A cactus is deeply rooted and, even in a hot desert, there may be dampness below. Also, whenever it does rain, the cactus will store water in special cells that cause the cactus to swell. Another adaptation is that a cactus's covering is waxy to prevent water loss. While it may be hot during the day, temperatures can plummet at night.

Leaves provide extra surface area for water to evaporate out of the plant. In the arid desert, plants need all the water they can get.
Photosynthesis takes place in the stem of the cactus. Needles are the cactus' equivalent of leaves. But they don't have enough surface area to support photosynthesis or to store photosynthetic byproducts. So the cactus' stem is bigger, taller, and wider than in many other plants. The cactus needs all that extra space to move around and store water, dissolved nutrients, and byproducts of the photosynthetic interaction with sunlight.
The general name is a succulent or a cactus.

a cactus, silly (:
Not really
all green plants AND all plants in general :) even a cactus plant needs water, it just needs less then conventional plants do.

That depends on what kind of plant it is. Some plants, such as cactus, do not need much water. Other kinds of plants need more. So you would have to ask about a specific plant in order to get a specific answer.It really depends on the plant. Some plants need more water than others, such as a cactus and a bean ,the bean needs more water than the cactus because the cactus stores water and beans don't.
Every plant needs a different amount of water. A good rule of thumb is to stick your finger in the soil. If you finger comes out with no mud on it then it needs watering. Another is every 3 days water your plant 3 inches.
Depends on the plant. Some require little water, some a lot. Plants have developed adaptations to different environments. A cactus growing in a dry desert takes very little water, and a succulent growing in a rain forest needs a lot.
As a cactus is a form of a plant, it will require sunlight for photosynthesis and water to stop it from drying out and to help the cactus plant grow.
A cactus?
a cactus holds water the most
The water from the cactus could be cleaner.
A cactus plant may grow faster by attention to its differing needs during the growing and dormant seasons. For example, a cactus plant responds well to regular fertilizing and watering while it's growing. The regular application of fertilizer and water tends to work best if carried out every 10-14 days. At the same time, a cactus plant tends to prefer to go without water during dormancy.An important precaution in any season is the avoidance of cold and damp. Cactus plants don't like waterlogging, which rots and kills the tissue. Neither do they like chilly temperatures.
