Study Notes
Nucleus and Nucleolus
- Contains DNA, regulating cell functions and activities.
- Nucleolus is responsible for RNA production, which is essential for ribosome formation.
Cell Wall
- A thick and rigid membrane that surrounds the plant cell.
- Provides structural support and shape to the cell.
Cell Membrane
- Composed of a thin layer of proteins and fats surrounding the cell.
- Selectively permeable, allowing certain substances to enter while blocking others.
Vacuole
- Primarily filled with water, occupying a significant portion of plant cells.
- Helps maintain cell shape and water balance.
Nuclear Membrane
- Encloses the nucleus, protecting DNA.
- Regulates the exchange of materials in and out of the nucleus.
Chloroplast
- Contains chlorophyll, the pigment crucial for photosynthesis.
- Site where photosynthesis occurs, converting sunlight into chemical energy.
Mitochondria
- Converts energy stored in glucose into ATP, the energy currency of the cell.
- Known as the "powerhouse" of the cell due to its role in energy production.
Cytoplasm
- A jelly-like substance that supports and holds organelles in place.
- Provides protection and facilitates movement of materials within the cell.
Amyloplast
- Specialized organelle responsible for starch storage in some plant cells.
- Contributes to energy reserves for the plant.
Rough ER and Smooth ER
- Rough ER is studded with ribosomes, involved in protein synthesis and material transport.
- Smooth ER lacks ribosomes, primarily responsible for lipid synthesis and detoxification processes.
Ribosomes
- Composed of RNA, critical for protein synthesis.
- Can be found free in the cytoplasm or attached to the rough ER.
Golgi Body (Apparatus)
- Modifies, processes, and packages proteins, lipids, and carbohydrates.
- Plays a key role in membrane formation and secretion of substances.
