Question

The term applied to a morphogenetic process whereby cells extend themselves, making the mass of the cells narrower and wider, is ______. A. convergent extension B. induction C. invagination D. involution

Answer 1

The term applied to a morphogenetic process whereby cells extend themselves, making the mass of the cells narrower and wider, is convergent extension.

Morphogenetic order is a process of differentiation through which an embryo will organize itself.

In the field of biology, a convergent extension can be described as a process through which tissues of an embryo extend or elongates themselves during the phase of embryonic development. Hence, option A convergent extension is correct.

Option B is not correct as induction is a kind of morphogenesis in which the morphogenesis of tissue is induced by genetic means.

Option C is not correct because during invagination an epithelial sheet of the cell will move inwards.

Option D is not correct because involution is the process by which an organ tends to shrink and not grow wide.
