Study Notes
Cell Structures
- Nucleus: Control center, contains genetic information
- Cytoplasm: Jelly-like substance, organelles float within
- Cell Membrane: Protects cell, controls movement in and out
- Mitochondria: Powerhouse of the cell
- Ribosomes: Protein production site
- Endoplasmic Reticulum: Transports materials within cells
- Golgi Bodies: Packages and distributes materials
- Lysosomes: Digest unwanted materials
Cell Types
- Prokaryotic: Bacteria, lack a nucleus, simple cells
- Eukaryotic: Plants and animals, have a nucleus, complex cells
Cell Theory
- All living things are composed of one or more cells
