3. Lesson 8 - Differentiation Learning Objectives define the term differentiation, with reference to production of xylem vessels and phloem sieve tubes from cambium describe and explain, how cells of multicellular organisms are specialised for particular functions explain the meaning of the terms tissue, organ and organ system Success Criteria Produce a resource to show how each of the cell types is differentiated Describe how the cell’s differentiation allows it to fulfil its role Produce an annotated diagram or list to show how plant tissues cooperate for maximum photosynthesis.

4. Spec. Check describe and explain, with the aid of diagrams and photographs, how cells of multicellular organisms are specialised for particular functions, with reference to erythrocytes, neutrophils, epithelial cells, sperm cells, palisade cells, root hair cells and guard cells; explain, with the aid of diagrams and photographs, how cells are organised into tissues, using squamous and ciliated epithelia, xylem and phloem as examples;

5. Peer mark your resources How well does the resource answer each of the Learning Objectives? Give a score out of 5 for each objective. Think about detail, clarity Accuracy of detail, drawings QWC, clever ways to remember ideas

6. Photosynthesis Leaves are the major organs of photosynthesis. The cells, tissues and shape are arranged to maximise photosynthesis. The products of photosynthesis need to be removed after they have been made, oxygen must be removed, Starting materials, such as light, water, carbon dioxide must be able to get to the leaf. Draw a leaf and label it to show how it maximises photosynthesis. Draw and annotate a guard cell. What contribution does it make?
