Amoeba reproduces by budding. (k) Binary fission is a method of asexual reproduction. In such circumstances the value of sexual reproduction [music in] with its resultant diversity may actually weaken the dominance of an established group. (e) Egg laid after fertilization is made up of a single cell. External fertilization takes place in frog. Some plants can produce seeds without fertilization via apomixis where the ovule or ovary gives rise to new seeds. Pre-Fertilization Events: All the events of sexual reproduction that take place before the fusion of gametes are included in this category. A zygote is formed as a result of fertilization. Q. (l) Fertilization is necessary even in asexual reproduction. (False) (g) Fertilization is necessary even in asexual reproduction. (g) Fertilization is necessary even in asexual reproduction. Pre-Fertilization Events 2. 35. The events are: 1. Indicate whether the following statement is True (T) or False (F). Fertilization is necessary even in asexual reproduction. (False) (h) Binary fission is a method of asexual reproduction. External fertilization takes place in frogs. In sexual reproduction, two parents donate genes to their offspring through a process called fertilization.The resulting young receives a combination of inherited genes.In fertilization, male and female sex cells or gametes fuse to form a single cell called a zygote. ( ) (i) A zygote is formed as a result of fertilization. Asexual reproduction is all about exploiting a good niche. But in a changing environment, diversity means survival. Egg lay after fertilization is made up of a single cell. ( F ) (f) Amoeba reproduces by budding. Since sexual reproduction is more conducive to driving evolution than asexual reproduction, much more genetic diversity is available for natural selection to work on. (True) (i) A zygote is formed as a result of fertilization. 1. Answer: (a) True, sperm is a single cell with all the usual cell components. A new human individual developed from a cell is called gamete. ( F) (g) Fertilization is necessary even in asexual reproduction. Binary fission is a method of sexual reproduction. Post-Fertilisation Events. ( ) (j) … [Music out] Fertilisation 3. A zygote grows and develops by mitosis into a fully functioning individual. (k) Binary fission is a method of asexual reproduction. Answer (a) True (b) False (c) True (d) True (e) True (f) False (g) False (h) True (i) False (j) False (k) True (l) False (m) False. ADVERTISEMENTS: The following points highlight the three events that take place during the sexual reproduction. Fertilization is necessary even in asexual reproduction. Roots such as corms, stem tubers, rhizomes, and stolon undergo vegetative reproduction. ( T ) (i) A zygote is formed as a result of fertilization.

(b) False, A new human individual develops from a … Asexual reproduction produces individuals that are genetically identical to the parent plant. ( T ) … ( T ) (h) Binary fission is a method of asexual reproduction. (m) Cloning is a sexual reproduction method in mammals. Evolution can happen over time.
