Study Notes
Cell Organelles Overview
- Cell organelles, known as little organs, are membranous compartments within cells of living organisms, crucial for various cellular functions.
- Key functions of organelles include maintaining cell shape, storing nutrients, manufacturing proteins, harvesting energy, repairing cell parts, and digesting substances.
Functions of Cell Organelles
- Maintain structural integrity of cells.
- Serve as storage sites for vital nutrients.
- Synthesize proteins essential for cellular functions.
- Convert energy for cellular processes.
- Facilitate repair mechanisms for damaged cellular components.
- Break down and digest various substances.
Major Cell Organelles
-
Cell Membrane
- Surrounds the cell and selectively regulates the entry and exit of substances.
-
Cytoplasm
- Gel-like substance composed of dissolved proteins and fluids that fills the cell, providing a medium for cellular processes.
-
Nucleus
- Present only in eukaryotic cells; it houses the cell's hereditary DNA and governs cellular activities such as growth, metabolism, and reproduction.
- Nucleolus: A sub-organelle within the nucleus composed of proteins and RNA, responsible for synthesizing ribosomes.
