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