what are xerophytes

these are plants are adapted to living in dry conditions

1 of 7

general features of xerophytes

thick waxy cuticle - fewer stomata - hairy leaves - smakk or needle-shaped leaves - stomata located in pits sunk into the epidermis -

2 of 7

cacti adaptation

water storage - fleshy body to retain water spines prevent animals from stealing water - water collection - wide extensive roots

3 of 7

adaptations of marram grass

live in in costal sand dunes - rolled leaf - lower suface are to volume ratio and humidity trapped- stomata sunken - hairs - thick waxy cuticle

4 of 7

what are hydrophytes

these are plants that are specifically adapted to live in water rather than soil

5 of 7

what are challenges faced by hydrophytes

have to get oxygen to submerged tissues - have to keep afloat to get sunlight - high humidity above the surface of water greatly reduces the rate of transpiration

6 of 7

adaptations of hydrophytes

large air spaces in their spongy mesophyll to give boyancy - leaf stems have many air spaces to allow oxygen to diffuse to roots - stomata on the upper surface of the leaf to allow gas exchange - using hydathodes to increase transpiration rates
