Succulent plants have thickened stems, or leaves, such as this Aloe. 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". [1]
The leaves are often vestigial, as in the case of cacti, wherein the leaves are reduced to spines, or they do not have leaves at all. These include the C4 perennial woody plant, Haloxylon ammodendron which is a native of northwest China. Non-succulent perennials successfully endure long and continuous shortage of water in the soil.
Since CAM is an adaptation to arid conditions, plants using CAM often display other xerophytic characters, such as thick, reduced leaves with a low surface-area-to-volume ratio; thick cuticle; and stomata sunken into pits. Some shed their leaves during the dry season; others (the succulents [13]) store water in vacuoles. CAM also causes taste ...
Mass flow of liquid water from the roots to the leaves is driven in part by capillary action, but primarily driven by water potential differences. If the water potential in the ambient air is lower than that in the leaf airspace of the stomatal pore, water vapor will travel down the gradient and move from the leaf airspace to the atmosphere.
When desiccated, its rooted leaves become leathery at the base, appearing dark brown or light to reddish brown. The dry ball opens a few hours after being placed in contact with water, the parched leaves gradually resuming their green colour. If the roots are not too damaged, the plant may survive in pozzolanic ash. No matter how dried or ...
Succulents are remarkable plants. Yes, you read that correctly: Using the fallen leaves and stem cuttings from the succulents in your current collection, you can grow new ones via a process known ...
Marcescent leaves may protect some species from water stress or temperature stress. For example, in tropical alpine environments a wide variety of plants in different plant families and different parts of the world have evolved a growth form known as the caulescent rosette , characterized by evergreen rosettes growing above marcescent leaves.
Wilting also serves to reduce water loss, as it makes the leaves expose less surface area. [1] The rate of loss of water from the plant is greater than the absorption of water in the plant. The process of wilting modifies the leaf angle distribution of the plant (or canopy) towards more erectophile conditions. Lower water availability may ...
