Study Notes
Cell Organelles Overview
- Cells are the basic structural and functional units of living organisms.
- Their primary functions include maintaining shape, providing mechanical resistance, and aiding in cellular movement during cytokinesis.
Cilia and Flagella
- Cilia: Hair-like projections on the cell surface that function to move the cell or the surrounding fluids.
- Flagella: Longer structures compared to cilia, also involved in cell movement.
- Eukaryotic flagella have a distinct structural composition from prokaryotic flagella.
- The axoneme, the core of cilia and flagella, consists of nine pairs of peripheral microtubules and a central set of microtubules.
- Central microtubules are interconnected by a bridge, while peripheral pairs connect to a central sheath via radial spokes.
Centrosome and Centrioles
- The centrosome consists of two orthogonal centrioles.
- Each centriole is made up of nine peripheral fibrils of tubulin protein arranged in triplets.
- Centrioles form basal bodies for cilia and flagella and create spindle fibers during cell division.
Vacuoles
- Vacuoles: Irregularly shaped, fluid-filled organelles that serve as storage bubbles within cells.
- They store food, nutrients, and waste products, playing a protective role in keeping the cell uncontaminated by harmful substances.
- Other membrane-bound organelles include the nucleus, chloroplasts, and lysosomes.
Nucleus
- The nucleus is the largest organelle within the cell, housing genetic material.
Importance of Understanding Cell Organelles
- Knowledge of cell organelles is crucial for comprehending their various functions and the overall cellular process.
- This understanding forms the foundation for further studies in biology and related subjects.
