Study Notes
Cytoskeleton Function
- Provides structural support and shape to the cell.
- Facilitates intracellular communication by organizing cell components and signaling molecules.
Cytoplasm Location
- Primarily found between the cell membrane and the nucleus.
Cytoplasm vs. Protoplasm
- Cytoplasm is generally larger in volume compared to protoplasm, which encompasses both cytoplasm and nucleus.
Composition of Cytoplasm
- Mainly composed of water, salts, and organic molecules such as proteins, lipids, and carbohydrates.
Protoplasm Location
- Protoplasm exists within the cell, including both the cytoplasm and nuclear material.
Cytoskeleton and Communication
- Acts as a communication network by transmitting mechanical signals, influencing cell function and development.
Major Component of Cytoplasm
- The cytosol, which is the fluid part of the cytoplasm, constitutes a significant part.
Circular Movement of Cytoplasm
- Described as cytoplasmic streaming, which helps distribute nutrients and organelles effectively within the cell.
Cytoplasm Delimitation
- The cell membrane separates the cytoplasm from the cell wall in plant cells.
Membrane Delimiting Cytoplasm from Vacuole
- Vacuolar membrane or tonoplast serves as the barrier between cytoplasm and vacuole.
Protoplasts Definition
- Protoplasts are living cells without a cell wall, retaining the cytoplasm and organelles.
Cytoplasm Definition
- Gel-like substance within the cell where organelles are suspended, enabling biochemical processes.
Cytosol Function
- Acts as the medium for biochemical reactions and facilitates the transport of various substances within the cell.
Major Cytoplasm Component
- Water constitutes a significant percentage of the cytoplasm, along with macromolecules.
Plasma Membrane vs. Cytoplasm
- The plasma membrane defines the cell's outer boundary, while the cytoplasm contains the inner cellular components.
Substance Between Membrane and Nucleus
- The nucleoplasm serves as the viscous fluid between the cell membrane and the nucleus.
Cell Shape Maintenance
- The cytoskeleton plays a crucial role in maintaining the cell's shape and providing structural integrity.
Fluid Portion of Cytoplasm Composition
- After organelle removal, the fluid portion consists mainly of cytosol, which contains dissolved nutrients, ions, and small molecules.
