Study Notes
Organelles of Animal Cells
- Nucleus: Acts as the cell's control center, housing the cell's DNA.
- Nucleolus: Located within the nucleus, responsible for the production of ribosomes essential for protein synthesis.
- Lysosome: Contains enzymes that break down waste and cellular debris, aiding in recycling cellular materials.
- DNA/Chromosomes: Carrier of genetic information; reside in the nucleus and dictate cellular functions and traits.
- Centrioles: Cylindrical structures that play a crucial role in cell division by organizing spindle fibers.
- Smooth Endoplasmic Reticulum (SER): Synthesizes lipids and steroids, detoxifies harmful substances, and stores calcium ions.
- Rough Endoplasmic Reticulum (RER): Has ribosomes on its surface; plays a key role in synthesizing and transporting proteins throughout the cell.
- Ribosomes: Small structures that are vital for protein synthesis, translating mRNA into polypeptides.
- Cytoskeleton: A network of fibers providing structural support, enabling cell shape maintenance, and facilitating organelle movement.
- Mitochondria: Known as the powerhouse of the cell, they generate ATP through cellular respiration, supplying energy for cellular activities.
- Cell Membrane: A phospholipid bilayer that protects the cell, regulating the entrance and exit of substances.
- Cytoplasm: The semi-fluid matrix that fills the cell, hosting organelles and supporting cellular reactions.
- Golgi Body: Functions in modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.
- Vesicles: Membrane-bound sacs that transport and store various substances within the cell, facilitating intracellular communication.
