Protoplast is a cell without cell wall. In plants, the cells are invariably surrounded by thick cell wall made of cellulose and pectin. During the process of tissue culture and using it for crop improvement, cell wall acts as a barrier to induce mutations or some times to develop the call..

) which is activated to grow into separate organism by suitable mixture of cytokinins and auxins. The success in tissue culture depends upon a) the precision and length of asceptic condition b) source of explants c) compositions and concentrations of nutrients media d) time and dosage of ..

The process of attachment of the blastocyst (blastula) on the endometrium of the uterus is called implantation. It generally occurs on the seventh day after fertilisation, thus establishing pregnancy. After implantation, the endometrium undergoes profound changes and is called the decidua..

Many years ago, Frederick Steward and his co-workers cultured cells from carrot plants and induced some of them to develop into small embryos. Some of these embryos grew into whole plants. Today, researchers routinely regenerate crops, plants and many other plant speci..

. The plantlets are then planted in pots and then in the fields. Here are some terms used in cell and tissue culture. The cells/tissues of the plant used for culture is called the explant . The undifferentiated mass of cells obtained from the single cell is called the callus . T..

Cloning of Organisms - Two or more individuals with identical genetic make up formed from one parent by asexual reproduction are called clones. For example, daughter plants produced by strawberry runners and whole plants produced by tissue culture are clones. Similarly, the individuals fo..
