What are the adaptations of Mesophytes?
Mesophytes do not have any specific morphological adaptations. They usually have broad, flat and green leaves; an extensive fibrous root system to absorb water; and the ability to develop perennating organs such as corms, rhizomes and bulbs to store food and water for use during drought.
What adaptation is present in a Xerophyte?
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 is a fish adapted to live in water class 6?
The streamlined body shape helps the fish to move through the water easily (because such a shape offers least resistance to motion). (2) The fish has special organs called “gills” which-help it to absorb oxygen-dissolved in water for breathing. A fish can live in water only because it is adapted to breathe in water.
What are the adaptations of aquatic habitat?
Some of the adaptations of aquatic animals are: Their body is streamlined and hence, they can swim easily. They have gills as the respiratory organs. They have fins as the locomotory organs, Various types of fins are present in fishes such as dorsal fins, pectoral fins, caudal fins etc.
How are mesophytes adapted for transpiration?
Adaptations of mesophytes The stem is generally straight and branched. The leaves are generally broad and thin. The presence of waxy cuticle in leaves traps the moisture and lessens water loss. Leaves have stomata which close in extreme heat and wind to prevent transpiration.
How are leaves of mesophytes adapted to their function?
Biology Questions and Answers Leaves have vein, xylem and phloem to transport products of photosynthesis to other part of the plant. Air spaces on spongy mesopyll, easily circulates gases/ CO2 diffuse into palisade cells. Mosaic arrangements of leaves; enable leaves to trap sunlight.
How are plants adapted for water?
The leaves in hot or dry environments may be adapted to reduce transpiration ….Leaf adaptations.
|Waxy leaf cuticle||Impermeable to water, which stops evaporation|
|Rolled leaves, leaf hairs, and stomata sunk in pits||Traps moist air, which increases the humidity and reduces the diffusion of water vapour|
What are 6 environmental factors that contribute to transpiration?
Environmental factors that affect the rate of transpiration
- Light. Plants transpire more rapidly in the light than in the dark.
- Temperature. Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises.
- Soil water.
What special adaptations can be seen in dolphins?
These adaptations enable a dolphin to conserve oxygen. Dolphins, like other marine mammals, have a slower heart rate while diving. During a dive, blood is shunted away from tissues tolerant of low oxygen levels toward the heart and brain, which require a constant supply of oxygen.
How are frogs adapted to land and water?
They have gills that help them to breathe in the water. Their skin, when kept moist can take in oxygen dissolved in water. They have lungs that help them to breathe when they are on land.
What is adaptation of aquatic plants?
Aquatic plants require special adaptations for living submerged in water, or at the water’s surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common.
Which one of the following is an aquatic adaptation?
General Science A ir sacs or air bladder –to stay in deep water for long time. Answer: The adaptations by virtue of which an organism survives in aquatic environment are known as aquatic adaptations. For examples, fishes have presence of gills, lateral line sense organ which are included under aquatic adaptations.
