How is it that your body with all of its specialized organs developed from a single cell? Scientists are exploring how gene expression patterns and their timing regulate cell differentiation.

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.

These are found in an early embryo. These cells are able to divide continuously. Embryonic stem cells are pluripotent. This means that all of the genes in an embryonic stem cell can be expressed ...
