Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats
Answer:
Explanation:
Adaptive features: is the inherited functional features of an organism that increase its fitness.
Fitness: is the probability of that organism surviving and reproducing in the environment in which it is found.
Adaptations to arid conditions:
In both hot and cold climates plants may suffer from water shortage.
High temperatures accelerate evaporation from leaves.
At very low temperatures the soil water becomes frozen and therefore unavailable to the roots of plants.
Plants modified to cope with lack of water are called xerophytes.
Loss of leaves removes virtually all evaporating surfaces at a time when water may become unavailable.
Pine tree, Cacti and Marram grass.
Adaptations to living in water:
Plants adapted to living in water are called hydrophytes.
Water lily.
The leaves contain large air spaces to make them buoyant, so they float on or near the surface.
This enables them to gain light for photosynthesis.
The lower epidermis lacks stomata to prevent water entering the air spaces, while stomata are present on the upper epidermis for gas exchange.
