Morphogenetic determinants- transcription factors or messenger RNA's specify cell types, in this type of specification, the cell "knows" what it is to become very early and without interacting with other cells. ... Each of the blastomeres from a 2 cell embryo developed into a complete larva.

Where are morphogenetic determinants located?

In these embryos, morphogenetic determinants (certain proteins or messenger RNAs) are placed in different regions of the egg cytoplasm and are apportioned to the different cells as the embryo divides. These morphogenetic determinants specify the cell type.

What are the 2 types of morphogenesis?

Morphogenesis is brought about through a limited repertoire of variations in cellular processes within these two types of arrangements: (1) the direction and number of cell divisions; (2) cell shape changes; (3) cell movement; (4) cell growth; (5) cell death; and (6) changes in the composition of the cell membrane or ...
