Q

A lower breathing rate

A

Physiological - Slower breathing = less water loss = doesn’t dehydrate. Breathing hot air in cause’s dehydration.

Q

Blood with a water content higher than the blood of other mammals

A

Physiological - The higher blood water content prevents dehydration - Go long times without water

Q

Oval-shaped red blood cells that remain functional even after significant amounts of water have been lost

A

Structural/Physiological - Allow oxygen still to be transported around the body even when there is little blood water content

Q

A large roundish body with fat concentrated in the hump and extremely thin legs

A

Structural - The hump allows for storage of fat for energy, as well as an insulator.

Q

Elevation of their leaves slightly above the hot sand

A
  • Not touching hot sand

- Conserves water - less transpiration

Q

Thick dense root fibres

A

Allow for great absorption of water. Also allows for roots to absorb the water in the air.

Q

The phloem tissues are in the middle of the roots and are surrounded by xylem

A

By having the phloem surrounded by the xylem it allows the plants to use evaporation through transpiration to cool the plant down.

17
Q

Deep root system

A

Reach water

18
Q

Densely packed leaves

A

Less surface area exposed to sun = Less Transpiration = Less water loss
