Conidia Penicillium C. Offset Water hyacinth D. Rhizome Banana (NEET 2015) A. Sexual. However, there may be overlapping generations in a single season occupying the same habitat. A B. Vegetative reproduction occurs through fragmentation, asexual occurs through formation of spores and binary fission, whereas sexual reproduction takes place by fusion of two haploid gametes. Sargassum fusiforme polysaccharides, acidic water-soluble polysaccharides extract from Sargassum fusiforme, are mainly composed of alginic acid, fucoidan and laminaran. Reproduction and Establishment of Sargassum heterophyllum (Turner) C.Ag. Alginic acid is carboxyl-containing polysaccharide formed by joining β -D-mannuronic acid and α -L-guluronic acid through β -(1→4)/ α -(1→4) glycosidic bond. Which of the following pairs is not correctly matched? ADVERTISEMENTS: The following points highlight the three modes of reproduction in algae. These are commonly produced by .

They first appeared in late spring and peaked in summer as upright thalli of the previous generation withered. Additionally, S. agardhianum pneumatocysts have a terminal spine. Seasonal population dynamics of Sargassum fusiforme, one of the most important edible macroalgae in Japan, were studied. Recruits were mainly generated by vegetative reproduction at the margins of filamentous holdfasts. The modes are: 1.
