When an undifferentiated stem cell fuses with a mature differentiated cell, the resultant cell can retain the mature cell phenotype. Cell fusion can promote the transmission of viruses. MjRkNTQyZmE4NGE5MDk4ZDcwMmJjMmRiMDI5NjcxODVlNjg0MDZjZDE2ZDYw Fission, in biology, is the division of a single entity into two or more parts and the regeneration of those parts to separate entities resembling the original. b : zygote. Fusion is the process of combining two or more things together into one. -----BEGIN REPORT----- Cell fusion definition, the merging of two or more cells into a single cell. Binary fission is a type of asexual reproduction where a single living cell or an organelle grows twice its size and then splits into two identical daughter cells, where each of these daughter cells has the potential to grow into the size of the original cell or organelle. 2.
