Osmosis is a type of diffusion that, in biology, is usually related to cells. Diffusion is when molecules or atoms move from an area of high concentration to an area of low concentration. Osmosis is when a substance crosses a semipermeable membrane in order to balance the concentrations of another substance. In biology, this is usually when a solve...
Osmosis deals with chemical solutions. Solutions have two parts, a solvent and a solute. When solute dissolves in a solvent, the end product is called a solution. Salt water is an example of a solution; salt is the solute, and water is the solvent.
In biology, there are three different types of solutions that cells can be in: isotonic, hypotonic, and hypertonic. Different types of solutions have different impacts on cells due to osmosis.
Osmosis affects plant and animal cells differently because plant and animal cells can tolerate different concentrations of water. In a hypotonic solution, an animal cell will fill with too much water and lyse, or burst open. However, plant cells need more water than animal cells, and will not burst in a hypotonic solution due to their thick cell wa...
Osmosis is how plants are able to absorb water from soil. The roots of the plant have a higher solute concentration than the surrounding soil, so water flows into the roots. In plants, guard cells are also affected by osmosis. These are cells on the underside of leaves that open and close to allow gas exchange. When the plant’s cells are full of wa...
Diffusion– a process by which molecules move from areas of high concentration to areas of low concentration. Osmosis is one type of diffusion.Solution– a mixture made up of two or more substances where one substance, a solute, is dissolved into another substance, a solvent.Semipermeable– also known as selectively permeable, this means that only certain substances can pass through a barrier. Cell membranes are semipermeable.Cell– the smallest unit that makes up a living organism. It includes various different parts called organelles that have functions such as storing genetic material and making proteins and energy.1. When a cell contains a lower concentration of solute than the solvent surrounding it, that cell is said to be in what kind of solution? A. Hypertonic B. Hypotonic C.Isotonic 2. Isotonic conditions are ideal for which cells? A. Plant cells B. Animal cells C. Both D.Neither 3. What happens to an animal cell in a hypotonic solution? A. There is no ...
Sep 8, 2023 · Biology definition: Translation is the process of translating (converting) the transcript (genetic information) from the mRNA into a specific sequence of amino acids in the growing chain of a polypeptide. The three general steps of translation are initiation, translation elongation, and translation termination.
