Reproduction is the process by which living organisms multiply themselves. They do this through two major ways namely: asexually and sexually. Sexual reproduction involves two organisms (male and female) that each donate a gamete (sperm and egg). In plants, the sexual reproductive structure is the FLOWER. The male flower is called STAMEN, while the female flower is called PISTIL.
However, plants can also be propagated asexually by making use of certain plant parts including tubers, leaf etc. TUBER is a structure in plant specifically used to asexually reproduce plants like yam, potato, cassava etc.

The vascular cambium produces secondary phloem and xylem tissue.
Vascular cambium, a plant tissue located between the xylem and the phloem in the stem of a vascular plant. It is also the source of both secondary xylem growth and the secondary phloem growth. Vascular cambium is usually found on dicots and gymnosperms not on monocots which usually lack secondary growth. It does not transport water, dissolved food or minerals by plants.Vascular cambia are cylinders of unspecialized meristem cells which divide to make new cells which specialize to form secondary vascular tissues.<span> </span>
