Define <\/b>binary <\/b>fission<\/b>. <\/b><\/p>\n A<\/b>nswer:<\/b><\/p>\n Binary fission means division into two. It is the simplest and most common method of asexual reproduction. It occurs in prokaryotes, many unicellular eukaryotes e.g. protozoa and some invertebrates.<\/a><\/p>\n Q4<\/b>. <\/b>What <\/b>is <\/b>Fragmentation? <\/b><\/p>\n A<\/b>nswer:<\/b><\/p>\n The type of asexual reproduction in which the organisms break up into pieces. For example, planarian breaks into 8-9 pieces instead of two. <\/span><\/a><\/p>\n Q5<\/b>. <\/b>Def<\/b>in<\/b>e <\/b>Budding<\/b>. <\/b><\/p>\n A<\/b>nswer:<\/b><\/p>\n It is the type of asexual reproduction in which a bud develops as a small outgrowth on parents body. For example, in yeast, a small bud is formed on one side of body of cell. The nucleus of cell divides and one of the nucleus is passed on to bud and form new cell. <\/span><\/a><\/p>\n Q6<\/b>. <\/b>Differentiate <\/b>between <\/b>spore <\/b>and <\/b>endospore<\/b>. <\/b><\/p>\n A<\/b>nswer:<\/b><\/p>\n Spore\u00a0<\/b><\/p>\n In <\/span>most <\/span>of <\/span>fungi <\/span>like <\/span>rhizopus<\/span><\/i>, <\/span><\/i>when <\/span>they <\/span>reaches <\/span>at <\/span>reproduction <\/span>age<\/span>, <\/span>its <\/span>body <\/span>cells <\/span>form <\/span>thick <\/span>walled <\/span>sacs <\/span>called <\/span>sporangia<\/span>. <\/span>Inside <\/span>each <\/span>sporangia<\/span>, <\/span>a <\/span>cell <\/span>divides <\/span>many <\/span>times and <\/span>forms <\/span>many <\/span>daughter <\/span>cells <\/span>called <\/span>spore<\/span>.<\/span><\/p>\n Endospore\u00a0<\/b><\/p>\n Under unfavourable conditions, some species of bacteria reproduce by forming spores \u0117.g., Clostridium and Bacillus species. Thick walled spores are formed inside bacterial cell. This is called endospores.<\/a><\/p>\n Q<\/b>7<\/b>. <\/b>Define <\/b>Parthenogenesis<\/b>. <\/b><\/p>\n A<\/b>nswer:<\/b><\/p>\n Type of asexual reproduction <\/span>in <\/span>which <\/span>an <\/span>unfertilized <\/span>e<\/span>gg <\/span>develops <\/span>into <\/span>new <\/span>offspring<\/span>. <\/span>For <\/span>example<\/span>, <\/span>some <\/span>fishes<\/span>, <\/span>frogs <\/span>and <\/span>insects <\/span>reproduce <\/span>by <\/span>means <\/span>of <\/span>parthenogenesis<\/span>. <\/span><\/a><\/p>\n Q8<\/b>. <\/b>What <\/b>is <\/b>Vegetative <\/b>propagation<\/b>? <\/b><\/p>\n A<\/b>nswer:<\/b><\/p>\n Whe<\/span>n <\/span>vegetative <\/span>parts <\/span>of <\/span>plants <\/span>i<\/span>.<\/span>e<\/span>. <\/span>the <\/span>roots<\/span>, <\/span>stems <\/span>or <\/span>le<\/span>a<\/span>ves <\/span>give <\/span>rise <\/span>to <\/span>\u0146ew <\/span>plants<\/span>, <\/span>the <\/span>process is called <\/span>vegetative <\/span>propagation<\/span>. <\/span><\/a><\/p>\n Q<\/b>9<\/b>. <\/b>What <\/b>is <\/b>Cutting<\/b>s<\/i><\/b>? <\/i><\/b><\/p>\n A<\/b>nswer:<\/b><\/p>\n In this <\/span>method<\/span>, <\/span>cuttings <\/span>may <\/span>be <\/span>taken <\/span>mainly <\/span>from <\/span>stems <\/span>or <\/span>roots <\/span>of <\/span>parent <\/span>plant<\/span>
