(1) IVF means In Vitro Fertilization (IVF) It then grows and upon becoming big it separates from the parent cell to have independent life as new yeast cell. This results in a small bulgingbud on the surface of parent cell. The parent cell produces two daughter nuclei by mitotic division. Yeast is unicellular fungus that performs budding. When favourable conditions reappear, they come out by breaking the cyst. Many amoebulae are formed which remain dormant inside the cyst. This is followed by cytoplasmic divisions. Inside the cyst, amoeba undergoes repeated nuclear division. Amoeba forms protective covering and becomes encysted. (c) Longitudinal binary fission: The plane of division is in length-wise direction as in Euglena.ĭuring unfavourable conditions when there is lack of food, multiple fission is shown by amoeba. (b) Transverse binary fission: The plane of J division is transverse, as in Paramoecium. (a) Simple binary fission: The plane of division is not definite, it can be in any direction due to lack of specific shape as in Amoeba. Prokaryotes, Protists and eukaryotic 5 cell-organelle like mitochondria and chloroplasts perform binary fission.īased on axis of fission there are three subtypes of binary fission. When there are favourable conditions and abundant food supply then the organisms undergo binary fission. It takes place either by mitosis or amitosis. (1) Binary fission: The process in which the parent cell divides to form two similar daughter cells There are different methods of asexual reproduction in different unicellular animals. Explain with examples types of asexual reproduction in unicellular organism. Under the effect of these hormones, glands of endometrium of uterus are activated and it becomes ready for implantation.Ī. Under the effect of Luteinizing hormone, fully grown up follicle bursts, ovulation occurs and corpus luteum is formed from remaining part of follicle. Ovarian follicle along with oocyte grows/regenerates under the effect of estrogen. Growth of follicles present in the ovary occurs under the effect of f ollicle stimulating hormone. are activated and it becomes ready for implantation. Under the effect of these hormones, glands of ……….

is formed from remaining part of follicle. Under the effect of …………., fully grown up follicle bursts, ovulation occurs and ……………. Growth of follicles present in the ovary occurs under the effect of ………….

(Luteinizing hormone, endometrium of uterus, follicle stimulating hormone, estrogen, progesterone, corpus luteum) Pollen grains are formed by division in locules of anthers.Ĭomplete the paragraph with the help of words given in the bracket: Body breaks up into several fragments and each fragment begins to live as a new individual. …………type of reproduction occurs without fusion of gametes.į. There may be some homologies but there is no similarity.Į. There is no similar gland in male and female reproductive system. In male and female reproductive system of human, …………. chromosome is responsible for maleness.Ĭ. In humans, sperm production occurs in the organ …………ī. There are no subtypes in the sexual reproduction.Ī.

Sexual reproduction occurs in two steps: First formation of haploid gametes by meiosis and then fertilization of these haploid gametes to form diploid zygote. New individual formed by this method is genetically identical with parents.ĥ. This reproduction occurs with the help of both mitosis and meiosis.Ĥ. Male and female parents are necessary for sexual reproduction.ģ. For asexual reproduction only one parent is necessary.Ģ. Reproduction that occurs due to fertilization of gametes is called sexual reproduction.Ģ. Asexual reproduction occurs in different individuals by various methods like binary fission, multiple fission, budding, fragmentation, regeneration, vegetative propagation, spore production, etc.ĥ. New individual formed by this method is genetically different from parents.ĥ. This reproduction occurs with the help of mitosis only.ģ.

Male and female parent are necessary for sexual reproduction.ģ. Reproduction that occurs with the help of somatic cells is called asexual reproduction.ġ.
