One adaptation shown by hydrophytes in fresh water habitats is the

A. waxy cuticle on shoot surface

B. poor development of roots and xylem tissues

C. well-developed roots and supporting system

D. leaves reduced to spines




Much availability of water makes the development of certain features unnecessary and others necessary.

Now for the right answer to the above question:

  1. Option A is incorrect; waxy cuticle is the waxy layer usually secreted by the epidermis to prevent water loss. This entails that waxy cuticles will be needed by xerophytes and not hydrophytes, as there is enough water available.
  2. Option B is correct; poor development of roots is understandable, the main purpose of root in the first place is to source for water underground. Because there is enough water available, less development of the root is expected. The xylem tissues, which are the medium of water transportation are also expected to be less developed since there will be less need to actively transport water.
  3. C is incorrect; the roots does not need to be well developed as water could easily be absorbed through all the parts of the plant.
  4. D is not the correct answer; leaves often reduce to spines to reduce transpiration and prevent water loss, plants in the desert do this to survive dry conditions.

You may please note that:

  • Hydrophytes are plants that live in an environment with high water content, this is why they do not need developed root and xylem tissues.
  • Mesophytes are plants that live in an environment with moderate water content.   
  • Xerophytes are plants that live in a dry environment with low water content.
