While divergence between X and Y sex chromosomes has been described in a growing number of angiosperm species2,3, investigations of what some consider to be less common ZW systems can shed new light on the dynamics and consequences of sex chromosome evolution. Since its discovery as the likely...
Though each species of angiosperm varies widely, from the largest oak tree to the smallest dandelion, the flower structure has recognizable parts that are specialized for specific functions. In general, angiosperms can be split up into three groups, depending on the structure of each species' ...

Structure of Microsporangium:A typical microsporangium appears nearly circular in outline. It is generally surrounded by four wall layers, viz. epidermis, endothecium, middle layers and tapetum. The outer three wall layers perform the function of protection and help in dehiscence of anther to relea...
