Question

Multiple epidermises on the dorsal and ventral sides of the leaf is found in
(a) Zea mays
(b) Nerium
(c) Ficus benghalensis
(d) Mangifera indica

Answer 1

Hint: Plants that grow in water-deficient conditions modify anatomically and morphologically and are adapted to survive in those conditions. multiple epidermises are also one such adaptation in xerophytes.

Complete answer:
In plants that grow inhabits with a deficiency of water make various adaptations to survive. one of such adaptations is the multilayered epidermis. Such plants are called xerophytes. In plants like Nerium and Ficus, Elastica epidermis has more than one layer and they have epidermis on both dorsal and ventral sides.

Additional Information: - Xerophytes are classified into three categories: ephemerals, succulents, and non-succulents. Annual plants that complete their life cycle in a short period that is mostly found in dry regions are ephemerals. Succulents store large amounts of water during the rainy season in the form of mucilage and that water is used when the conditions are day. The plants which can withstand a prolonged period of drought come under the category of non-succulents.
- Long extensive branched root hairs with well develop root caps, stunted, woody, hard stems covered with thick bark, hairs, and waxy coatings, small, scale-like leaves and sometimes modified into spines are the morphological modifications of xerophytes
- Thick cuticle, presence of silica crystals, multilayered epidermis, sunken stomata, well developed mechanical tissues, and vascular tissues are the anatomical adaptations of xerophytes.
So, the correct answer is 'Nerium'.

Note: -Tribulus is an example of ephemerals. Opuntia, aloe, and asparagus are examples of succulents. Casuarina is an example of non- succulents.
-In opuntia stem is modified, in aloe leaf is modified and in asparagus, the root is modified into succulent.
