...Beetroot Cells The beetroot has high content of betalain. This betalain is the pigment responsible for the color of the beetroot. It is a red- purple pigment. Betalain is present inside the cell and it is protected by the tonoplast. Betalains are water-soluble and exists as internal salts in the sap vacuoles. The cell membrane is the most important part of a cell. It controls the movement of the molecules inside and outside of the cell. The cell membrane is linked to the inner organelles also. This cell membrane also acts like a wall to prevent the entry of the unwanted molecules. The cell membrane is made up of phospholipids... intact because of the non-covalent interaction of the...

The capability of stem cells to turn into any cell type that the body requires highlights their chief potential in treating diseases and repair the damaged organ or tissues. The ability of the stem cells to generate the desired organ is exploited to produce new skin, heart, muscle or liver tissue. These newly formed organs could be transplanted into the person devoid of any complications associated with transplantation rejection.
