Solution : Differences between internal and external fertilisation Internal fertilization Fertilisation takes place outside the female’s body A large number of male and female gametes are released in the surrounding medium (like water). Organisms that use external fertilization to reproduce must either live in the water or return to the water for reproduction. As the …

Solution : The site of fertilisation in human being is Ampulla of the fallopian tube. Human fertilization is the fusion of a human egg and sperm, usually occurring in the ampulla of the fallopian tube.

Solution : Definition : “Budding is an asexual reproduction in which a new organism is formed from a bud of a parent organism. The new organism (bud ) remains attached to the parent organism till maturity” Organisms like Hydra and yeast reproduce by budding. Process of Budding in Hydra Organisms such as Hydra use regenerative …

Solution : Regeneration in Hydra Regeneration is the capacity of an organism to produce a new individual or organism from one of its body components. When a hydra’s body is divided into pieces, each portion of the body can develop into a full hydra; in other words, when a hydra is divided into pieces, the …

Solution : Regeneration : Definition “Regeneration is the growth of an entire organism from sections of the organism’s body that are accidentally cut after an injury.” These organisms include starfish, hydra, planaria, and others. Regeneration in Planaria: Planaria have the ability to regenerate new organisms from their body parts. Regeneration is the name given to …

Solution : Definition : “A fragment of the parent becomes a new being during the fragmentation process.” Multicellular organisms can divide or reproduce by fragmentation. But, it cannot be used by all multi-cellular organisms. Organisms with complex structures cannot undergo cell-by-cell division. This is because, in complex multicellular organisms, each set of cells has specialized …

Solution : Multiple fission Definition : ” The process of asexual reproduction in which many daughter cells are produced from the parent cell is called multiple fission.“ Process of Multiple fission i) The nucleus is repeatedly divided during this process to produce a large number of nuclei.ii) Each nucleus takes up a small amount of …

Solution : Binary fission in Leishmania Binary fission has a specific direction in Leishmania. A constriction in the cell membrane first appears after nuclear division. The middle of the dividing cell is when the membrane begins to grow transversely and inward. The cytoplasm divides into two equal pieces, each with a single nucleus. The daughter …

Solution : The process by which a parent cell divides into two daughter cells is known as binary fission.A single-celled organism is an amoeba. Process of binary division in Amoeba It starts the reproduction process after maturation, i) first of all, lengthens by dividing its nucleus and divided into two nuclei. ii) The body ( …
