human embryo culture

Embryo Culture - Embryo mortality and seed failure associated with embryo development are most common reasons for failure of interspecific hybridization due to incompatability. In such instances, fertilization and zygote formation may not suffer but embr..

Protoplast Culture - 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..

. The callus is transferred to other medium that contains different hormones for differentiation to occur. This differentiated mass of tissue is called the embryoid which grows into the new plantlet. The plantlets are then planted in pots and then in the fields. Here are some terms used in cell and..

) 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 ..

Parthenogenesis and Tissue Culture - Parthenogenesis is a form of reproduction in which the ovum develops into a new individual without fertilisation. Natural parthenogenesis has been observed in many lower animals (it is characteristic of the rotifers), especially insects, e.g., the aphi..
