WebA) Prokaryotic cells have a plasma membrane composed entirely of protein. B) Prokaryotic cells lack a membrane-bound nucleus and other membranous organelles. C) Prokaryotic cells lack DNA, RNA, and ribosomes. D) Prokaryotic cells have cytoplasm that is bounded by a cell membrane. E) Prokaryotic cells have cytoplasm but lack a cell membrane. Centrioles are involved in the organization of the mitotic spindle and in the completion of cytokinesis. Centrioles were previously thought to be required for the formation of a mitotic spindle in animal cells. However, more recent experiments have demonstrated that cells whose centrioles have been … Meer weergeven In cell biology a centriole is a cylindrical organelle composed mainly of a protein called tubulin. Centrioles are found in most eukaryotic cells, but are not present in conifers (Pinophyta), flowering plants (angiosperms) … Meer weergeven The centrosome was discovered jointly by Walther Flemming in 1875 and Edouard Van Beneden in 1876.
