WebIt is the food conducting tissue of vascular plants. Together with xylem, they form the vascular tissue system. The phloem composed of several types of cells among which some are living cells and some are dead. The term … Phloem is the complex tissue, which acts as a transport system for soluble organic compounds within vascular plants. The phloem is made up of living tissue, which uses turgor pressure and energy in the form of ATP to actively transport sugars to the plant organs such as the fruits, flowers, buds and roots; the other … See more Through the system of translocation, the phloem moves photoassimilates, mainly in the form of sucrose sugars and proteins, from the leaves where they are produced by photosynthesisto the rest of the plant. The sugars are … See more The structure of the phloem is made up of several components. Each of the components work together to facilitate the conduction of sugars and amino acids, from a source, to … See more 1. What is the main function of the phloem? A.

Webwhy can xylem transport water and minerals using dead cells, whereas phloem requires living cells? positive pressure, whether it be in the xylem when root pressure predominates, or in the sieve tube elements of the phloem, requires active transport. Most long distance transport in the xylem depends on bulk flow driven by negative pressure ... WebNov 22, 2024 · Xylem cells, which transport water and nutrients from the roots to the rest of the plant, are dead at functional maturity. Phloem cells, which transport sugars and other organic compounds from photosynthetic tissue to the rest of the plant, are living. The vascular bundles are encased in ground tissue and surrounded by dermal tissue. WebFeb 15, 2024 · Xylem consists of vessel elements, tracheids (conducting cells), and parenchyma (supportive tissue). The continuous vessels, or tubes, that compose the xylem are dead cells arranged from end to end. buick fresno
