Study Notes
Cell Organelles and Their Functions
- Nucleus: Controls cell activities; materials exit through nuclear pores.
- Nucleolus: Region within nucleus where ribosomes are assembled.
- Rough Endoplasmic Reticulum (RER): Attached to the nucleus; studded with ribosomes, crucial for protein synthesis.
- Ribosomes: Dense granules; site of protein synthesis, joining amino acids to form proteins.
- Smooth Endoplasmic Reticulum (SER): Attached to the nucleus; involved in lipid production and packaging.
- Golgi Apparatus: Sorts, folds, and modifies proteins from the RER; uses vesicles for transport.
- Vesicles: Small membrane sacs for transporting materials within or out of the cell.
- Lysosomes: Specific vesicles with digestive enzymes; break down biomolecules and cell parts.
- Vacuoles: Balloon-like vesicles storing water, food, minerals, or wastes; animal cells have many small vacuoles, plant cells usually one large central vacuole.
- Mitochondria: Produces energy (ATP) through cellular respiration, converting carbohydrate energy into usable energy.
- Cytoplasm: Gel-like substance inside the cell membrane; made of water, proteins, lipids, nucleic acids, and salts.
