一己之见

A cactus (plural: cacti, cactuses, or cactus) is a member of the plant family Cactaceae, within the order Caryophyllales. The word cactus derives, through Latin, from the Ancient Greek κ�0�4κτο�0�9 (kaktos), a name originally used for a spiny plant whose identity is not certain. Cacti are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the north—except for Rhipsalis baccifera, which also grows in Africa and Sri Lanka.
Most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on earth. Cacti show many adaptations to conserve water. Most species of cacti have lost true leaves, retaining only spines, which are highly modified leaves. As well as defending against herbivores, spines help prevent water loss by reducing air flow close to the cactus and providing some shade. Cactus spines are produced from specialized structures called areoles, a kind of highly reduced branch. Areoles are an identifying feature of cacti. As well as spines, areoles give rise to flowers, which are usually tubular and multi-petaled.
In the absence of leaves, enlarged stems carry out photosynthesis. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Cactus stems also store water, and are often ribbed or fluted, which allows them to expand and contract easily. Cacti come in a wide range of shapes and sizes. The tallest free-standing cactus is Pachycereus pringlei, with a maximum recorded height of 19.2 m , and the smallest is Blossfeldia liliputiana, only about 1 cm in diameter at maturity. The smaller cacti usually have globe-shaped stems, combining the highest possible volume with the lowest possible surface area. Many cacti have a short growing season and a long dormancy and are able to react quickly to any rainfall, helped by an extensive but relatively shallow root system. A fully grown saguaro (Carnegiea gigantea) is said to be able to absorb as much as 760 liter of water during a rainstorm.
Like other succulent plants, most cacti employ a special mechanism called "Crassulacean acid metabolism" (CAM) as part of photosynthesis. Transpiration, during which carbon dioxide enters the plant and water escapes, does not take place during the day at the same time as photosynthesis, but instead occurs at night. The plant stores the carbon dioxide it takes in as malic acid, retaining it until daylight returns and only then using it in photosynthesis. Because transpiration takes place during the cooler, more humid night hours, water loss is significantly reduced.

Spent a lot of my family, but my favorite is the cactus flower. Cactus green body is kind of different. Stems and leaves its oval-shaped, flat, and each piece of the middle are two small, like a strong vigorous growth of the palm of your hand upward. His whole body covered with a brown small thorn, small thorns short, dense hand, it will mercilessly hard to root you, wah-wah bar you have pain. Cactus home in the desert regions of Africa, in particular, drought-tolerant, that is, in the arid desert, but also the survival proudly. Because the cactus stem is very thick, which can store a lot of water, the water can dry it in extreme cases of life-sustaining. Some people have done experiments, not to the cactus watering six years, it still proudly survival. He established the ability to cold, as well as indomitable vitality. Even if it's root rot, and still survive. Had a cold winter I remember, to whir north, snow goose feather floating in heaven, on the ground end of the thick ice. I did not to take care of it, a few months later, it became haggard, wither, and fade of the Baba. I watched, thinking it dead, and almost want to throw away. Who knows the following spring, the cactus or the tenacity to live over, is still as fresh, green, and become more strong, and soon, it was 23 out of yellow flowers. Cactus not only has strong vitality, but also gives medical treatment. Listen to her mother, said: If someone had mumps, put off a piece of cactus, thorn to scrape, mince, put in the neck, you can play the role of swelling. Cactus juice is said to have the efficacy of this beauty!

Cactus is the name given to any member of the flowering plant family Cactaceae. Cacti are almost exclusively New World plants. This means that they are native only in North America, South America, and the West Indies. There is however one exception, Rhipsalis baccifera; this species has a pantropical distribution, occurring in the Old World in tropical Africa, Madagascar and Sri Lanka as well as in tropical America. This plant is thought to be a relatively recent colonist in the Old World (within the last few thousand years), probably carried as seeds in the digestive tracts of migratory birds. Many other cacti have become naturalized to similar environments in other parts of the world after being introduced by people.

CACTUS [cactus]
any plant of the family Cactaceae, a large group of succulents found almost entirely in the New World. A cactus plant is conspicuous for its fleshy green stem, which performs the functions of leaves (commonly insignificant or absent), and for the spines (not always present) of various colors, shapes, and arrangements. Cactus flowers are notably delicate in appearance although usually large and showy; they are commonly yellow, white, or shades of red and purple. Many species are pollinated by bats. Cactus fruits are berries and are usually edible. A cactus plant appears on the coat of arms of Mexico, and the blossom of the giant cactus, or saguaro ( Cereus giganteus ), is the state flower of Arizona.

The plants vary from small, round globes to epiphytes, vines, and large treelike forms. The reduced leaf surface, the enlarged fleshy stem, which is well fitted to store water and to retain it, and the ramified and extensive root system (much reduced in cultivated cacti) make the plant particularly adapted to regions of high temperature and long dry periods. Cacti are not restricted to desert regions, however, for in America they range from the tropics into Canada.

Most cacti bloom in the spring for a very short period, sometimes for only a few hours. The blossoms are noticeably sensitive to light, and often different species blossom only at specific times of the day. One of the most famous of the cacti is the night-blooming cereus usually classified as Selenicereus or C. grandiflora (several other night-blooming cactus species bear the same common name). Its fragrant blossoms unfold at a visible rate after sunset and last only a single night. In many of its native habitats the flowering of this cactus is celebrated with festivals.
