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