Transport sap
quizizz.com
- Unlike xylem (which is composed primarily of dead cells), the phloem is composed of still-living cells that transport sap. The sap is a water-based solution, but rich in sugars made by photosynthesis. These sugars are transported to non-photosynthetic parts of the plant, such as the roots, or into storage structures, such as tubers or bulbs.

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 material that makes up the vascu...
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 moved from the source, usually the leaves, to the phloem through active transport. The next step, translocation of the photoassim...
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 sink tissues where they are consumed or stored.
Xylem– One of two types of transport tissue within vascular plants, xylem is responsible for the transport of water from the roots to the leaves and shoots.Photosynthesis– The process which most plants use to convert energy from the sunlight, water and carbon dioxide into oxygen and carbohydrates.Photoassimilates– The biological compounds (usually energy-storing monosaccharaides) which are produced by photosynthesis.ATP– Adenosine triphosphate is the high-energy molecule that transports energy for metabolism within cells.1.

Phloem cells carry sugary water from the leaves to the rest of the plant. Phloem cells are alive. Phloem cells have companion cells with lots of mitochondria to provide energy.
Phloem (/ ˈfloʊ.əm /, FLOH-əm) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, [1] to the rest of the plant. This transport process is called translocation. [2] .
phloem, plant vascular tissue that conducts foods made in the leaves during photosynthesis to all other parts of the plant. Phloem is composed of various specialized cells called sieve elements, phloem fibres, and phloem parenchyma cells.
Jul 11, 2023 · Phloem transports organic nutrients, particularly sugars synthesized during photosynthesis, from the leaves to all other cells of the plant, including the roots. Phloem tissue is composed of sieve-tube elements, companion cells, phloem fibers, and phloem parenchyma.
