This is a lesson on plant cells

1. Plant Cells What does plant tissue look like under a microsope ?

2. Learning Objectives LO 1 . I can list the main parts of plant cells 2 . I can describe the structural adaptation of plant cells 3 . I can explain the function of parts of plant cells 4 . I can analyse the differences between different types of cell

3. Looking at Plant Cells Health and Safety Safety glasses on during slide production . Slides and coverslips are made of glass – take care when handling. Always place a coverslip over the object before viewing the slide under a microscope. Iodine solution can stain.

4. Apparatus • coverslip • iodine solution stain • pipette • slide • microscope • onion skin Be careful with iodine solution – it stains skin and clothes! Place all used slides, etc. into the place your teacher shows you. Method A Take a piece of onion skin and place it on the slide. B Put a drop of iodine solution stain on the slide. C Place a coverslip on the drop of stain , lowering it gently. D Observe your cells under a microscope.

5. Drawing what you see PENCILS! Draw in as detail as you can what you see under the highest magnification

6. Levelled Task Band 2: Draw and l abel the parts of a plant cell. Try to add some of these labels to your diagram of the onion skin cells. Band 3: Explain what each of these parts do Band 4 : Explain why plant cells contain parts not found in an animal cell . Produce a comparison table. Help: p14. Extension Q1-5.
