WebThe single root apical meristem in Azolla is tetrahedral in shape and there is a genetically determined limit of cell division as the meristem only divides 50-55 times. The study by Drs Hardham, Gunning and Hughes described all the cell lineages formed from the division of the root apical meristem. WebClose examination of an Azolla leaf reveals that it consists of a thick, greenish (or reddish) dorsal (upper) lobe and a thinner, translucent ventral (lower) lobe immersed in water.
