They grow in clumps so if it is cold they are warm and if it is warm it still stays warm. :)
The fish hook shaped spines of the Fish Hook Cactus help divert heat and shade to the growing tip of the plant.
Cacti grow naturally only in the Americas, not on the African savanna.
The roots to a cactus are long thick and go very wide and deep. When it rains the roots absorb the water and store it in its leaves. The cactus doesnt need a lot of water. A couple drops a year will keep it alive. Its leaves are protected with spines.
if the new cactus can survive and reproduce (natural selection)
The characteristics that help the cactus to adapt to its harsh environment are as follows:- *It's leaves are been modified to stems which prevents transpiration and save water for the plant *It's thorns protect it from eaten by any other animal.
It can live in a desert or a rainforest, it can adapt to either.
Leaves have evolved into spines on the cactus.
it may or may not depending on speices.
In a desert, they adapt so that they are able to hold in and store more water. For example, there is a cactus.
A cactus that has flowers is giving the flowers fluids from within. A cactus is like a camel except with many more chambers. The cactus stores moisture for long periods of time.
Forest hedgehogs hibernate. However, if Desert hedgehogs are exposed to cold conditions, they die.
It doesn't adapt. Cephalocereus senilis is a species of cactus native to Guanajuato and Hidalgo in eastern Mexico and does not grow naturally in the Sahara. All cacti are natives to the Americas only and do not grow naturally elsewhere.
Firstly there are two types of deserts - hot deserts (like the Sahara) and cold deserts (like Antarctica. Generally no plants are found in cold deserts. Hot deserts on the other hand are inhospitable places in general for life, but there are plants which have manged to adapt to growing and reproducing under these conditions. There are many deserts all over the world, most contain certain plant species that are native to that area, and are not found in other deserts - for example the barrel cactus is native to central American deserts and is not found naturally in African deserts. This is a general list of plant materials that can be found in deserts, and is not specific to any in particular - some are true desert plants others are marginal desert plants: Barrel Cactus Brittle Bush Chainfruit Cholla Creosote Bush Crimson Hedgehog Cactus Desert Ironwood Joshua Tree Jumping Cholla Mojave Aster Ocotillo Palo Verde Pancake Prickly Pear Cactus Saguaro Cactus Soaptree Yucca Tuble weed Triangle-leaf Bursage Aloe species Welwitschia Opuntia species African Peyote Cactus Date Palms Olive See related links for more information:
By evolution
There are many ways in which the cacti plants have adapted to the desert including needing less water to live. These cacti plants have also developed very sharp needles to prevent animals from taking the water inside.
It's unusual for a desert cactus to grow in a cool, humidcoastal forest. The humidity tends to be too high for a desert cactus to survive. Depending upon the temperature range, it's possible that the desert cactus won't adapt to the coastal forest's cooler temperatures.A desert cactus is used to higher levels of heat and light, and lower levels of moisture and vegetative competition. But depending once again upon the temperature extremes, a jungle cactus may not be so unusual. It's used to greater vegetative competition; higher heat and moisture levels; and lower light levels. It also is used to growing up and around trees.
Deserts do not adapt but organisms that live in the desert adapt.
The desert is the environment. It does not adapt. Organisms in an ecosystem adapt to the environment.
