Sexual reproduction is a complex and slow process but it offers many benefits from the perspective of survival. Sexual reproduction ensures variations and evolution; ensuring better chances of survival in changed conditions. Due to this, higher organisms have resorted to sexual reproduction in spite of...
diagram asexual reproduction does not involve the fusion of gametes, and therefore, the offsprings produced are genetically identical to the parent. the organisms produced by asexual reproduction are less diverse in nature. this type of reproduction is practised widely by unicellular organisms. the ...

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 rel...

Something unique that is observed is that even thoughplants,animals, andfungiare quite different from each other in aspects such as morphology, physiology, anatomy etc., all these organisms display sexual reproduction. The whole process also is quite elaborate and complex, involving many stages. Let...
Fertilization in flowering plants is unique among all known organisms, in that not one but two cells are fertilized, in a process called double fertilization. One spermnucleusin the pollen tube fuses with the egg cell in the embryo sac, and the other sperm nucleus fuses with the diploid endos...
Like many species of Anthozoa, octocorals are almost exclusively modular colonial marine inverte- brates that reproduce both sexually and asexually. As in all modular organisms, colony growth is a mode of asexual reproduction via budding of polyps. In addition, octocorals exhibit a diversity of ...
Sexual reproduction enables genetic exchange in eukaryotic organisms as diverse as fungi, animals, plants, and ciliates. Given its ubiquity, sex is thought to have evolved once, possibly concomitant with or shortly after the origin of eukaryotic organisms themselves. The basic principles of sex are ...
