Question

Which is incorrect about the process of gastrulation?

• A. Movement and rearrangement of cells
• B. Rapid division of cells by mitotic cell division
• C. Formation of three germinal layers
• D. Formation of archenteron

Answer 1

Answer: (B)

Rapid division of cells by mitotic cell division

• Cleavage is the process of rapid cellular division, which leads to the formation of the blastula.
  
• This blastula undergoes changes and forms the gastrula through gastrulation.
  
• During this process, there is no more cleavage and the cell grows in size as well as undergo morphogenetic movements and form 3 germ layers.
  
• The cavity of gastrula is known as the archenteron.
  

So, the correct option is 'Rapid division of cells by mitotic cell division'.
