1. 5.2 Adaptations in plants

2. STARTER
If an elephant had a small surface area compared to its volume. How will this affect it in hot climates?
Why do very small animals find it difficult to live in the artic?
Why are artic foxes white in the winter?

3. I know that plants are adapted to live in a variety of climates.
Why are these plants different?

4. Learning objectives
KQ: How do plants store water to adapt to hot conditions?
Know that
Plants must be adapted to live in a variety of climates, including deserts
Plants must be adapted to survive being eaten by animals by developing thorns, poisonous chemicals and warning colours to put animals off
There are many ways in which plants conserve water in dry environments including, extensive roots, waxy leaves, small leaves and water storage in stems
Plants lose water by evaporation through leaves.

5. Task 1: Structure of a leaf
I know that all living things have adaptations which help them to survive
Task 1: Structure of a leaf

6. Task 2: Transpiration stream
I know that plants lose water by evaporation through leaves.
Task 2: Transpiration stream

7. What are you investigating? How will you investigate this?

Task 3: Investigation
Poster?
What are you investigating?
How will you investigate this?
How will you record your results?
How will you
communicate what
you have discovered?

8. Task 5: Plant adaptations in the Desert
Plants like cacti have adaptations such as very deep or wide root systems to collect as much water as possible.
Plants that live in dry areas also need adaptations to reduce the amount of water they lose
They lose water through tiny holes (stomata) in their leaves when they make food by photosynthesis.
Draw a diagram and illustrate with words how plants are adapted to different environments

9. Is SA:V important for plants?
There are a few desert plants with broad leaves and hence a large SA. These leaves curl to catch any dew in the cold evenings, which is then funnelled to their shallow roots.
Other plants in dry environments have curled leaves which reduces the surface area and traps a layer of moist air around the leaf which reduces the amount of water they lose by evaporation.

10. Normally...
Most plants that live in dry environments have a reduced surface area. Why?
What other leaf characteristics are good for desert living?
Why do plants need water?
How do plants lose water from their leaves?
Why do plants often reduce the SA of their leaves to help them prevent water loss?

11. Conserving water

12. Three adaptations of plants Leaf (size, shape etc)

Three adaptations of plants
Leaf (size, shape etc)
Water storage methods
Keeping animals away

PLENARY

State 3 ways a plant might conserve water.
How do animals know not to eat certain plants?
