2017年2月13日 · The main function of the phloem is to transport nutrients from the source where they are produced (e.g. the leaves through photosynthesis) to the sink (e.g. flowers and fruits) where they are used.

Phloem (/ ˈ f l oʊ. 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.

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.

Phloem is the plant vascular tissue conducting foods made in the leaves during photosynthesis to other parts of the plant. Phloem is made up of different specialised cells known as sieve elements, phloem fibres, and phloem parenchyma cells.

2023年7月11日 · Function and Structure of Phloem. 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.

Phloem is defined as the specialized food conducting tissue of the plant cell, which assist the conductance of food (carbohydrates and amino acids) from the photosynthesized part (leaf) to the non-photosynthesized parts (like stem, flowers, buds, fruits, roots).

2024年2月27日 · Explore role of phloem in plant physiology. Learn how this specialized tissue transports essential nutrients throughout the plant and ensures proper growth. Understand phloem structure and function here.

2024年10月10日 · Explore how phloem supports plant nutrition and defense, highlighting its essential transport and protective roles. Plants rely on intricate systems to sustain growth and fend off threats. One such component is the phloem, a tissue responsible for transporting nutrients throughout the plant.

2024年9月20日 · Phloem is responsible for distributing organic nutrients, particularly sugars produced via photosynthesis, throughout the plant. Understanding the structure and function of xylem and phloem, as well as the mechanisms they employ, reveals fundamental processes critical to plant health and development.

Phloem is a specialised living tissue that transports amino acids and sugars from the leaves (source) to the growing parts of the plant (sink) in a process called translocation. This process is bi-directional. A source is a plant region that generates organic compounds, such as …
