Transport System in plants
Transport System in plants The transport system in plants refers to the network of tissues and structures responsible for the movement of water, minerals, sugars, and other substances throughout the plant. It allows for the distribution of essential nutrients and the removal of waste products. There are two main types of transport systems in plants: 1. Xylem: The xylem transports water and minerals from the roots to the rest of the plant. It consists of long, hollow, and dead cells called tracheids and vessel elements. These cells are connected end-to-end, forming tubes that allow for the upward movement of water from the roots to the leaves. Some examples of plants with xylem are trees, shrubs, and other vascular plants. 2. Phloem: The phloem transports sugars, nutrients, and other organic compounds, such as hormones, from the leaves to the other parts of the plant. It consists of living cells called sieve tube elements and companion cells. Sieve tube elements a...
