Study Notes
Cell Organelles in Animal Cells (1-4) and Plant Cells (5-7)
- Cell Membrane: Controls what enters and exits the cell, maintaining homeostasis
- Cytoskeleton: Provides structure and support, holds everything in place and provides a solution for chemical reactions
- Cytoplasm: A solution where chemical reactions occur
- Nucleus: Protects the DNA, which controls cellular activities. It's surrounded by an envelope with pores.
- Nucleolus: Makes rRNA (part of ribosomes) inside the nucleus
- Ribosomes: Make proteins
- Rough ER: Makes proteins, packages them, and sends them to the Golgi apparatus
- Smooth ER: Makes lipids and stores calcium ions
- Golgi Apparatus: Processes, sorts, and ships proteins from the ER
- Lysosomes: Found in animal cells, break down dead stuff and do apoptosis
- Vacuoles: Stores water, nutrients, and waste
- Centrioles: Help pull chromosomes apart during cell division (called centrosomes when paired)
- Cilia: Small hair-like structures that move fluid across the cell surface.
- Flagella: Small tail-like structures that help cells move through fluid
- Mitochondria: Where cellular respiration occurs (ATP release)
- Chloroplasts: Where photosynthesis happens in plant cells
- Cell Wall: Plant cells use this to maintain shape (made of cellulose, chitin, or peptidoglycan)
- Central Vacuole: Found only in plant cells, massive storage units in the center of the cell.
