2.23). are present. This organization is to protect the stomata, which can show peripheral photosynthetic tissue and central water storage issue (diagrammatic); B, a portion (detailed) showing thick cuticle, thickenings on the radial and outer walls of the epidermal cells and sunken stomata exist in furrows. Explanation: Xerophytes are the plants growing in water scarcity. Hypodermis is made of a T-shaped group of sclerenchyma in the ridges. C 3 photosynthesis 3. The stomata are restricted to lower surface only. Leaves are succulent (e.g. Solution: Conifers have a number of xerophytic characters such as needle-like (e.g., Pinus), scale-like (e.g., Thuja) or small and leathery leaves (e.g., Araucaria), thick cuticle, sderenchymatous hypodermis and sunken stomata to reduce transpiration. Plants have an extensive root system to tap underground water. True & False. Plants found in deserts are well adapted to cope with harsh desert conditions such as water scarcity and scorching heat. Leaves of Nerium are characterised by multilayered epidermis and a thick layer of cuticle.
III. Mesophyll is well differentiated. 6. Pinus sp.) The cuticle is located outside the epidermis and protects against water loss; trichomes discourage predation.
II. Reduces Water Loss. These plants show a number of adaptations to conserve water, like presence of thick cuticle layer, reduction in size of leaves to scales or spines, multilayered epidermis and sunken stomata in leaves. Guttation takes place generally at Night. Cortex: It is divisible into three parts; hypodermis, palisade and parenchyma. Presence of myrosin cells, which are laticiferous cells, in the hypodermal region is another characteristic feature (see Fig. CAM pathway 4. All of these are xerophytic characters. Xerophytes are the plants growing in water scarcity. Openings found on the under surface of the dorsiventral leaf are Stomata. The stomata are also sunken i.e., located in depressions. 5. In Nerium, the stomata are present in Sunken pits. These plants show a number of adaptations to conserve water, like presence of thick cuticle layer, reduction in size of leaves to scales or spines, multilayered epidermis and sunken stomata in leaves. Sunken stomata are present. Sunken stomata to reduce water loss. The leaves of the Xerophytic plants have cuticular wax. Mention, if the following statements are True or False. Sunken stomata A thick cuticle is present in the outer surface of the epidermal cells. 7. The depressions also have numerous hairs. All the following are adaptations in desert plants to minimize water loss except: 1. Aloe sp.). In Capparis aphylla stem, the epidermis is covered with a thick cuticle.
I. Needle - like leaves to reduce surface area.
IV. On leaves, the cuticle is 1/10 to 14 micrometers thick. ), sclerenchymatous and several layered hypodermis (e.g. Multilayered epidermis (e.g. Sunken stomata are present in the grooves. Spongy parenchyma and palisade parenchyma are present. Sunken stomata are present in the epidermis. … Which of the following are correct for conifers ? Thick cuticle on leaves. These are covered with hairs. The epidermis is one layer thick, but may have more layers to prevent transpiration. Nerium sp. 8. Stomata are … The epidermis consists of the upper and lower epidermis; it aids in the regulation of gas exchange via stomata. They bear thick cuticles and sunken stomata on the surface of their leaves to reduce transpiration.
