Study Notes
Topic 2: Organisation of the Organism
- Cells: Basic units of life, specialized for specific functions
- Ciliated Cells: Move mucus in the trachea using tiny hairs (cilia)
- Root Hair Cells: Absorb water and ions from the soil, increased surface area for absorption
- Xylem Vessels: Transport water and support plants, no cytoplasm or end walls for efficient water flow
- Palisade Mesophyll: Photosynthesis, tightly packed cells with numerous chloroplasts
- Nerve Cells: Conduct nerve impulses, long axons with branches for rapid signal transmission
- Red Blood Cells: Transport oxygen, no nucleus for more space for oxygen-carrying hemoglobin, biconcave shape
- Sperm Cells: Reproduction, tail for movement, mitochondria for energy, multiple sperm prevention
- Egg Cells: Reproduction, large size, energy stores for development, multiple sperm prevention
Tissues
- Tissues: Groups of similar cells working together, performing a shared function (e.g., muscle tissue, palisade mesophyll)
Organs
- Organs: Structures made of multiple tissues working together to perform specific tasks (e.g., heart, kidney, leaves)
Organ Systems
- Organ Systems: Groups of organs working together for related functions (e.g., digestive system, circulatory system)
Cell Specialization
- Specialized cells exhibit specific adaptations for optimal function in their roles. (e.g., shape, size, and internal structure)
