Study Notes
Cell Structure and Organisation
- A cell is the basic unit of life, and understanding its structure is crucial for appreciating the functions of cell components and cell specialisation.
Comparing Cell Structures
- Generalized plant and animal cells have different structures, which can be compared and contrasted.
- Microbes, such as bacteria, Protista (e.g., amoeba), have distinct cell structures.
Cell Components and Their Functions
- Cell wall: provides support and protection to the cell.
- Cell membrane: regulates the movement of materials in and out of the cell.
- Mitochondrion: responsible for generating energy for the cell through cellular respiration.
- Chloroplast: responsible for photosynthesis in plant cells.
- Nucleus: contains genetic material (DNA) and controls cell growth and reproduction.
- Cytoplasm: a jelly-like substance where metabolic processes take place.
- Vacuoles: store and transport materials, and help maintain cell turgor pressure.
Nutrition and Energy
- Nutrition is the process by which living organisms obtain energy and material requirements.
- Different organisms have different nutritional modes, such as photosynthesis, respiration, and ingestion.
