Gene Expression. Totipotent Cells are undifferentiated cells‚ such as embryonic stem cells‚ that are not yet defined in their function. In animals‚ stem cells are totipotent. Plants have far more types of totipotent cells (Think of how you can make cuttings of plants‚ and grow an entirely new plant‚ given the right conditions?) Cells loose totipotency‚ as‚ with age‚ different genes are swtiched on/off. When certain genes are switched of‚ they are not translated to produce polypeptides‚ meaning
