The movement of water molecules in and out of a cell is called osmosis.
Osmosis, or the diffusion of water molecules, is when water molecules flow in or out of a cell from high to low concentrations (down their concentration gradient). The ultimate goal of osmosis is to establish equilibrium between the cell and its outer environment.
Hope this helps!
Answer:
Both gene expression and DNA micro array study about the expression of gene during different stages of development.
Explanation:
The main purpose of gene expression studies is to determine the level of mRNA expressed at different stages of transcription in a tissue or at different stages of cellular development. If a gene is not “ON” during synthesis of RNA and protein, then the desired proteins are not produced. Such studies allow us to turn on such genes.
DNA microarray assays easily identify and determine the network of gene expression across the entire genome. The common application of DNA microarray include – mutation analysis and detection, assessment of gene cop, immunoassays etc.

To survive, desert plants have adapted to the extremes of heat and aridity by using both physical and behavioral mechanisms, much like desert animals. Plants that have adapted by altering their physical structure are called xerophytes. Xerophytes, such as cacti, usually have special means of storing and conserving water. They often have few or no leaves, which reduces transpiration.
