Study Notes
Cytoplasm Components
- Fills the space between the nucleus and cell membrane, providing structural support.
- Cytosol is the fluid part of cytoplasm, primarily composed of water and excludes organelles.
Organelles and Their Functions
- Endoplasmic Reticulum: Network of membranes involved in protein and lipid synthesis.
- Golgi Apparatus: Processes, sorts, and distributes proteins and lipids synthesized in the ER.
- Vesicles: Membranous sacs utilized for transporting or storing a diverse range of compounds.
- Peroxisome: Single membrane-bounded organelle containing digestive enzymes that break down toxic substances.
Cytoskeleton
- A network of fibers providing mechanical support, cell shape, and facilitates movement.
Centrosome
- Small, dense region in the cytoplasm that acts as the primary microtubule organizing center, essential for cell division.
Movement Structures
- Cilia: Short, hair-like structures that aid in locomotion and movement of substances across the cell surface.
- Flagella: Longer, tail-like structures that propel eukaryotic cells, providing motility.
