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.

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;

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

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?
