration)
Golgi Complex
Electron micrograph
Nickname : Post office
Golgi - sort, modify and package proteins and lipids
Lysosomes
• Function - digest old membranes, organelles, food particles or virus/bacteria
Nickname : Garbage men
Vesicle
• Function - cellular package to move things like proteins
Nickname : UPS truck
Cytoskeleton
• Cytoskeleton - the filaments that help maintain the shape of cell.
• Microtubules
• Cilia
• Flagellum
• Cilia and flagellum have the same pattern of microtubules
Chloroplast
Found in Plant cells onlyChloro = Green
They have their own
DNA
•Chloroplast - convert the suns energy into chemical energy
Nickname : Solar panel
Central Vacuole
• Central Vacuole - store sugars, salts and proteins
Cell wall
• Function - provide protection and support (found in plants)
Wood is made up of cell walls
Contractile vacuole
Contractile vacuole - pump out excess water
Animal cell
Plant cell
