Yes we are going to learn about asexual reproduction.<\/p>\n<p>As there is only one parent involved, so the new born organisms has exactly same character as that of its parent (clone). Normally amitotic or mitotic type of cell division occurs. Rate of reproduction is high in this type of reproduction.<\/p>\n<p><a href=\"https:\/\/www.askiitians.com\/blog\/wp-content\/uploads\/2016\/08\/SR-1.jpg\"><img fetchpriority=\"high\" decoding=\"async\" class=\"alignright wp-image-9687\" src=\"https:\/\/www.askiitians.com\/blog\/wp-content\/uploads\/2016\/08\/SR-1.jpg\" alt=\"SR-1\" width=\"300\" height=\"260\" \/><\/a>You know asexual reproduction occur &amp; both plant &amp; animals. And yes! No fertilization occurs in here.<\/p>\n<p>Asexual reproduction occurs by several ways. Let\u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u201e\u00a2s learn J<\/p>\n<p><strong> 1. Fission<\/strong> &#8211; It\u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u201e\u00a2s of two type\u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u201e\u00a2s viz. binary &amp; multiple fission.<\/p>\n<ul>\n<li><strong>Binary fission<\/strong> is more like a normal cell division. It occurs in unicellular organisms. It is simplest type of asexual reproduction. Now guys see the image (Fig A). It can also explain you in a better way.<\/li>\n<\/ul>\n<p><a href=\"https:\/\/www.askiitians.com\/blog\/wp-content\/uploads\/2016\/08\/SR-2.jpg\"><img decoding=\"async\" class=\" wp-image-9688 alignleft\" src=\"https:\/\/www.askiitians.com\/blog\/wp-content\/uploads\/2016\/08\/SR-2.jpg\" alt=\"SR-2\" width=\"325\" height=\"276\" \/><\/a>Binary fission can be observed in bacteria, yeast &amp; euglena. \u00c3\u201a\u00c2\u00a0Binary fission is of three types viz. longitudinal, transverse &amp; irregular fission. Again the picture (Fig B) can itself explain you \ud83d\ude42<\/p>\n<ul>\n<li><strong>In Multiple fission<\/strong> (Fig C); Many organisms are formed from single organism. In certain unicellular organism, when there is unfavorable condition, cyst is formed around them. Later after what happen is; nuclear division occurs inside.<\/li>\n<\/ul>\n<p><a href=\"https:\/\/www.askiitians.com\/blog\/wp-content\/uploads\/2016\/08\/SR-3.jpg\"><img decoding=\"async\" class=\"size-full wp-image-9689 aligncenter\" src=\"https:\/\/www.askiitians.com\/blog\/wp-content\/uploads\/2016\/08\/SR-3.jpg\" alt=\"SR-3\" width=\"637\" height=\"196\" \/><\/a>Later on, each nucleus is surrounded by small amount of cytoplasm. When the cyst burst in favorable condition, all cells are released.<\/p>\n<p>This type of fission has been observed in amoeba, plasmodium etc.<\/p>\n<p><strong>2. Budding <\/strong>\u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u20ac\u0153 Bulb like projection appears from the body of any organism that is reproducing by budding. This bud divides and later on separates from the parent body and forms the new organisms. Budding mainly occur in yeast, hydra, sponges etc.<\/p>\n<p><strong>3. Fragmentation and regeneration<\/strong> \u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u20ac\u0153 An organism breaks into many parts and then each part forms a new organism. Regeneration is way of healing any particular part of body by cell division. \u00c3\u201a\u00c2\u00a0Fragmentation occurs in many organisms like sea star, fungi, plants, worms and annelids etc.<\/p>\n<p><strong><a href=\"https:\/\/www.askiitians.com\/blog\/wp-content\/uploads\/2016\/08\/SR-5.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignright wp-image-9685\" src=\"https:\/\/www.askiitians.com\/blog\/wp-content\/uploads\/2016\/08\/SR-5.jpg\" alt=\"SR-5\" width=\"353\" height=\"196\" \/><\/a>4. Sporulation (Fig E)<\/strong> \u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u20ac\u0153 I hope you are enjoying reading this ;). Well! Spores are gametic bodies here. They help in formation of new organisms. Reproduction occurs in them by spreading of spores which are formed in sporangia. In favorable condition, this sporangia burst and all spores are spread in air. Later on each spore is converted into new organism. This type of reproduction occurs in many organisms like fungi (mucor &amp; rhizopus) etc.<\/p>\n<p>You know spores are of two types viz. zoospores &amp; aplanospores.<\/p>\n<ul>\n<li><strong>Zoospores<\/strong> are motile as they have flagella.<\/li>\n<li><strong>Aplanospores<\/strong> are non-motile as they don\u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u201e\u00a2t have flagellar extensions.<\/li>\n<\/ul>\n<p><strong>5. Vegetative Propagation<\/strong> \u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u20ac\u0153 It\u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u201e\u00a2s a special type of reproduction in plants. It occurs by <strong>natural and artificial method.<\/strong><\/p>\n<p>In natural way, any of the part of plant is taken which is other than the sexual part of plant (flower) &amp; it helps in new plant formation.<\/p>\n<p>Artificial method includes cutting, layering &amp; grafting. \u00c3\u201a\u00c2\u00a0I think even this picture can explain the whole story in better way \ud83d\ude42<\/p>\n<p><a href=\"https:\/\/www.askiitians.com\/blog\/wp-content\/uploads\/2016\/08\/SR-6.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-9686 aligncenter\" src=\"https:\/\/www.askiitians.com\/blog\/wp-content\/uploads\/2016\/08\/SR-6-1001x1024.jpg\" alt=\"SR-6\" width=\"1001\" height=\"1024\" \/><\/a><\/p>\n<ul>\n<li>Layering is done in raspberries.
