Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions that allows a plant to photosynthesize during the day, but only exchange gases at night. In a plant using full CAM, the stomata in the leaves remain shut during the day to reduce evapotranspiration, but they open at night to collect carbon dioxide and allow it to diffuse into the mesophyll cells. The CO2 is stored as four-carbon malic acid in vacuoles at night, and then in the daytime, the malate is transported to chloroplasts where it is converted back to CO2, which is then used during photosynthesis. The pre-collected CO2 is concentrated around the enzyme RuBisCO, increasing photosynthetic efficiency. This mechanism of acid metabolism was first discovered in plants of the family Crassulaceae.
Crassula is a genus of succulent plants containing about 200 accepted species, including the popular jade plant. They are members of the stonecrop family (Crassulaceae) and are native to many parts of the globe, but cultivated varieties originate almost exclusively from species from the Eastern Cape of South Africa.
Didiereaceae is a family of flowering plants found in continental Africa and Madagascar. It contains 20 species classified in three subfamilies and six genera. Species of the family are succulent plants, growing in sub-arid to arid habitats. Several are known as ornamental plants in specialist succulent collections. The subfamily Didiereoideae is endemic to the southwest of Madagascar, where the species are characteristic elements of the spiny thickets.
Addo Elephant National Park is a diverse wildlife conservation park situated close to Gqeberha in South Africa and is one of the country's 20 national parks. It currently ranks third in size after Kruger National Park and the Kgalagadi Transfrontier Park.
Portulaca grandiflora is a succulent flowering plant in the purslane family Portulacaceae, native to southern Brazil, Argentina, and Uruguay and often cultivated in gardens. It has many common names, including rose moss, eleven o'clock, Mexican rose, moss rose, sun rose, table rose, rock rose, and moss-rose purslane. Despite these names and the superficial resemblance of some cultivars' flowers to roses, it is not a true rose, nor even a part of the rose family or rosid group; rather, it is much more closely related to carnations and cacti.
Crassula multicava is a perennial succulent plant from the family Crassulaceae. It is also known under various common names including the fairy crassula, pitted crassula and London pride.
Artemisia afra, the African wormwood,[4] is a common species of the genus Artemisia in Africa, with a wide distribution from South Africa, to areas reaching to the North and East, as far north as Ethiopia. Artemisia afra is the only species in this genus indigenous to the African continent.
Portulacaria is a genus of succulent plant, classified in its own subfamily Portulacarioideae in the family Didiereaceae. It is indigenous to southern Africa.
Drought tolerance is the ability by which a plant maintains its biomass production during arid or drought conditions. Some plants are naturally adapted to dry conditions, surviving with protection mechanisms such as desiccation tolerance, detoxification, or repair of xylem embolism. Other plants, specifically crops like corn, wheat, and rice, have become increasingly tolerant to drought with new varieties created via genetic engineering. From an evolutionary perspective, the type of mycorrhizal associations formed in the roots of plants can determine how fast plants can adapt to drought.
Crassula helmsii, known as swamp stonecrop or New Zealand pigmyweed, is an aquatic or semiterrestrial species of succulent plant in the family Crassulaceae. Originally found in Australia and New Zealand, it has been introduced around the world. In the United Kingdom, this plant is one of five introduced invasive aquatic plants that were banned from sale from April 2014, the first ban of its kind in the country. It is on the Global Biodiversity Information Facility's Global Register of Introduced and Invasive Species of eleven countries.
Indoor bonsai are bonsai cultivated for the indoor environment. Traditionally, bonsai are temperate climate trees grown outdoors in containers. Tropical and sub-tropical tree species can be cultivated to grow and thrive indoors, with some suited to bonsai aesthetics shaped as traditional outdoor or wild bonsai.
Crassula tetragona is a succulent plant native to Southern Africa. It is widely distributed from the Orange River boundary of Namaqualand to beyond the Kei River in the Eastern Cape. "Tetragona" comes from the phyllotaxy of the leaves. It is popularly named the "miniature pine tree" among ornamental plant enthusiasts, for its popular use as a "pine tree" in Bonsai.
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word succulent comes from the Latin word sucus, meaning "juice" or "sap".
The Albany thickets is an ecoregion of dense woodland in southern South Africa, which is concentrated around the Albany region of the Eastern Cape.
Crassula muscosa, synonyms Crassula lycopodioides and Crassula pseudolycopodioides, is a succulent plant native to South Africa and Namibia, belonging to the family of Crassulaceae and to the genus Crassula. It is a houseplant grown worldwide and commonly known as rattail crassula, watch chain, lizard's tail, zipper plant and princess pines.
Crassula ovata, commonly known as jade plant, lucky plant, money plant or money tree, is a succulent plant with small pink or white flowers that is native to the KwaZulu-Natal and Eastern Cape provinces of South Africa, and Mozambique; it is common as a houseplant worldwide. Much of its popularity stems from the low levels of care needed; the jade plant requires little water and can survive in most indoor conditions. It is sometimes referred to as the money tree; however, Pachira aquatica also has this nickname.
Crassula nudicaulis is a succulent plant native to South Africa, and Lesotho.
Ceraria namaquensis, with the common names Namaqua porkbush and Namaqua portulacaria, is a species of succulent shrub, native to the border between South Africa and Namibia.
Portulacaria pygmaea, also known as the pygmy porkbush, is a small-leaved dwarf succulent plant found on the border between Namibia and the Cape Provinces of South Africa.
Alarm photosynthesis is a variation of photosynthesis where calcium oxalate crystals function as dynamic carbon pools, supplying carbon dioxide (CO2) to photosynthetic cells when stomata are partially or totally closed. This biochemical appendance of the photosynthetic machinery is a means to alleviate the perpetual plant dilemma of using atmospheric CO2 for photosynthesis and losing water vapor, or saving water and reducing photosynthesis. The function of alarm photosynthesis seems to be rather auxiliary to the overall photosynthetic performance. It supports a low photosynthetic rate, aiming at the maintenance and photoprotection of the photosynthetic apparatus rather than a substantial carbon gain.
