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