Describe the effects of osmosis in plant cells

osmosis is responsible for the ability of plants roots to draw water from the soil.

Explanation: osmosis is simpliy the ability of a water to pass thourgh a semipermiable membrane from a region of low concentration to a regin of high concentration, so plants concentrates solutes in their root cells by active transport and water enters the roots though osmosis. Osmosis is also responsible for movement of gurd cells.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
