Text SolutionText solutionverified iconVerified

Coelom is a fluid-filled space between the body wall and gut wall and lined by mesoderm on all of its sides. The presence or absence of body cavity or coelom plays a very important role in the classification of animals. Animals that possess a fluid-filled cavity between the body wall and digestive tract are known as coelomates. Annelids, mollusks, arthropods, echinodermates, and chordates are examples of coelomates. On the other hand, the animals in which the body cavity is not lined by mesoderm are known as pseudocoelomates. In such animals, mesoderm is scattered in between ectoderm and endoderm. Aschelminthes is an example of pseudocoelomates. In certain animals, the body cavity is absent. They are known as acoelomates. An example of acoelomates is Platyhelminthes.

O (11) O ering plants DEVELOPMENT OF ANTHER AND MICROSPOROGENESIS The anther appears as outgrowth like structure in the initial stage which shows spherical or oval shaped structure. At this stage, it is a mass of meristematic cells which is surrounded by a single celled thick outer layer. This layer is known as epidermis. First of all vascular tissues are formed in middle region. Simultaneously group of cells which are located just below the epidermis in vertical rows of hypodermal region at the four corners become large. These cells are called archesporial cells. Archesporial cells divide periclinally to form primary parietal cells and primary sporogenous cells. Epidermis T. S. of young anther O OO OFO Archesporial cell Meristematic cells Tetrahedral Isobilateral (In dicots) (In monocots) Ano. of Differentiated primary parietal cells nd primary sporogenous calls V Tawall Primary parietal cells undergo further periclinal and anticlinal division to form series of 3-5 layers making the walls of the anther. i.e. endothecium, middle laye and tapetum. The primary sporogenous cells divide by mitotic divisions to form sporogeno cells or sporogenous tissue and later sporogenous cells differentiate im microspore mother cells. Each microspore mother cell or cell of sporogenous tissue divides to form fa haploid microspore or pollen grain by meiotic division or reduction division.
