There are many different kinds of cactus plants.
For example, one stereotypical image of a cactus is of a plant that grows at ground level. In fact, some cactus plants grow high up in trees. Such cacti are called "epiphytic" because they grow "in the air" well above ground. For example, the epiphytic rat's tail (Aporocactusspp), orchid (Epiphyllum spp) and wickerwork (Selenicereus spp) cactus plants have airy roots that prefer to grow without soil.
Another stereotypical image of a cactus is of a smaller version of the giant saguaro cactus (Carnegiea gigantea), which grows into a towering 40 foot/12 meter column with branching arms. But that distinct profile is not the only shape that a cactus plant can assume. Some examples of different cactus shapes are the following:
1. The living rock or fossil cactus (Ariocarpus spp) takes on a rosette form. Most often, it is found growing underground.
2. The torch cactus (Cleistocactus spp) grows many ground-hugging, branching arms. The prickly pear cactus (Opuntia spp) also sports branching arms that look like fleshy pads.
3. The spineless Astrophytum is an example of one of the rotund types of cactus plants. Another example is the barrel cactus (Ferocactus spp), which looks exactly the way in which it is described. The chin or spider (Gymnocalycium spp) and pincushion (Mammillaria spp) cactus plants are shaped like globes. The globe-like Turk's cap cactus (Melocactus spp) has a densely spined crown that must be seen to be believed.
4. The Barbados gooseberry or rose cactus (Pereskia spp) grows as a bush, climber or tree.
Some other surprises in the cactus plant world are the beehive (Coryphantha spp) and agave (Leuchtenbergia principis) cactus plants. Both plants lack the stereotypically spreading, shallow, fibrous roots that are the hallmark of cactus plants. Instead, agave and beehive cactus plants have roots that look like some of our tuberous vegetables.
Still another surprise is the yellow peanut cactus (Echinopsis chamaecereus f. lutea). This cactus always has a color that falls within the yellow range of the spectrum. The reason lies in the plant's lack of chlorophyll. In fact, it has to be grafted onto a green cactus in order to get energizing photosynthetic products that green plants take for granted.
There are two types of cactus, columnar cactus and climbing cactus. Climbing cactus e.g dragon fruit plant.

A cactus is a plant, a dicot.
A cactus is a plant. It does not eat.
The tip of a cactus is where growth occurs in a cactus plant. If this is badly damaged the plant may die or begin to grow elsewhere in the plant giving the plant an abnormal appearance.
Yes, cactus spines are living parts of the cactus plant. They owe their existence to growth buds on the plant's surface. From the growth buds also come a cactus plant's flowers.
No, the barrel cactus is a vascular plant.
