phloemu
Phloem is a specialized tissue in plants that is responsible for the transport of organic nutrients, particularly sugars, from the leaves to other parts of the plant. It is one of the two types of transport tissue in vascular plants, the other being xylem, which transports water and minerals. Phloem is composed of several types of cells, including sieve tube elements, companion cells, phloem parenchyma, and phloem fibers. Sieve tube elements are the primary cells involved in the transport of sugars, while companion cells support and protect them. Phloem parenchyma cells store and process nutrients, and phloem fibers provide structural support.
The structure of phloem varies depending on the type of plant. In dicots, phloem is typically found
The transport of sugars through phloem is an active process that requires energy. This energy is provided
Phloem plays a crucial role in the overall health and functioning of plants. It ensures the distribution
