What does it mean by " Hyperhydricity " in tissue culture context?
829358
Hyperhydricity, or vitrification, is a physiological malformation affecting tissue culture-generated plants. This malformation is associated with excessive hydration and poor lignification and results in poor regeneration of plants.

Not too sure i can give a firm answer for this... see the website below for some good resources\n\nhttp://www.awionline.org/lab_animals/rhesus/Pho-ref.htm

A Hypotonic solution concentration is alway smaller then the compared medium. A Hypertonic solution is alway higher concentrated. That is just what the word means. It's latin. hyper stands vor above and hypo for below.\nI hope I could help you\nGreatings Dr.Seuss

Yes, osmotically refers to the water and salt ion gradients inside and outside a cell's, or any selectively permeable, membrane. There are three states of osmotic condition. Isotonic = similar inside and outside.  Hypertonic where there is more salt ions outside fo the cell.  Water osmotically diffuses out of the cell.  This leads to cellular creanation Finally, hypotonic where there is more salt ions inside the cell  Water osmotically diffuses into the cell.  This is osmosis leading to cytolysis.

Nope. Hypertonic=draws water in. Hypotonic=excess water. Isotonic=balanced. I remember it because "hyper" means a lot, as in a lot of molecules to attract water.

I'm guessing it has something to do with being hydrophobic, and it's method for infection within a cell.

You need to define "viable and non-viable" cells....if DNA is still present for reconstruction of crime or accident...then the cells are viable.\n\nIf you are wanting to grow cells in a medium..then if the cell walls are intact and no damage to the cell structure has occurred...then the cell will be viable...\n\nmaybe this will help\n\n\nGood luck

What class was this in? What grade level? What text were you using?  I may be able to help you if I know the context in which the question was raised. I have a feeling that I am not getting all the information you had. Please tell me and maybe I can help. I am an old chemist and microbiologist.

Cytotoxicity is the quality of being toxic to cells. Examples of toxic agents are a chemical substance or an immune cell.\n\nCytotoxicity can be measured by the MTT assay.\n\nCytotoxic activity is the action that the substance takes that makes it toxic to cells

Yes mostly. Its kind of an ongoing process. So the bringing in of water will then diffuse which is basically osmosis (water moving from a higher to a lower concentration). Which would take it to the Xylem were transport would occur. Turgidity and flaccidity are states of the cell and are not really processes. In a well watered root there should be no flaccid cells as this only occurs in the absence of water or the presence of excessive solutes. Most cells should be turgid most of the time.
