HI

Not a photo but some information on the plants we see around us

X FOR XYLEM
Xylem Definition

Xylem is a vascular tissue that transports water and dissolved minerals absorbed from the roots to the rest of the plant.

The term xylem is derived from the Greek word 'xylon' which means wood as the best-known xylem tissues are found in the woody part of the stem.
When observed under the microscope, xylem tissue has a star-like appearance.
The cells in this tissue are mostly dead cells, and the cells are lignified. The cell wall is thick and made up of lignin which aids in its function of providing support.
Xylem is present at the center of vascular bundles where the transport of water and mineral is unidirectional. The quantity of xylem is more than the phloem in these bundles.
Xylem tissue is made up of several kinds of cells. Tracheids or trachery elements are specialized, water-conducting cells that help in transport as well as provide physical support.
The next groups of cells are vessel elements that are shorter than tracheids but also help in transport. Vessel membranes have perforations through which the water and dissolved minerals are conducted.
Vessel elements are found in flowering plants where they are connected to form one continuous vessel. These elements are found not in gymnosperms.
Besides, xylem also contains parenchyma that provides support to the plant in the form of long fibers in the soft parts of the plant.
The initial development of xylem occurs from the active root cells and apical meristem, which give rise to primary xylem.
In hard and woody plants, secondary xylem develops as rings around the primary xylem as the plant expands in girth.
Ultimately, the primary xylem dies and loses its conducting function but acts as a skeleton providing physical support.
The secondary xylem continues to function as a water-conducting tissue.
In mature and woody plants, the wood or xylem is differentiated into heartwood and sapwood. The heart represents the primary xylem and provides mechanical strength, whereas the sapwood is the secondary xylem that conducts water and minerals.
The transport of water and minerals in the xylem is a passive process where no energy is required for the transport of these substances.
The functions of xylem include replacing the water lost during photosynthesis and transpiration by absorbing it from the root and providing physical support.
