By the end of the powerpoint students would have covered: **4.1.1.3 Cell specialisation ** Students should be able to, when provided with appropriate information, explain how the structure of different types of cell relate to their function in a tissue, an organ or organ system, or the whole organism. Cells may be specialised to carry out a particular function: sperm cells, nerve cells and muscle cells in animals root hair cells, xylem and phloem cells in plants. **4.1.1.4 Cell differentiation ** Students should be able to explain the importance of cell differentiation. As an organism develops, cells differentiate to form different types of cells. Most types of animal cell differentiate at an early stage. Many types of plant cells retain the ability to differentiate throughout life. In mature animals, cell division is mainly restricted to repair and replacement. As a cell differentiates it acquires different sub-cellular structures to enable it to carry out a certain function. It has become a specialised cell.

By the end of the powerpoint students would have covered: Active transport moves substances from a more dilute solution to a more concentrated solution (against a concentration gradient). This requires energy from respiration. Active transport allows mineral ions to be absorbed into plant root hairs from very dilute solutions in the soil. Plants require ions for healthy growth. It also allows sugar molecules to be absorbed from lower concentrations in the gut into the blood which has a higher sugar concentration. Sugar molecules are used for cell respiration. Students should be able to: describe how substances are transported into and out of cells by diffusion, osmosis and active transport explain the differences between the three processes.

Designed for the new specification AQA GCSE course but can be modified for other exam boards. 15 slides covering animal and plant cells. By the end of the powerpoint students would have covered: **4.1.1.2 Animal and plant cells ** Students should be able to explain how the main sub-cellular structures, including the nucleus, cell membranes, mitochondria, chloroplasts in plant cells and plasmids in bacterial cells are related to their functions. Most animal cells have the following parts: -a nucleus -cytoplasm -a cell membrane -mitochondria -ribosomes. In addition to the parts found in animal cells, plant cells often have: -chloroplasts -a permanent vacuole filled with cell sap. Plant and algal cells also have a cell wall made of cellulose, which strengthens the cell. Students should be able to use estimations and explain when they should be used to judge the relative size or area of sub-cellular structures.
