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.
The cactus is one of the few plants found in the desert, and in order to survive it needs a massive amount of water. Since it does not rain all year round in a desert, cacti store water when it does rain. So the needles on the cactus protect their water-rich flesh from other things in the desert.
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.
Cactus plants belong to the group of succulent plants, which are characterized by their ability to store water in their stems, leaves, or roots. Succulent plants have adapted to arid environments, making them well-suited to survive in conditions with limited water availability.
The general name is a succulent or a cactus.
Not really
a cactus, silly (:
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.
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.
Water, dissolved nutrients, and byproductsof photosynthesis are stored in the cactus stem. The water and the dissolved nutrients are sent up into the stem from the cactus plant's roots. They're held in the stem until they can be used in the photosynthetic interaction with sunlight. From that interaction are made the energizing carbohydrates, starches and sugars that the cactus needs for such activities as flowering, fruiting, growing, reproducing, and responding to stresses and stressors.
Thirteen cactus plants can be watered once with a 4.2 liter capacity watering can. There are 4,200 milliliters in 4.2 liters. Thirteen plants use up 4,030 milliliters of water from the can. That leaves 170 milliliters, which won't meet the watering needs of cactus plant number 14. So it's at cactus plant number 14 that the gardener needs to refill the watering can.
it needs sunlight and it also needs water at least every other day.
