WebThe female sex organ is flask-shaped and is termed carpogonium. Carpogonium possesses an elongated receptive organ named trichogyne. Spermatia are carried by water currents to trichogyne tips for effecting fertilization. The female sex organ remains attached to the plant and forms a new structure called carposporophyte. WebThe form and size of algae is highly variable, ranging from colonial forms like Volvox and the filamentous forms like Ulothrix and Spirogyra (Figure 3.1). A few of the marine forms such as kelps, form massive plant bodies. The algae reproduce by vegetative, asexual and sexual methods. Vegetative reproduction is by fragmentation. Weblular sexual organ is well known to have had its origin from a repro-ductive cell which produced asexual spores, and such may be called a sporocyst consistently with the other terms.
