Cactus plants are a member of the plants family Cactaceae, a family comprising about 127 genera with some 1750 known species. The word “cactus” derives, through Latin, from the Ancient Greek κάκτος “(Kaktus)”, a name originally used for a spiny plant whose identity is not certain. Cacti occur in a wide range of shapes and sizes. Its species inhabit diverse regions ranging from the Nearctic (north of the tropic of Cancer) to the Neotropics ( south of the tropic of Capricorn), occurring in altitudes from sea level to 5800 meters.
Cactus flowers are large, and like the spines and branches arise from areoles. Which allows them to expand and contract easily for quick water absorption after rain, followed by long drought periods. Like other succulent plants, mostly cacti employ a special mechanism called “crassulacean acid metabolism” (CAM) as part C4 carbon fixation, which allows them to open stomata at night to absorb CO and fix it into organic acids, then store the fixed carbon in the form of malic acid, metabolizing it again during the day to enable photosynthesis. This adaptation enables plants growing under harsh conditions to keep cool by day and absorb CO needed for photosynthesis at night when temperatures and water availability are lower.
Cacti show many other adaptations to arid environments: thick cuticles, reduced leaf area, and spines protecting against desiccation, and ” storing leaves “, structures specialized for the development of new roots. Cactus stems store the plant’s water, and large Cacti store water as large volumes of plasmolyzed -water held in the vacuolar compartment of parenchymatous cells. Cacti can be either deciduous, suffrutescent (shrubs), or treelike, and may have a tree-like appearance.
The stems of many Cactaceae are armed with sharp spines produced from specialized structures called areoles. A kind of highly reduced branch. Their spines come in a variety of colors, which may be related to the plant’s type and where it grows. Areoles on cacti produce clusters of spines that grow out as bristles or tufts, depending on the species.
Cacti with needle-like spines are called “normal“, Cacti with yellow or white spines usually lack chlorophyll and usually contain a fluid-filled cyst. Cacti with sharp straight spines normally keep their leaves as they grow older. Its stems (or trunks) can be widely ribbed or fluted, giving them a zigzag profile. Cacti in harsh climates may be decumbent, Cacti can grow into unusual shapes, including bottle-shaped columns. Their stems have adapted to extreme weather conditions by becoming shorter and more rounded with fewer leaves to catch water under dry conditions or elongated with deep taproots to access subsoil water during drought Cacti can photosynthesize.
Flowers and Spines
Cactus flowers are the most varied of all cacti. These plants provide an interesting subject for their flower morphology. They themselves have botanical characteristics that make them easy to distinguish from other plants. Cacti produce a type of modified stem called a cladode, Cacti can survive in almost any climate.
Cacti require little maintenance. Cactus roots are one. Cacti form new shoots from buds on their stems. They have flowers. Cacti show economic uses. Their species grow with age. Cactus is a plant from the Cactaceae family Cacti roots Cactus branches, Cactus flowers have been categorized into several different types based on their morphology Cactus leaves can take many forms and structures.
Cacti can live up to Cactus stems. Cactus has been growing in the Cactaceae family. Cacti produce beautiful flowers with great variations in color and form, Cactus trees as garden plants or indoor pot plants. Cacti plants come in a variety of shapes and sizes that make them an attractive and popular addition to homes. Cactus flowers, Cactus leaves, Cactus stems, and Cacti have evolved to survive in almost any climate. Cactaceae is the only family in the order. Cacti can be classified as Cactaceae, Cactus plants, Cacti stems. Cactus flowers are the most varied of all cacti, and they show economic uses. Cactus species grow with age. It is the best thing to have, do not let it go. You should try growing it for yourself.
