Answer. Unlike animals, plants cannot change their position, so whenever conditions are not favorable as per them they always show adaptations in order to meet their survival.
Generally, the plants show the structural adaptations of height
to get the maximum sunlight. Plants growing in dense forests like
Tropical rain forests show such type of adaptations to gain maximum
sunlight. As sunlight provide all the energy to carry on the
photosynthesis, thus to acquire this plants sometimes develop
climbing structures derived from roots or shoots, or sometimes
epiphytic roots that grow on the other plants. With the help of
these structures, plant reach out maximum to gain the sunlight.
More sunlight means more photosynthesis, more photosynthesis means
more food production, means the cells inside plants will divide
more quickly because if the increased activity of the meristematic
cells. More tracheids, vessels and living tissue will be added,
leading to the increase in height.
