can we live without cells?
thats a simple question XD
Answer:
A. Water enters a plant by passing through the root cell membranes.
Explanation:
Osmosis is a kind of passive transport i.e. no energy input is required by the cell, that involves the movement of water across a semi-permeable membrane from a region of low solute concentration/high solvent concentration to a region of high solute concentration/low solvent concentration. The movement is usually facilitated by a difference in concentration gradient between the cell's membrane and the extracellular solution.
In this question, water from the soil enters into the root's cell via its cell membrane, which acts as the semi-permeable membrane. This movement must have occured because the solute concentration in the root's cell is higher than that of the soil, forming an osmotic gradient.
A normal range in adults is generally considered to be 4.35 to 5.65 million red blood cells per microliter (mcL) of blood for men and 3.92 to 5.13 million red blood cells per mcL of blood for women. In children, the threshold for high red blood cell count varies with age and sex.
