Is the cactus an unusual plant?

Answer 1

Yes, the cactus is an unusual plant. It tends to be grouped into two broad categories that are based on the biome in which it's found. One group is that of the desert cactus. This group is unusual for its successful survival in the harsh, extreme environment of strong sunlight and little moisture. The other group is that of the jungle cactus. This group is unusual for its successful survival in the enervating environment of much moisture and little direct sunlight.

Answer 2

Cactus plants are unusual in their survival and success in extreme, harsh environments. They tend to fall into two broad types. One type is the plant that's native to the desert environment of high heat and light; and of low moisture and vegetative competition. The other type is the plant that's native to the jungle environment of high competition, heat and moisture, and of low light.
