Key concepts: Reproduction (Class 9 Science)
Reproduction is the process by which living organisms produce new individuals of their own kind, and it is essential for the continuity of a species rather than the survival of an individual. This chapter contrasts asexual and sexual reproduction, then works through reproduction in flowering plants and in humans.
- Reproduction
- The production of new individuals of the same species. Unlike nutrition or respiration it is not needed to keep an individual alive, but without it a species dies out.
- Asexual reproduction
- Reproduction involving a single parent and no gametes. The offspring are genetically identical to the parent, so they are clones.
- Binary fission
- A single-celled organism such as Amoeba divides into two roughly equal daughter cells, each receiving a copy of the genetic material.
- Budding
- A small outgrowth on the parent grows, develops the parent's features and detaches, as in Hydra and yeast.
Class 9 Science Reproduction MCQs with answers
14 solved questions across the difficulty levels this chapter is graded on — answer and explanation shown for each. The remaining 76 are timed and scored when you sign in.
- Q1Easy
How many parents are involved in asexual reproduction?
A.ThreeB.TwoC.One✓ CorrectD.FourAnswer: C. One
Explanation: Asexual reproduction needs only one parent and no gametes, unlike sexual reproduction where two parents contribute gametes that fuse.
- Q2Easy
Reproduction that involves two parents and the fusion of gametes is called:
A.Asexual reproductionB.Sexual reproduction✓ CorrectC.BuddingD.FragmentationAnswer: B. Sexual reproduction
Explanation: Sexual reproduction needs two parents whose gametes fuse to form a zygote, unlike asexual methods such as budding or fission that need only one parent.
- Q3Easy
Binary fission is the method of reproduction in:
A.Amoeba✓ CorrectB.RhizopusC.HydraD.SpirogyraAnswer: A. Amoeba
Explanation: Amoeba splits its single cell into two identical daughter cells by binary fission; Rhizopus instead forms spores and Hydra reproduces by budding.
- Q4Easy
Budding is a method of asexual reproduction seen in:
A.AmoebaB.PlanariaC.Hydra and yeast✓ CorrectD.SpirogyraAnswer: C. Hydra and yeast
Explanation: In budding, a small outgrowth forms on the parent and detaches as a new individual — seen in both Hydra and yeast, unlike Amoeba which splits by binary fission.
- Q5Easy
Spore formation is a method of reproduction in:
A.HumansB.AmoebaC.HydraD.Rhizopus (bread mould)✓ CorrectAnswer: D. Rhizopus (bread mould)
Explanation: Rhizopus (bread mould) produces sporangia full of spores on upright hyphae, and these spores germinate into new fungal threads; Amoeba instead divides by binary fission.
- Q6Easy
Fragmentation as a means of reproduction is seen in:
A.YeastB.Spirogyra✓ CorrectC.AmoebaD.PlasmodiumAnswer: B. Spirogyra
Explanation: Spirogyra filaments break into fragments, and each fragment grows into a new filament — this is fragmentation, distinct from budding in yeast or fission in Amoeba.
- Q7Medium
In humans, fertilisation normally takes place in the:
A.UterusB.OvaryC.Oviduct (fallopian tube)✓ CorrectD.VaginaAnswer: C. Oviduct (fallopian tube)
Explanation: In humans, the sperm meets and fuses with the egg inside the oviduct (fallopian tube); the zygote only reaches the uterus afterward for implantation.
- Q8Medium
The fertilised egg (zygote) gets implanted and develops in the:
A.OvaryB.Uterus✓ CorrectC.CervixD.OviductAnswer: B. Uterus
Explanation: The zygote travels from the oviduct and implants in the thickened lining of the uterus, where it develops through pregnancy — not in the ovary, which only releases the egg.
- Q9Medium
The average length of the human menstrual cycle is about:
A.28 days✓ CorrectB.14 daysC.7 daysD.90 daysAnswer: A. 28 days
Explanation: The human menstrual cycle averages about 28 days from the start of one period to the next; 14 days marks roughly its midpoint, not its full length.
- Q10Medium
In a typical 28-day menstrual cycle, ovulation (release of egg) occurs around day:
A.1B.7C.14✓ CorrectD.28Answer: C. 14
Explanation: In a typical 28-day cycle, the egg is released from the ovary around day 14, roughly midway between one menstruation and the next.
- Q11Medium
The structure that connects the developing embryo to the uterine wall for nourishment is the:
A.OviductB.Placenta✓ CorrectC.CervixD.OvaryAnswer: B. Placenta
Explanation: The placenta is the disc-shaped structure anchoring the embryo to the uterine wall, exchanging nutrients and oxygen; the oviduct is only the earlier site of fertilisation.
- Q12Hard
Which sequence correctly describes the path of human reproduction?
A.Ovulation → fertilisation in uterus → implantation in ovaryB.Fertilisation in uterus → ovulation → implantation in oviductC.Implantation in ovary → ovulation → fertilisationD.Ovulation → fertilisation in oviduct → implantation in uterus✓ CorrectAnswer: D. Ovulation → fertilisation in oviduct → implantation in uterus
Explanation: The correct order is ovulation from the ovary, fertilisation of the egg in the oviduct, and implantation of the resulting embryo in the uterus — fertilisation never occurs in the uterus itself.
- Q13Hard
The placenta is important during pregnancy because it allows:
A.Production of eggsB.Storage of spermC.Exchange of nutrients, oxygen and wastes between mother and embryo✓ CorrectD.PollinationAnswer: C. Exchange of nutrients, oxygen and wastes between mother and embryo
Explanation: The placenta is a large, richly vascular interface that lets nutrients, oxygen and waste pass between mother and embryo; it plays no role in egg production or pollination.
- Q14Hard
Why are offspring of asexual reproduction usually identical to the parent?
A.Because they eat the same foodB.Because there is one parent and no mixing of genetic material from gametes✓ CorrectC.Because they live in the same placeD.Because two gametes fuseAnswer: B. Because there is one parent and no mixing of genetic material from gametes
Explanation: With only one parent contributing DNA and no gamete fusion to shuffle genes, asexual offspring are exact genetic copies of the parent, not because of shared food or habitat.
