What are three adaptations of plants that help reduce water loss in a desert or cold environment?

There are a variety of mechanisms- Many of the small mammals have special adaptations, such as convoluted nasal cavities and highly concentrated urine which conserves water- Many live underground, and so escape the heat of the day, and also underground is a more humid environment, so this also conserves water- Small mammals and other animals have less trouble coping with heat, because they are small, and so have a large surface area to radiate heat. The majority of activity occurs at night, so again escaping the heat...in desert climates, because the air is dry, there is significant cooling in the evening due to the fact that the air has a low heat capacity...in tropical climates heat is not as great a problem because there is plenty of water-the main way that animals cool themselves. Keep in mind, humid heat is only especially bad for humans and other sweating animals which cool themselves by evaporation. IN the absence of evaporative cooling, humidity doesn't have the same overheating effect as in humans. So, essentially it's a combination of staying underground and out of the heat of the sun during the day, and conserving water balance. IN addition, most of these animals can reduce their metabolism, thus decreasing internally generated heat.

∙ 10y ago- Concentrated urine and dry feces to reduce fluid loss.
- Hiding in cool burrows or rocky crevices by day and coming out at night for evaporation cooling.
- Becoming dormant during periods of extreme heat or drought.

∙ 12y agoDesert organisms, as cacti, have thick, round trunks to store water for long periods of drought in the future. They have especially long roots to reach far places in which water may be supplied, then stored. Animals in the desert either live in or get water from cacti so they are able to survive also.

2. Succulent plants store water in their stems, roots, or leaves.
3. Some plants have a waxy coating on stems and leaves to help reduce water loss.

2.desert animals like camel also have hooves which help them walk on the sand .

Spikes to keep animals from getting at moisture.
Long roots to go deep to get water.
Wide roots at surface to collect as much water as possible.
Large stems for lots of room.
(all of these present in a cactus)

Can humans reduce the problem of the environment?
humans cannot eliminate the problem but they can reduce .e.g by planting more and more trees ,by throwing the litter in dustbin ,by take care of already existing the plants.
Do plants reduce or oxidize carbon?
reduce
How can breeding programmes reduce the amount of pollution?
Using breeding programs develops plants with different genetic traits that can help reduce pollution. One instance of this is plants that need less fertilizer reduce the amount of nitrogen getting into water.
Using resources carefully to reduce damage to the environment is called?
Conservation.
Do trees and plants help reduce deposition or erosion?
deposition
What are structured adaptation of desert plants?
Being able to store water, and to have a waxy surface to reduce water loss, are the two main adaptations.
Do desert plants or rain forest plants have more stomata?
Yes They Do. This is because the plants in desert plants need to retain as much moisture as possible. The plants in the forest don't because its moist enough. So the plants in the forest have more stomata then plants in the desert.
Why does a cactus have spikes on it?
Desert Plants adapt to their environment by trying to reduce the amount of water lost through the leaves. At some point long ago, the leaves of desert plants got thinner and thinner until they turned spiny. Desert plants are also very good at storing water because there is so little rain that falls in the desert which is why they have such fat trunks.
Do all desert plants have spikes?
SOME desert plant have spikes, which reduce the surface area of the leaves so that the loss of water is reduced.
What are the criticisms of Julian Steward's cultural ecology theory?
the theory tends to reduce human behavior to simple adaptations to the external environment.
A thich waxy coating on the leaves of some desert plants most likely permits the plants to what?
The waxy coat helps to reduce water loss from the leaves.
Why is reducing recycling and reusing important to maintain a healthy living environment?
Then you can have a healthy and living environment to grow plants and to live there
What are some vegetations in the desert and how do they adapt to their environment?
Most vegetation in the desert are cacti and thorny bushes. Throughout many years these plants have adapted to the harsh environment of the desert. For example the spikes of a cactus allow the plant to photosynthesise but reduce the loss of moisture and harm by the animals. The cactus also has a fleshy stem to store a large quantity of water (8000 litres of water). Another adaptation of the cactus is that it´s seeds can be dormant (inactive) for several years until it rains. The plants´ roots are very long but shallow to soak as much water as possible. Some other plants can also store water in small bulbs in their roots.
What does Obama say about environment?
He believes in shutting down coal fired plants, as to reduce emissions to stop "global warming".
What is significant about plants that can grow in the desert?
A type of plants called CAM (Crassulacean Acid Metabolism) plants are suited to live in extremely dry places such as the desert. For CAM plants, they use a specialized photosynthesis that takes the carbon dioxide up during the night and closes the stomata during the day. This allows them to reduce water loss and live in that harsh environment.
How do adaptations enable organisms to reduce competition for food and other adaptations?
The classic example of adaptations is the finches living in the Galapagos Islands.
What adaptations help plants conserve water?
Adaptations that enable plants to reduce water loss from leaves are: thick waxy cuticle - reduce evaporation reduced leaf surface area (eg. needles - cacti) closing stomates at midday, when hottest or during the day - reduce traspiration fewer number of stomates store water for long periods of time and absorb it quickly, usually plants have and extensive shallow root system have long roots, and loose their leaves - reduce stranspiration and absob water from dry soil seasons, grow and die in one season Physiological adaptations being CAM plants vs C4 plants
