In Nerium, the stomata are present in Sunken pits. Mesophyll is well differentiated. 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. Spongy parenchyma and palisade parenchyma are present. Xerophytes are the plants growing in water scarcity. In Capparis aphylla stem, the epidermis is covered with a thick cuticle. 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. On leaves, the cuticle is 1/10 to 14 micrometers thick. They bear thick cuticles and sunken stomata on the surface of their leaves to reduce transpiration. C 3 photosynthesis 3. True & False. 8. 2.23). Openings found on the under surface of the dorsiventral leaf are Stomata. … The cuticle is located outside the epidermis and protects against water loss; trichomes discourage predation. are present. Sunken stomata to reduce water loss. Which of the following are correct for conifers ? Multilayered epidermis (e.g. ... use the cuticle in tandem with their stomata to conserve water. Explanation: Xerophytes are the plants growing in water scarcity. The leaves of the Xerophytic plants have cuticular wax. The epidermis consists of the upper and lower epidermis; it aids in the regulation of gas exchange via stomata. Aloe sp.). 6. Plants found in deserts are well adapted to cope with harsh desert conditions such as water scarcity and scorching heat. The stomata are also sunken i.e., located in depressions. All of these are xerophytic characters. All the following are adaptations in desert plants to minimize water loss except: 1. The depressions also have numerous hairs. Sunken stomata are present. Cortex: It is divisible into three parts; hypodermis, palisade and parenchyma. ), sclerenchymatous and several layered hypodermis (e.g.
III. Sunken stomata are present in the grooves. 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. Hypodermis is made of a T-shaped group of sclerenchyma in the ridges. Sunken stomata are present in the epidermis. Sunken stomata Guttation takes place generally at Night. These are covered with hairs. Plants have an extensive root system to tap underground water. 5. Stomata are …
I. Needle - like leaves to reduce surface area. 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. Thick cuticle on leaves. The epidermis is one layer thick, but may have more layers to prevent transpiration. Nerium sp.
IV. Mention, if the following statements are True or False. Pinus sp.) Leaves of Nerium are characterised by multilayered epidermis and a thick layer of cuticle. Leaves are succulent (e.g. Thick cuticle 2. Presence of myrosin cells, which are laticiferous cells, in the hypodermal region is another characteristic feature (see Fig. CAM pathway 4.
II. 7. The stomata are restricted to lower surface only. A thick cuticle is present in the outer surface of the epidermal cells. Thick cuticle is present in the epidermal layer.
