The process of development has been studied experimentally and otherwise. The studies and researches have highlighted certain significant facts or principles underlying this process. These are as follows: (i) Development follows a pattern: Peculiar of the species Development occurs in orderly manner and follows a certain sequence. For example, the human body cuts his molars before his incisors, can stand before he walks and can draw, a circle before he can draw a square.

First three divisions are vertical resulting into 8 celled stages. ADVERTISEMENTS: Fourth division is horizontal and unequal resulting into 16 blastomeres that are arranged in two tiers. 8 cells of lower tier are larger and are called macromeres. They form pinnacoderm in the adult. Other 8 cells of upper tier are smaller and are called micromeres. They form the choanoderm. Image Source: gbri.org.au Micromeres undergo subsequent division rapidly to produce numerous micromeres. They all acquire flagella at their inner ends, facing the blastocoel. ADVERTISEMENTS: Macromeres don’t undergo division but become somewhat rounded. The embryo is now called…
