The area around the Sahara Desert is slowly changing into a dry region, similar to the desert. Which trait is most likely to be
selected in the population of plants growing in this region? A.
trait encoding for short plant structure to reduce transport of water
B.
trait encoding for thick bark on trees
C.
trait encoding for increased leaf size to increase photosynthesis
D.
trait encoding for fruits with toxins to evade animals
trait encoding for short plant structure to reduce transport of water
Explanation:
The Sahara Desert is a zone which receives very low or no precipitation. This region receives maximum of sunlight not received by any other biome. The soil is typically sand which is highly porous and lacks essential growth nutrients necessary for plant growth. The plants grown around Sahara Desert are xerophytic plants. These plants undergoes several adaptations in order to prevent loss of water through transpiration. Trait encoding for short plant structure to reduce transport of water is a xerophytic adaptation.
