Cacti and succulents can survive in the desert most likely because they both

a) need direct sun.

b) can store water.

c) have long tap roots.

d) have chlorophyll for photosynthesis.

The right answer is B) can store water.

Cactus, Cactaceae or Cactaceae (Cactaceae) are a family of flowering plants. They are almost all succulents or succulents, that is to say xerophytic plants that store in their tissues reserves of "juice" to cope with long periods of drought.

Do not confuse Cactus and succulent plant: not all succulents are Cactus. These are plant families that have adopted the same methods of combating periods of drought, such as Asclepiadaceae or Crassulaceae.
