Plant adaptations

Question 1

Why do adaptations help plants?

Answer 1

They allow them to survive in extreme conditions

Question 2

Where might plants need adaptation?

Answer 2

• deserts
• hot or dry conditions
• sand dunes
• windy areas

Question 3

What do plants in a rain forest have to be adapted to?

Answer 3

wet conditions and low light intensity

Question 4

Name 3 adaptations of plants in a rainforest.

Answer 4

• large leaves to take in as much light as possible
• stems and leaves that climb up trees to obtain more light with the roots in the ground
• leaves with ‘drip tips’ so water runs off them

Question 5

Why do plants have to adapt to waterlogged conditions?

Answer 5

-waterlogged soils have no air spaces so the root cells have difficulty obtaining oxygen for respiration

Question 6

Name 2 adaptations of waterlogged conditions.

Answer 6

• spongy tissue in the roots that stores oxygen

- fine surface roots that take in oxygen at the water surface

Question 7

Name and explain 5 adaptations of dry conditions.

Answer 7

-less stomata on underside of leaf
reduces amount of water lost through transpiration

-rolled up leaves
enables stomata to be on inside, reducing water loss

-spine shaped leaves
reduces surface area of the leaf

-waxy cuticle on outside of plant
stops water vapour escaping through epidermis

-widespread root system
deep and spread out to collect as much water as possible from the ground
