Nucleus
Nuclear Envelope
Nuclear Pore
Nucleolus
Chromatin/Chromasomes
The part of the cell outside the nucleus
"Jelly filling"
Organelles
"Little organs"
Specialized functions
Ribosomes
Read RNA to make proteins
Rough Endoplasmic Reticulum (Rough ER)
Helps with protein synthesis
chemically modifies proteins
Smooth Endoplasmic Reticulum (Smooth ER)
No ribosomes
Makes membrane lipids
Golgi Apparatus
Modifies, sorts, and packages proteins
The "UPS" of the cell
Lysosomes
Breaks down lipids, proteins, and useless organelles.
The cell's "clean-up crew"
Plant Cell
Storage
Much larger in plants
Mitochondria
Process energy from food
Maternal DNA!
Process energy from food
Photosynthesis
Makes energy from sunlight
Centrioles
Help during cell division (reproduction)
