Study Notes
Cellular Organisation
- Cells are the fundamental unit of life, making up all living organisms.
- Organisms are categorized as unicellular (single-celled, e.g., bacteria) or multicellular (made up of many cells, e.g., animals and plants).
- Microscopic size of cells requires a microscope for observation.
- Both animal and plant cells share common functions such as nutrient absorption, energy release, waste elimination, growth, and reproduction.
- Structural differences exist between animal and plant cells, influencing their specific functions.
Animal Cells
- Typically lack a rigid cell wall, which allows for varied shapes.
- Contain several organelles, including mitochondria (energy production), lysosomes (waste processing), and endoplasmic reticulum (protein synthesis).
- Highly specialized types, such as nerve cells (neurons) for signal transmission and muscle cells for movement.
Plant Cells
- Feature a rigid cell wall that provides structural support and protection.
- Contain chloroplasts for photosynthesis, turning light energy into chemical energy.
- Have a large central vacuole that maintains turgor pressure, crucial for plant rigidity and nutrient storage.
