In this article we will discuss about the process of reproduction in Cycas with the help of diagrams. Cycas is dioecious; but the male and female plants are indistinguishable until the appearance of male or female cone. The sex of individual plant is described to be determined by X- and Y-chromosomes. Male cone (Fig. 15.6A) is terminal, singly, on the [...]
In this article we will discuss about the anatomy of Cycas with the help of diagrams. Pinnae of Cycas leaves have a single mid-vein without any lateral veins but extending up to the lamina and quite prominent are the sheets of transfusion tissue (Fig. 15.3A, B), which acts as lateral conducting tissue in the leaflet without vein. A single vascular [...]
