Study Notes
Cell Structure and Function
- Cells are enclosed by a plasma membrane, a selective barrier controlling nutrient entry and waste exit.
- The cell's interior is organized into specialized compartments called organelles, each enclosed by a membrane.
- The nucleus, a major organelle, houses genetic information essential for cell growth and reproduction.
- Each cell contains one nucleus, while other organelles exist in multiple copies within the cytoplasm.
- Mitochondria are responsible for energy transactions vital for cell survival.
- Lysosomes break down unwanted materials within the cell.
- The endoplasmic reticulum and Golgi apparatus play crucial roles in cellular organization by synthesizing, processing, sorting, and directing molecules to their designated locations.
- Plant cells possess chloroplasts, responsible for photosynthesis, using sunlight to convert carbon dioxide and water into carbohydrates.
- The space within the cytoplasm, called cytosol, contains the cytoskeleton, a framework of fibrous molecules that provides cell shape, enables organelle movement, and facilitates cell movement itself.
- The cytosol also houses over 10,000 different molecules involved in cellular biosynthesis, the process of creating large biological molecules from smaller ones.
