Answer:
Most plants absorb water through the roots. Land plants get almost all the water they need from the soil. The amount of water available in the soil varies according to its porosity and its degree of desiccation. A large proportion of water is retained by cohesion forces between the particles. When the water is in the roots it moves inside the plant through the xylem. The xylem is the transport system that carries water to the entire plant.
Explanation:
The xylem connects all parts of the plants (from the roots to the stems and from there to the leaves). The water in the xylem creates a gigantic chain of molecules that adhere to each other, just like they adhere to the xylem. For plants to transport water from roots to leaves and use it in other functions, other structures called stomata are required. Stomata are small pores in leaves that plants can open and close as needed. If they open, the water moves out of the stomata and evaporates into the air. This occurs because the water molecules diffuse, from the humid air inside the leaf, to the much drier air surrounding the leaf. The loss of water through the stomata together with the high cohesion of the water particles and the resistance of the root "stress" the water column. This causes the water potential of the roots to decrease and the surrounding water enters the plant.Each stoma is made up of two occlusive cells. When these cells are turgid, a hole opens between them; when the cells relax, the hole disappears. The turgor pressure depends directly on the inlet or outlet of the water. This movement, in turn, depends on the concentration of solutes within the cell.
Your answer is mitosis. all organisms undergo DNA replication growth repair and ect.mitosis is in which the cell is divided into two can replicate DNA to the other to produce a new cell
The elimination of metabolic waste in the pig is the same, as most mammals, but post-birth, it goes out from the ureter. The ureter is the duct by which urine passes from the kidney to the bladder or cloaca. For a fetal pig, as any other mammalian species, it goes through <span>umbilical cord, and then the mother's vascular system moves it back into her bloodstream and then metabolized in the kidneys.
