Question

Xerophytes have very small leaves or spines to
A.Reduce weight
B.Reduce loss of water
C.Reduce volume
D.Be beautiful

Answer 1

Xerophytes are plants that are evolved to survive in such a behaviourally dry habitat through means of frameworks to stop the loss of water and to store water resources. It's a type of succulent plant. They include distinctive properties to withstand these tough conditions

Complete step by step answer: The forms of adaptations of xerophytes are comprehensive. Plant species with adaptations that allow it to survive in hot temperatures are called xerophytic. Tiny leaves of xerophytic crops mean that less water is wasted by transpiration from plants since the leaf has a lower surface area. Some species have spines rather than leaves, e.g. cactus. Spines drain less water than leaves, and they're very effective in a hot climate. Spines also restrict animals from consuming crops. The anatomy and basic chemical processes of xerophytes are modified in a range of ways to save water that is also usual in the preservation of large volumes of water throughout dry seasons. Xerophytes like cactus are capable of resisting long stretches of dry conditions since they have strong roots and water storage potential. The leaves are waxy and perilous, blocking the loss of water and humidity. Even the fleshy stems are capable of storing water.
So, the correct answer is (B).

Additional information:
If the water concentration (water vapour potential) within the leaf is greater than the outside, the vapour will disperse out of leaf along this curve. This loss of vapour from the plants is called transpiration, and also the water vapour extends through stomata. For crops, transpiration is usual and highly probable; through all this process, a huge quantity of water is wasted. The leaf litter upon the ground near the plant can provide an evaporation shield to stop the water loss. The root mass of the crop itself could also carry organic compounds which retain water, like in the situation of arrow weed.

Note: It is therefore imperative that plants existing in dry environments are oriented in such a way as to minimize the size of the stomata, lower the incidence of transpiration and, ultimately, minimize the loss of water to the atmosphere.
