Study Notes
Cell Structure
- Cell Membrane: Outer layer, semi-permeable, controls what enters and exits the cell
- Cytoplasm: Suspends organelles, provides structure
- Ribosomes: Synthesize proteins
- Smooth Endoplasmic Reticulum (SER): Synthesizes lipids, breaks down proteins
- Rough Endoplasmic Reticulum (RER): Transports proteins made by ribosomes
- Golgi Apparatus: Sorts and packs finished molecules into vesicles
- Lysosomes: Uses enzymes to break down molecules
- Mitochondria: Makes usable energy through cellular respiration
- Vacuole: In animal cells, many small vacuoles; in plant cells, one large vacuole for storage
- Nucleus: Protects DNA, stores DNA
- Nuclear Membrane: Controls what goes in and out of the nucleus, protects DNA
- Nucleolus: Creates ribosomes
Cell Cycle & Mitosis
- Interphase: Preparation for cell division
- G1: Growth, nutrients are gathered, new proteins and organelles are produced for cell division
- S: DNA replication, proteins associated with chromosomes are produced
- G2: Final preparation, organelles and structures needed for mitosis are produced. (90% of cell cycle)
- Mitosis: Cell division
Plant & Animal Cells
- Plant Cells: Have cell walls for protection and structure; chloroplasts for photosynthesis
- Animal Cells: Do Not have cell walls; centrioles are present for cell division
