Alternation of generations (also known as metagenesis) is the type of life cycle that occurs in those plants and algae in the Archaeplastida and the Heterokontophyta that have distinct haploid sexual and diploid asexual stages. Each capitulum cell divides repeatedly to form 2-4 long, multicellular, branched or un-branched antheridial Filaments or sperinatogenous filaments (Fig. 6 A). 7 A, B). There are nine stages of development of the plant, as noticeable in figure 1. SmartDraw includes cycle diagrams templates you can customize and insert into Office. The life cycle begins with the penetration of the virus into the host cell. Where are the pollen grains formed in the flower? Structure- Spirogyra is a unbranched filament. 5 A). In some species of Chara e.g., C. nuda and C. braunii, the number of stipulodes at each node, is equal to number of primary laterals at that node, such species are called unitipulate. 8 A, B). The oospore inside contains a diploid nucleus and many oil globules in cytoplasm. 9 J-L). The amylum stars do detachment from plants develops into new Chara thalli. The three nuclei of basal cell degenerate gradually. Cycle diagrams are used for all sorts of processes and series of events. C. hatei grows trailing on the soil C. nuda and C. grovesii are found on mountains, C. wallichii and C. liydropitys are found in plains. The mature globule thus is made up of 8 curved shield cells, 8 elongated manubrial cells, 8 centrally located primary capitulum cells and 48 secondary capitulum cells. The amorphous bulbils are perennating structures, when the main plant dies under unfavorable conditions; these bulbils survive and make Chara plants on return of favourable conditions. Process Diagrams. 9 F). On nodes develop these following four types of appendages: The branches of limited growth arise in whorls of 6-20 from peripheral cells of the nodes of main axis or on branches of unlimited growth. The receptive spot is present at the upper part of nucule. Chara is aquatic attached to muddly or sandy bottom of the pools, lakes and slow flowing streams. That shows the changes in the execution status. The American Heartworm Society has updated the heartworm life cycle for use in the veterinary clinic and for pet owners. Chara is found mostly in hard fresh water, rich in organic matter, calcium and deficient in oxygen. The cells are multinucleate and contain many discoid chloroplasts. Chara often emits disagreeable onion like odour due to presence of sulphur compounds. In ferns, relative to the sporophyte the gametophyte stage of the life cycle is: small and ephemeral. The outermost eight cells enlarge laterally to form a curved plate of eight shield cells (Fig. Product Life Cycle Model PowerPoint Diagram. The nucule contains large amount of starch and oil.
