• Write answers using full sentences. Most answers
  will require more than one sentence to explain
  clearly.
• If you use tables, diagrams and drawings, write a
  caption to explain what they are about.

• What are the main differences between plant and
  animal cells?
• What is the function of the following parts in a
  cell?
• The nucleus
• The cell wall
• The cell membrane
• The chloroplasts
• Why do animal cells not have chloroplasts?
• Why do the cells in plant roots not have
  chloroplasts?
• Some cells can live on their own. Give examples
  of single-celled organisms. Draw two and label
  the parts.
• Some cells have special purposes. Describe and
  explain the appearance and function of
• Leaf cells
• Root cells
• Lung lining cells
• Brain cells
• Red blood cells
• Muscle cells
• White blood cells
• Photosynthesis is a process that happens inside
  some plant cells. What two chemicals are taken
  in and what chemicals are produced by
  photosynthesis?
• Why are plant leaves thin and flat?

Starter

• VIDEO
• DVD BBC Class Clips 1. Cells. Use clip 2 (death

  cells, what they look like and introduces the
  difference between plant and animal cells.

19
Assignment (over two sessions)

• What are animal cells like?
• Use felt pens and a sheet of A3 paper.

  showing all the bits. Use a computer to print and
  add labels.

OBJECTIVES What are cells? What do cells look
like? What do cells do?

Next bit

• There are many different types of animal cell.
  Use books and/or the internet to find different
  animal cells. brain cells, white blood cells,
  red blood cells, skin cells, etc.
• Assemble cut-out different animal cells on a A3
  sheet. Add notes about the jobs these cells do
  and how they are adapted to these jobs. These
  sheets will be used for display and could be done
  on a computer.
• Bloggers You could do this on screen using
  suitable diagrams from the internet.
