What is the characteristic feature of xerophytic plant?
Xerophytic vegetation is a characteristic feature of Kutch. Cactus, xerophytic adaptations of the rose family, are among the most drought-resistant plants on the planet due to their absence of leaves, shallow root systems, ability to store water in their stems, spines for shade, and waxy skin to seal in moisture.
What are the external features of xerophytic plants?
Adaptations of xerophytes include reduced permeability of the epidermal layer, stomata and cuticle to maintain optimal amounts of water in the tissues by reducing transpiration, adaptations of the root system to acquire water from deep underground sources or directly from humid atmospheres and succulence, or storage of …
What are xerophytic plants?
xerophyte, any plant adapted to life in a dry or physiologically dry habitat (salt marsh, saline soil, or acid bog) by means of mechanisms to prevent water loss or to store available water. Succulents (plants that store water) such as cacti and agaves have thick, fleshy stems or leaves.
Which of the following adaptation is shown by the xerophytic plants?
Solution : Xerophytic plant of deserts,has a number of adaptation to reduce transpiration for water conservation e.g. stem is covered by thick cuticle and has high succulency while leaves are modified into spines.
What are the four adaptations of xerophytes?
What are the adaptations of xerophytes? There are a huge number of xerophyte adaptations. Common adaptations include small or compound leaves, deep root systems, spines, waxy cuticle development, and a variety of stomata adaptations.
Which of the following is not the characteristics features in the anatomy of xerophytes?
So, the correct answer is ‘Spongy parenchyma’.
What are the structural adaptations found in xerophytic plants explain any five?
The following adaptations allow plants to survive in the hot desert environment: Small leaves – these ensure that less water is lost from the plant by transpiration because the leaf has a smaller surface area. Tap roots – these are long roots (7-10 metres long) that reach deep under the ground to access water supplies.
What are xerophytic plants Class 9?
Xerophytes are a group of plants that are adapted to survive in arid regions like desert and snow-covered areas. Xerophytes have stomata with microscopic openings and elongated leaves that store large amounts of water. Sometimes even their stems store water. They have deep-spreading roots that search for water.
What are major adaptations of xerophytes?
Xerophyte adaptations increase water intake, limit water loss, and store water efficiently. Water intake adaptations include deep or widespread roots, and high salt content to increase osmosis. Xerophytes have thick cuticles, lost or finely divided leaves, reduced stomata, and CAM photosynthesis.
How are Xerophytes leaves designed to suit their environment?
Xerophytic leaves are specifically adapted to aid in photosynthesis despite harsh, hot, and dry environmental conditions. A key adaptation for many is a waxy cuticle that coats the entire leaf, preventing water loss and stabilizing temperature.
What are the adaptive features of xerophytes for Class 6?
|They are structural and functional changes in an organism that help it to survive in its habitat.||They are behaviours of an organism to help it to cope with changes in their surroundings.|
|They develop over a long period of time.||They are sudden and spontaneous changes.|
Which of the following is a xerophytic character?
So, the correct answer is ‘Sunken stomata’.
What are the characteristics of xerophytic plants?
In Australian, acacia, leaf blades have been lost entirely; the photosynthetic function is taken over by the expanded petioles (phyllodes) or stems or both. The characteristics of the cells of xerophytic plants are that they are relatively small in size with small vacuoles.
How do xerophytic plants prevent excessive evaporation of water?
The xerophytic plants have to guard against excessive evaporation of water; this they do by reducing evaporating surface. Plants form a long tap root which goes deep into the sub-soil in search of moisture.
What is the difference between xerophytic mosses and plants not adapted to desiccation?
The spherical and cubical cells of plants not adapted to desiccation have their walls further apart compared to elongated cells of many xerophytes. Certain xerophytic mosses have cells which are much elongated with narrow cell cavity; their opposite walls are almost in contact.
What is an example of xerophyte?
A more well-known xerophyte is the succulent plant Agave americana. It is cultivated as an ornamental plant popular across the globe. Agave nectar is garnered from the plant and is consumed as a substitute for sugar or honey. In Mexico, the plant’s sap is usually fermented to produce an alcoholic beverage.
