Adhesion of male and female reproductive organs The formation of gametes by a reproductive organ formation of single cell during sexual reproduction by fusion of nuclei of male and female gamates. formation of single cell during sexual reproduction by fusion of nuclei of male and female gamates. 2 / 15 The ability of a cell to divide into several cells during reproduction in Plasmodium is called Budding vision Reduction division Binary fission multiple fission Multiple fission Repeated division of an organism to produce many daughter cells simultaneously. Repeated division of an organism to produce many daughter cells simultaneously. 3 / 15 Choose the precise statement(s) on budding in yeast from the following: A parent cell divides into two or more daughter cells and here the parent identity is lost In this the elongated nucleus divides to form two or more daughter nuclei. A bud arises from a particular region on a parent body After detaching from the parent body the bud grows into a new independent individual Budding in which a bud arises from a particular region on a parent body. And after detaching from the parent body the bud grows into a new independent individual Budding in which a bud arises from a particular region on a parent body. And after detaching from the parent body the bud grows into a new independent individual 4 / 15 In Rhizopus, tubular thread-like structures bearing sporangia at their tips are called Filaments Hyphae Rhizoids Roots In Rhizopus fungus, the fne thread-like structures that spread on the surface of bread are called hyphae In Rhizopus fungus, the fne thread-like structures that spread on the surface of bread are called hyphae 5 / 15 The characteristics transmitted from parents to ofspring are present in Cytoplasm Ribosome Golgi bodies Genes Genes are carriers of genetic information and are responsible for the transmission of characteristics from parents to offspring's. Genes are carriers of genetic information and are responsible for the transmission of characteristics from parents to offspring's. 6 / 15 Factors responsible for the rapid spread of bread mould on slices of bread are: Large number of spores Availability of moisture and nutrients in the bread Presence of tubular branched hyphae Formation of round shaped sporangia 1 2 1 And 2 1 and 3 Bread mould prefers damp/warm conditions with ample nutrient supply, on which air-borne spores land and germinate. Bread mould prefers damp/warm conditions with ample nutrient supply, on which air-borne spores land and germinate. 7 / 15 Example of unisexual fowers.
