Study Notes
Cellular Organelles
- Mitochondria function: Energy production
- Chloroplast function: Photosynthesis in plant cells
- Selectively permeable membrane: Allows only certain substances to pass through
- Ribosomes function: Protein synthesis
- Golgi apparatus function: Packages and distributes proteins
- Plant cell wall function: Provides support and protection
Macromolecules
- Protein building blocks: Amino acids
- Primary energy source: Carbohydrates
- Lipid function: Long-term energy storage and insulation
- Nucleic acid building blocks: Nucleotides
Cell Division
- Mitosis purpose: Produce identical daughter cells
- Human gamete chromosomes: 23
- Meiosis result: Four genetically unique cells
- Mitosis middle phase: Metaphase (chromosomes line up)
- Cytokinesis result: Cytoplasm division, creating two separate cells
Ecosystems
- Abiotic factor example: Temperature
- Organism's role in ecosystem: Niche
