- B2 - Topic 2 - 1.3
- Be able to describe the function of the components of an animal cell
- Animal cells are much larger than bacterial cells, with important differences from plant cells.
- Cell membrane:
- The cell contents i.e. the cytoplasm, nucleus, vacuoles, mitochondria etc.
- are all held together by the cell membrane which controls the passage of substances in and out of the cell.
- The cell contents i.e. the cytoplasm, nucleus, vacuoles, mitochondria etc.
- Mitochondria
- The energy releasing chemistry of respiration occurs in the mitochondria.
- e.g. glucose + oxygen ==> carbon dioxide + water + energy
- Mitochondria are power house of the cells and provides the chemical energy for any of the cells functions.
- The energy releasing chemistry of respiration occurs in the mitochondria.
- Cytoplasm
- Cytoplasm is a jelly like fluid in which most of the cells chemical reactions take place.
- Nucleus
- The cell nucleus contains all the DNA of the genes in the chromosomes
- This control the cells functions and the cell division of replication
- The nucleus controls the activities of the cell by sending instructions to the cytoplasm.
- The cell nucleus contains all the DNA of the genes in the chromosomes
- Glycogen granules
- Stored food for respiration.
