How are desert plants adapted to their climate? describe the climate and give specific examples.

The climate in deserts is extremely hot and dry. Desert plants are adapted to their environment in the following ways:

1) The leafs of the desert plants are modified into spikes to prevent water loss through leaf (by transpiration). There is already scarcity of water in the desert areas that is why plants can't afford to loose water thorough leafs. So, they modify their leafs into spikes/spines which have less surface area. Less surface are exposed towards sunlight leading to lesser water loss. This is a mechanism to conserve water in hot climate.

2) Desert plants, instead of having pores have thick waxy cuticle in their leafs. This waxy cuticle prevents water loss to the environment and conserves water for the plant.

3) Plants in deserts, instead of opening their stomata during daytime open them in night. Because there is no sunlight and therefore less heat so at that time water evaporation is less. Less water tends to evaporate during that time leading to conservation of water.

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.
