D) bi-axial elongation.
E) blastomere formation.

Question

Quizplus · Accepted Answer

Convergent extension is the term used to describe the morphogenetic process whereby cells extend themselves, making the mass of the cells narrower and longer. This process is crucial for a number of developmental processes, including the formation of the neural tube, the elongation of the body axis, and the development of the limbs.

Note: The other answer options are not accurate descriptions of this process. Induction refers to the process by which one group of cells influences the development of another group of cells. Elongational streaming and bi-axial elongation are not biological terms used to describe any specific morphogenetic processes. Blastomere formation is the process of cell division that occurs during early embryonic development.
