Cacti grow naturally only in the Americas, not on the African savanna.
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.
Just the same as any other flowering plants. Plants adapt to their environment by evolution some cactus are plants adapted to dry conditions.
They grow in clumps so if it is cold they are warm and if it is warm it still stays warm. :)
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.
some are the Joshua Tree, cactus some kinds of cactus is, Nopal cactus, Prickly pear cactus, and Black Lace Cactus :)
Leaves have evolved into spines on the cactus.
By evolution
no,there would be little change because the cactus wont be able to adapt to the environment.
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
well, all the animals have many ways
Because all cactus have large sacks in them like camels that hold water. >:{D
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.
it may or may not depending on speices.
Plants are not intelligent, and are not capable of learning.
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.
Animals in African savannah follow Survival of the fittest........... Their body organs and features are modified according to the climate and terrain of savannah......... for example, camouflage...... Claws......... Long necks etc.
