Vascular tissue in Plants | Xylem and Phloem

Vascular tissue is composed of xylem and the phloem. Xylem, which is the material you think of as wood, conducts water and dissolved mineral salts forming a continuous system that runs throughout the plant body.

Transpiration is the evaporation of water from plants. It occurs basically at the plant’s leaves while their stomata are open for the passage of carbon dioxide and oxygen during the chemical process of photosynthesis. The diagram of a plant below shows the movement of water from the soil into the leaves up to the leaves. This transpired water must be

Structure and Types of Stems of Plants

There are basically two types of stems – herbaceous stems and woody stems. Herbaceous plants have soft, green, juicy stems that are called herbaceous stems. They have a life span of one to two years. The cells of apical meristems are the source of all the tissues of herbaceous plants. Herbaceous stems are produced by primary growth.
