Cell Organelles Study Notes

Nucleus: Acts as the cell's control center, regulating its activities and housing genetic instructions essential for its functions and traits.
Nucleolus: Located within the nucleus, this organelle is responsible for the production and partial assembly of ribosomes.
Cytoplasm: A gelatinous substance that fills the interior of the cell, providing a medium where organelles are suspended and engaged in cellular processes.
Centrosome: Situated near the nucleus, it is crucial for the organization of microtubules, which are vital for cell shape and division.
Golgi Apparatus: A key player in the cell's protein processing system, it modifies, sorts, and packages proteins for transport to various destinations within or outside the cell.
Lysosome: Containing digestive enzymes, lysosomes break down waste materials and cellular debris, primarily found in animal cells.
Cell Membrane: This semi-permeable barrier encases the cell, controlling the ingress and egress of substances, crucial for maintaining cellular homeostasis.
Mitochondria: Known as the cell's powerhouse, mitochondria convert nutrients into energy through cellular respiration, essential for various cellular activities.
Vacuole: A storage organelle that holds water, nutrients, and waste products; notably, plant cells have large vacuoles that help maintain cell turgidity.
Smooth Endoplasmic Reticulum (ER): Serves as a network of passageways for transporting proteins, devoid of ribosomes, and involved in lipid synthesis.
Rough Endoplasmic Reticulum (ER): Studded with ribosomes, this structure is involved in the synthesis and transport of proteins.
Ribosomes: These organelles are the sites of protein synthesis, translating messenger RNA into polypeptide chains.
Cytoskeleton: Composed of a network of fibers, it maintains cell shape, provides structural support, and facilitates cellular movement.
Chloroplasts: Exclusive to plant cells, chloroplasts harness sunlight to produce food through photosynthesis, containing chlorophyll, the pigment responsible for trapping light energy.
Cell Wall: A rigid outer layer found only in plant cells, it surrounds the cell membrane, providing structural support and defining the cell's shape.
