A plant species lives in an area with limited sunlight. Which physiological adaptation would be most useful to the plant?
A
deep roots
B
thin cuticle
C
large leaves
D
colorful flowers
Explanation: 

Detailed explanation-1: -Plants living in deserts have adaptations such as hair on leaves and a thick cuticle.

Detailed explanation-2: -Some plants can survive in very low-light conditions. If you think about dark, rainforest canopies, there are plants that grow in that environment. They have evolutionary adaptations to handle these low-light environments, which include making broad, thin leaves to capture as much sunlight as they can.

Detailed explanation-3: -Physiological adaptations in plants Physiological adaptations of plants are processes which allow them to compete. An example of this is the formation of poisons for defence. The nettle plant stings us when we brush the tiny needles on its leaves, which contain poison.

Detailed explanation-4: -How are plants adapted to photosynthesis? Leaf increases its surface area to absorb more sunlight. The presence of a cuticle prevents the loss of water. The thin structure of leaves allows carbon dioxide to reach easily.

Detailed explanation-5: -All plants require light for photosynthesis, the process within a plant that converts light, oxygen and water into carbohydrates (energy). Plants require this energy in order to grow, bloom and produce seed. Without adequate light, carbohydrates cannot be manufactured, the energy reserves are depleted and plants die.
