An osteocyte, a star-shaped type of bone cell, is the most commonly found cell in mature bone tissue, and can live as long as the organism itself.[1] The adult human body has about 42 billion osteocytes.[2] Osteocytes have an average half life of 25 years, they do not divide, and they are derived from osteoprogenitors, some of which differentiate ...
A: According to the Infoplease website from Pearson Education, the biological importance of osmosis is that it facilitates the distribution of essential nutrients in the body and the excretion of metabolic waste products. Cells have semipermeable membranes, and osmosis makes it possible for liquid solvents to pass through these cell membranes.
Osmosis is actually a diffusion that takes place across a semi permeable membrane. For a clearer explanation, osmosis is the movement of water across a semi permeable membrane from an area of low solute concentration to an area of high solute concentration. Similar to diffusion, osmosis is a passive process. The result of osmosis is a separated two solutions of different concentrations. Water is the most suitable fluid to demonstrate osmosis. Osmosis is a vital process for every living organism in the planet and that includes humans and plants.
