discuss the processes of cleavage gastrulation

Gastrulation is an important dynamic process in the development of the zygote which involves movement of cell masses from the surface of the blastula to their definitive positions in the embryo and their three primary germinal layers i.e., ectoderm, endoderm and mesoderm. ..

Cleavage is an unique embryological process which transforms the single fertilised egg cell into a sphere of closely aggregated multitude of cells. Immediately after fertilisation the fertilised ovum (egg cell) undergoes a series of cell divisions. These divisions are call..

All the events which change a zygote into a fully developed organism is called embryonic development. The entire process of development is called embryogenesis. Von Bear is called the "Father of Modern Embryology". Embryonic Development includes a definite series of fundamentally similar ..

. After fertilisation, the fertilised ovum trickles down into the uterus for implantation. Cleavage is the process which transforms the fertilised ovum into a sphere of closely aggregated cells. The fertilised ovum divides repeatedly in close succession to form blastomeres. ..

Acquired and Inherited Traits - What variations lead to a trait that is passed on to generations? Some of the formal theories on the process of micro-evolution are discussed in brief her..

Derivative of a Function - So far we have discussed the derivative of a function f(x) at a point 'a' which is in the domain of f. Suppose we want to find the derivative of the same function at a different point 'b', then we have to compute the derivative by repeating the same process..

The first law of thermodynamics is concerned with the conversion of energy from one form to another. It helps us to understand energy transformation in different chemical reactions. The basic point of the first law is that all physical and chemical processes take place in such a manner th..

Surface chemistry is the study of processes that occur at the interface of two bulk phases. The bulk phases can be of the type solid-gas, solid-liquid, liquid-gas and liquid-liquid. There is no interface between gases because of their complete miscibility. The bulk phase can be solutions ..
