Reading Passage:Osmosis and diffusion are of prime importance in living organisms, where they influence the distribution of nutrients and the release of metabolic waste products. Osmosis regulates water balance, while diffusion regulates the transport of other molecules. Living cells of both plants and animals are enclosed by a semipermeable membrane called the cell membrane, which regulates the flow of liquids and of dissolved solids and gases into and out of the cell. The membrane forms a selective barrier between the cell and its environment; not all substances can pass through the membrane with equal facility. Without this selectivity, the substances necessary to the life of the cell would diffuse uniformly into the cells surroundings, and toxic materials from the surroundings would enter the cell.Question:The diffusion of water across a selectively permeable membrane is called .....

Reading Passage:Osmosis and diffusion are of prime importance in living organisms, where they influence the distribution of nutrients and the release of metabolic waste products. Osmosis regulates water balance, while diffusion regulates the transport of other molecules. Living cells of both plants and animals are enclosed by a semipermeable membrane called the cell membrane, which regulates the flow of liquids and of dissolved solids and gases into and out of the cell. The membrane forms a selective barrier between the cell and its environment; not all substances can pass through the membrane with equal facility. Without this selectivity, the substances necessary to the life of the cell would diffuse uniformly into the cell’s surroundings, and toxic materials from the surroundings would enter the cell.Question:The diffusion of water across a selectively permeable membrane is called ____

A	pinocytosis.
B	osmosis.
C	osmotic pressure.
D	active transport.

Explanation:

Detailed explanation-1: -Why is Osmosis And Diffusion Important To Living Organisms? Osmosis and diffusion are both important to living organisms because they are both processes that allow molecules to move around. Osmosis is the diffusion of water molecules, and diffusion is the diffusion of all other molecules.

Detailed explanation-2: -Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products.
