Give in detail the anatomical adaptations shown by xerophytes ??
Answers
Plants with such morphological and physiological adaptations are xeromorphic. Xerophytes such as cacti are capable of withstanding extended periods of dry conditions as they have deep-spreading roots and capacity to store water. The leaves are waxy and thorny that prevents loss of water and moisture.
Explanation:
Plants with such morphological and physiological adaptations are xeromorphic. Xerophytes such as cacti are capable of withstanding extended periods of dry conditions as they have deep-spreading roots and capacity to store water. The leaves are waxy and thorny that prevents loss of water and moisture.
Xerophytes are the plants that grow in dry conditions with deficient supply of water.
Examples : Tribulus (Ephemeral) , Opuntia (Stem succulent) , Aloe (leaf succulent) , Asparagus (root succulent) , Casuarina (Non succulent ) ...
\large{ \bf{ \purple{Anatomical \: Adaptations \: : }}}AnatomicalAdaptations:
❇These Adaptations enable them to survive under the prevailing xeric (dry) conditions ❇
✔ Epidermis is covered with thick cuticle to reduce the rate of transpiration.
✔ Epidermal cells may have silica crystals.
✔ Epidermis may be multilayered.
✔Stomata are generally confined to lower Epidermis of the leaves (hypostomatous).
✔They are present in pits in some plants(Sunken stomata).
✔ Mechanical tissues are relatively well developed.
✔ Vascular tissues are relatively well developed.
