Q1: What is reproduction?

Reproduction is the biological process by which living organisms produce new individuals of the same species. It ensures continuity of species and is essential for life on Earth. Two main types: asexual and sexual reproduction.

Q2: Distinguish between asexual and sexual reproduction.

Asexual reproduction: single parent, no gamete fusion, offspring identical to parent (clones), examples: budding in hydra, fission in amoeba. Sexual reproduction: two parents, gamete fusion, offspring genetically different, examples: mammals, birds, most plants.

Q3: What is budding? Name the organism where it occurs.

Budding is asexual reproduction where a small outgrowth (bud) develops on parent body, grows, and detaches to form new individual. Occurs in: hydra, yeast, sponges. The bud is genetically identical to the parent.

Q4: What is binary fission? Give an example.

Binary fission is asexual reproduction where a single-celled organism divides into two identical daughter cells. Steps: cell nucleus replicates, cytoplasm divides, two genetically identical cells form. Example: amoeba and bacteria.

Q5: Explain the process of sexual reproduction in animals.

Sexual reproduction involves: 1) Male produces sperm (gamete) in testes, 2) Female produces ovum (gamete) in ovaries, 3) Fertilization: sperm fuses with ovum forming zygote, 4) Zygote develops into embryo, 5) Offspring born or hatched. Results in genetic variation.

Q6: What is the difference between oviparous and viviparous animals?

Oviparous: lay eggs outside body, embryo develops in egg with yolk, independent development. Examples: birds, reptiles, insects. Viviparous: fertilized egg retained in uterus, receives nutrition from mother via placenta, live young born. Examples: mammals like humans.
