1. What is the function of the palisade layer

  • Transparent to allow sunlight through to other layers.
  • Contains lots of air space to allow optimum gas exchange.
  • Cells towards the top of the leaf contain chloroplasts which allow maximum absorption of sunlight
  • Contain guard cells which regulate the opening and closing of the stomata.

2. Describe an experiment to investigate photosynthesis, showing the evolution of oxygen from a water plant and the requirements of light.

  • PART 3 - If the splint relights, oxygen is present. This proves that oxygen is produced through photosynthesis.
  • ADDITIONAL - If you keep the apparatus in the dark, you may be able to collect a gas, but this gas will not relight a glowing splint because it isn't oxygen.
  • PART 1 - You will need a pondweed, beaker, glass tube and a light for this experiment. Firstly, place the pondweed in a flask. Place the light facing the pondweed which will then produce bubbles of oxygen.
  • PART 2 - When the tube is full of gas, test for oxygen by putting a glowing splint quickly into the tube.

3. Why does a plant require mineral ions?

  • To be healthy and grow properly.
  • To stay alive.
  • To generate food.
  • To drink water.

4. How is a leaf adapted for photosynthesis

  • Broad and flat to provide a huge surface area for absorption of light
  • Because they are green
  • Tall
  • Their shape

5. Why does a plant require nitrates?

  • To photosynthesize.
  • To form amino acids that form proteins of cells growth.
  • To grow.
  • To breathe.
