in sand and in frozen ground. Pneumatophores are found in-(A) Mesophyte plants (B) Xerophyte plants (C) Mangrove plants (D) In all the above plants Answer: C. Question 6. Aerenchyma is found in – (a) Hydrophytes (b) Xerophytes (c) Halophytes (plants growing in salt) (d) In all plants asked Jun 15 in Plant Tissue - Internal Morphology and Anatomy by Kumkum01 ( 51.6k points) No need to conserve water. Adaptations of xerophytes-thick, waxy, cuticle-sunken stomatal pits-fewer stomata ... -aerenchyma. They are mainly found in aquatic and wetland plants. Plants adapted to live in dry climates, e.g. Aerenchyma. Ø The aerenchyma is well developed in submerged plants. Ø Thick walled sclerenchymatous cells totally absent in hydrophytes Many always-open stomata function. It is basically a sponge and very light tissue that forms air or spaces in stems, roots or leaves which then allows the exchange of various gases. Which one is a characteristic of xerophyte-(A) Aerenchyma (B) Large leaves (C) Sunken stomata (D) Poorly developed roots Answer: C. Question 7. Reduction of supporting or mechanical tissues. Ø Air chambers in the aerenchyma are filed with respiratory gases and moisture. 1 (a) Xylem parenchyma (b) Phloem parenchyma (c) Phloem fibre (d) Companion cell. It can define as the air cavities found between the differentiated mesophylls, which allows the convenient diffusion of the gases. The sclerenchyma is either found in groups or in continuous sheets. This tissue is well-developed in plants living in wet or aquatic environments (these plants are known as hydrophytes), although it can be also found in non aquatic plants under stress. Very thin/no waxy cuticle function. For example, in Banksia, there is a continuous thin sheet of sclerenchyma between the hypodermis and the … Xerophytes. Which of the following cells help sieve tubes to translocate food? Ø Mechanical tissues are absent or poorly developed in hydrophytes. The xerophytes commonly have a larger proportion of sclerenchyma in their leaf structure than is found normally in mesophytes. The channels of air-filled cavities (see image to right) provide a low-resistance internal pathway for the exchange of gases such as oxygen and ethylene between the plant above the water and the submerged tissues. Learn how to say Xerophytes with EmmaSaying free pronunciation tutorials.http://www.emmasaying.com (C). Aeriferous parenchyma or aerenchyma contains large intercelular empty spaces, larger than in other plant tissues. tap roots and widespread, shallow roots ... large surface area of stems and roots, air sacs, aerenchyma and pneumatophores. Fimbristylis dichotoma recorded from the saline waterlogged areas showed high proportion of aerenchyma in leaves. Cacti and marram grass. The diffused gases travel through the internal gas spaces of young leaves, then forced down to the root by the aerenchyma of the stem as a result of water pressure. Aerenchyma is a spongy tissue that forms spaces or air channels in the leaves, stems and roots of some plants, which allows exchange of gases between the shoot and the root. 1 (a) xerophytes (b) mesophytes (c) halophytes (d) hydrophytes. Xerophytes are abundantly found in (b) d) b) (d) (c) (c) well developed root system aerenchyma tissue both leaf and stem surfaces are c vere Wit t cutice none of the above fats plains (a) minerals (d) coastal areas (a) valleys (b) deserts 6. Roots are feebly developed and stem is soft with a … why do hydrophytes have a very thin or no waxy cuticle? The large air filled cavity inside it provides the internal resistance and pathway for the flow of gasses. ... give examples of root adaptations in xerophytes.
