Cell Structure and Organisation

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.
