Final answer:
A low concentration in osmosis refers to a low concentration of solutes, indicating a hypotonic solution where water flows into the cell. Key concepts include hypertonic, isotonic, and hypotonic solutions, as well as dilute and concentrated solutions which are crucial for understanding cellular osmoregulation.
Step-by-step explanation:
In osmosis concentration, a low concentration can mean a low concentration of solutes. When referring to osmotic environments relative to a cell, there are key terms to understand:
- A hypertonic solution means the concentration of solute is greater than inside the cell, leading to a net flow of water out of the cell.
- An isotonic solution has an equal concentration of solutes inside and outside the cell, so water moves in and out at the same rate.
- A hypotonic solution means the concentration of solute outside the cell is less than inside, resulting in a net flow of water into the cell. This could cause the cell to swell and possibly burst (lyse).
- A dilute solution has a relatively small amount of dissolved solute compared to a concentrated solution which has a larger amount.
Osmosis involves the diffusion of water from an area of low solute concentration to an area of higher solute concentration. Understanding these concepts is essential for grasping how cells interact with their environment and maintain homeostasis.
