Match the following: 1. Paramecium a) 280 days 2. IVF b) Birds 3. Gestation period c) Test-tube baby 4. Internal fertilisation d) Budding 5. Yeast e) Binary fission

1-e) Paramecium and Amoeba reproduce by binary fission, where the parent cell splits into two halves, producing two new daughter cells. It is a type of asexual reproduction. 2-c) IVF ( in-vitro fertilisation) works by using a combination of medicines and surgical procedures to help sperm fertilise an egg to produce the zygote in a test tube. It is then implanted in the female uterus where it develops into an embryo. 3-a) The time starting from fertilisation of gametes until the birth of a foetus is known as the gestation period. It lasts for 280 days. 4-b) The male gametes of a bird are introduced into the body of the female bird which fuses with the egg to produce the zygote. Since the fusion of the gametes occurs inside the body, the fertilisation is called internal fertilisation. Birds are oviparous animals. 5-d) Yeast is a unicellular organism that belongs to the kingdom Fungi . It performs budding which is a type of asexual reproduction. A new organism develops from an outgrowth or bud. The bud develops and gets detached to become an independent organism. Even Hydra reproduces by the same method. 1. Paramecium e) Binary fission 2.
