Web2 days ago · Many plant and animal cells transition from canonical to non-canonical cell cycles during development, resulting in the formation of polyploid cells. Two types of non-canonical cell cycles exist: endoreplication, where cells increase their DNA content without entering M phase, and endomitosis, where cells enter M phase but exit prematurely. … WebThe cell membrane is selectively permeable.
