(1) Reproduction is the process by which new individuals are produced by the parents. The process of reproduction ensures that a plant or animal species does not disappear from Earth. This process is very important in maintaining stability in the ecosystem and for the continuation of life on earth. Had there been no reproduction, all the species would have become extinct.(2)Fertilization is the biological process in which fusion of gametes of two different sexes, i.e., male and female takes place.Internal fertilization occurs in human being. One egg is released from the ovary and is transferred to the fallopian tube during each ovulation CYCLE. The sperm travels to the egg through the fallopian tube. Fertilization also takes place in the fallopian tube.(3)Zygote and Foetus are the two different terminologies, which refers to the developmental stages inside the mother’s womb or uterus.The zygote is the initial stage in baby development. It is also known as a fertilized ovum formed from the union of the sperm cell and the egg cell. Foetus refers to the final stage in baby development. An embryo is termed as the foetus in the beginning in the 11th week of pregnancy.(4)Asexual reproduction is a type of reproduction which does not involve the fusion of gametes or change in the number of CHROMOSOMES. The OFFSPRING that arise by asexual reproduction from a single cell or from a multicellular organism inherit the genes of that parent.Amoeba is a unicellular organism, and just like bacteria, it reproduces through binary fission. After replicating its genetic material through mitotic division, the cell divides into two equal-sized daughter cells. In this method, two similar individuals are produced from a single parent cell.Amoeba reproduces primarily by binary fission. However, a method known as multiple fission is adopted by the unicellular organism Amoeba to survive and reproduce under unfavourable conditions. When the conditions are unfavourable, Amoeba withdraws its pseudopodia and becomes almost round.(5)The embryo get embedded in the uterus of the female reproductive system.(6)Examples of metamorphosis include the tadpole, an aquatic larval stage that transforms into the land-dwelling frog (class Amphibia). Starfishes and other echinoderms undergo a metamorphosis that includes a change from the bilateral symmetry of the LARVA to the radial symmetry of the adult.(7)Internal fertilization is the process when the syngamy (union of male and female gamete) occurs inside the female body after insemination using copulation. In contrast, External fertilization is the syngamy outside the female body, that is in the outer environment especially in water bodies.HOPE MY ANSWER HELPED YOU!
