In the process some of the mass of the hydrogen atoms is converted into energy in the form of light. The same process occurs in thermonuclear (fusion) bombs. In the Sun the process occurs in a controled manner. In a bomb it happens all at once in a big chain-reaction explosion.
Phloem. Definition. noun. A tissue in a vascular plant that functions primarily in transporting organic food materials (e.g. sucrose) from the photosynthetic organ (leaf) to all the parts of the plant.
Xylem and Phloem are found in the vascular tissue system in plant organisms. The xylem transports the mineral icons from the root to the rest of the plant, and the phloem carr â¦ ies the sugar and various other nutrients throughout the plant.ylem: tubes that brings water and minerals from the roots into the leaf. Phloem: tubes that usually move sap, with dissolved sucrose, produced by photosynthesis in the leaf, out of the leaf and to other parts of the plant.
