On the basis of their position in the plant body, meristems are grouped as apical, lateral or intercalary meristems. Echinocactus fruits may be dry and wooly or fleshy and round. As a result, stomata exposure is reduced, resulting in fewer water losses through transpiration. Cactuses of different shapes and sizes have different types of spines, from short and stubby to long and sharp. c) walk properly on the sand. Why Is Biodiversity Critical To Life On Earth?

A cactus is able to survive in the desert due to the following features: (i) It has long roots that go deep inside the soil for absorbing water. Likewise, some species have stem segments that detach easily and this combination of characteristics has earned several the common name of Jumping Cholla. While the seeds are necessary to make a consistent distinction, other more generalized guidelines help differentiate Escobaria from Coryphantha. Some Opuntias have very juicy, fleshy fruit called tunas that are harvested and turned into candies or jellies. Flowers come from woolly sections of the stem that are not developed enough to be a true cephalium. An unusual feature of Myrtillocactus is that the areoles may produce multiple flowers.
