WitrynaProkaryotic cells are normally smaller than eukaryotic cells, with a typical size range of 0.1 to 5 μm in diameter. Prokaryotes are made up of a single cell, though they can pair up or cluster together to form … In some multicellular groups, which are called Weismannists, a separation between a sterile somatic cell line and a germ cell line evolved. However, Weismannist development is relatively rare (e.g., vertebrates, arthropods, Volvox ), as a great part of species have the capacity for somatic embryogenesis (e.g., … Zobacz więcej A multicellular organism is an organism that consists of more than one cell, in contrast to unicellular organism.
