###Â Cell Structures
- Centrioles: Small structures near the nucleus, visible under a light microscope.
- Golgi Apparatus: Discovered in 1898 by Camillo Golgi using silver stains. Processes molecules within the cell, particularly proteins.
- Cell Wall: Found in plant cells, outside the cell surface membrane. Composed of cellulose fibers.
- Cell Wall Function: Provides rigidity, shape, and prevents bursting during osmosis.
- Plasmodesmata: Connects plant cells via pores, allowing cytoplasm to move between cells.
- Cytoplasm: The living material inside a cell excluding the nucleus (cytoplasm + nucleus = protoplasm). Watery substance, varying in consistency.
- Organelles: Functionally and structurally distinct parts of a cell, often surrounded by membranes.
- Mitochondria: Most numerous organelles seen with a light microscope. Responsible for aerobic respiration.
- Cell Surface Membrane: Very thin membrane surrounding all cells. Controls exchange of materials between the cell and its environment.
- Nucleus: Large structure in eukaryotic cells containing DNA, surrounded by a nuclear envelope.
- Animal Cell Structures: Centrioles.
- Plant Cell Structures: Cell wall, large vacuoles, and chloroplasts.
- Chloroplasts: Contain chlorophyll, the green pigment that absorbs light for photosynthesis.
- Grana: Tiny "grains" or granum found inside chloroplasts, visible with a light microscope. Contain chlorophyll.
Generalised Animal Cell Structure
- Centrioles: Found by the nucleus.
- Nucleus: Contains chromatin, nucleolus, and nuclear envelope. ###Â Generalised Plant Cell Structure
- Cell Wall: Made of cellulose, encloses the plasma membrane.
- Vacuole: Large, central vacuole.
- Tonoplast: The membrane surrounding the vacuole.
- Plasmodesma: Pores between plant cells that allow for the exchange of cytoplasm.
- Cytoplasm: Surrounds the structures within the cell.
- Mitochondria: Responsible for the production energy in the form of ATP.
- Chloroplasts: Contain chlorophyll pigment and grana for photosynthesis.
- Golgi Apparatus: Small structures involved in processing and packaging proteins for export from the cell or other functions.
- Nucleus: Contains the DNA of the cell, which directs the cell's activities.
- Nucleolus: Spherical structure within the nucleus where ribosomes are made.
- Chromatin: The genetic material of the cell in the form of DNA and associated proteins.
