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 the diffusion of water across a cell membrane. It is an essential process in cell membrane functioning. Whether or not a cell contains a rigid cellular wall or not will determine how it reacts to hypotonic and hypertonic solutions.iological cell membranes are selectively permeable, which means that the ease and rate of small molecules passing through membranes vary widely. The plasma membrane regulates exchange of nutrients, oxygen, inorganic ions, waste products, and water. The cellular membraneâs molecular organization controls permeability.
