Answer. To live on land, plants show
terrestrial adaptations. These are:
- They show an additional protective layer of cuticle above to
their epidermis to reduce the rate of transpiration and conserve
water.
- They possess fine pores on their aerial surface known as
stomata to regulate their internal temperature and moreover to take
CO2 from the atmosphere to carry on photosynthesis.
- Well developed vascular tissue is present in them. Means the
xylem is well developed to form trachery elements, xylem fibers and
xylem parenchyma, whereas, phloem is also well developed to show
the sieve tubes, companion cells, phloem fibers and phloem
parenchyma. Xylem is meant for water and minerals translocation and
phloem for food translocation.
- Root system is well developed to have good absorption of water
and minerals.
