Study Notes
Vacuoles
- Functions include storage, regulation of cell volume, and degradation of macromolecules.
- In plants, the central vacuole specifically aids in storing pigments, maintaining turgor pressure, and storing water.
Cell Types
- Prokaryotic cells are found in bacteria and Archaea, characterized by the absence of a membrane-bound nucleus and organelles.
Cellular Structures
- Granum: A stack of thylakoids, crucial for photosynthesis in chloroplasts.
- Stroma: The fluid-filled space within chloroplasts, surrounding the thylakoid membranes, involved in the Calvin cycle.
- Thylakoid Lumen: The compartment within thylakoids, where light-dependent reactions take place.
Microtubules
- Composed of tubulin proteins, microtubules are long, hollow, cylindrical structures approximately 25 nm in diameter, essential for maintaining cell shape and facilitating intracellular transport.
Vacuoles
- Specialized cellular compartments filled with fluids and sometimes solids, playing roles in storage and maintaining homeostasis.
Endomembrane System
- Includes integral structures such as the Golgi apparatus, lysosomes, endoplasmic reticulum, and the nuclear envelope, interacting within the cell for various functions.
Systems Biology
- An approach focusing on studying organisms through the interactions of their components, rather than analyzing each component in isolation, providing insight into their complex behaviors and functions.
