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.

Description
