Study Notes
Cellular Anatomy - Organelles
- Nucleus: Found within the nuclear membrane, it controls cell reproduction and contains DNA (hereditary material).
- Nuclear Envelope: Membrane surrounding the nucleus, containing pores.
- Nucleolus: Located inside the nucleus, manufactures ribosomes.
- Ribosomes: Produce proteins located in the cytoplasm or rough endoplasmic reticulum.
- Cytoplasm: Area between the nucleus and cell membrane; includes everything within the cell except the nucleus.
- Endoplasmic Reticulum: Connects the nuclear membrane to the cell membrane; involved in transport of cell products.
- Rough ER: Processes proteins.
- Smooth ER: Processes lipids and carbohydrates.
- Mitochondria: Power source of the cell.
- Chloroplasts: Found in plant cells; site of photosynthesis.
- Golgi Apparatus: Packages and secretes cellular products.
- Lysosomes: Enzyme-coated organelles for cellular digestion.
- Chromatin: Strands of genetic material that form chromosomes prior to cell reproduction.
- Vacuole: Primarily for storage, especially water in plants; often a large, central vacuole in plant cells.
- Cell Membrane: Regulates what enters or exits the cell.
- Cell Wall: Provides structure and support for plant cells (Animals cells do not have cell walls).
Additional Cellular Components
- Centrioles: T-shaped or barrel-shaped structures involved in cell division in animal cells.
- Centrosomes: Similar structures in plant cells that perform similar functions to centrioles.
- Fungi and Bacteria: These organisms have cell walls, but their structures are designed differently than plant cell walls.
