Structural Modifications Of Leaves To Reduce Water Loss

Question 1

Transpiration

Answer 1

Process in that water and dissolves nutrients in the soil are brought to leaves where they mainly can be used for photosynthesis.

Question 2

Plants therefore have structured modifications to prevent excessive water loss through transpiration

Answer 2

1. Stomata
2. Thickened Cuticle
3. Hair on leaves
4. Shape , size and arrangement of leaves

Question 3

Sunken stomata

Answer 3

In some plants stomata may be sunken or small e.g pinus

Question 4

Thickened cuticle

Answer 4

On surface of leave reduces rate of transpiration. E.g aloe

Question 5

Hair on leaves

Answer 5

Sheen or shine of hairs may reflect sunlight reduce transpiration. Also trap water vapor so no water loss

Question 6

Shape size and arrangement of leaves 🍃

Answer 6

Determine total SA exposed to environment, influencing rate of transpiration.
