Consequently, I chose to study the effects of lithium on cell differentiation in amphibian embryos for my PhD, with the hope of discovering its molecular mechanism. Chemical embryology appeared to ...

Plant cells are also able to become longer as they grow. This process is called cell elongation and occurs throughout the plant, not just in the meristems. Cell elongation does not occur in animals.

When cells express specific genes that characterise a certain type of cell we say that a cell has become differentiated. Once a cell becomes differentiated it only expresses the genes that produce ...
