Question 1

DNA copying

Difficulty: easySource: NCERT in-textTopic: dna-copying-and-variation

Why is DNA copying essential in reproduction?

1it transfers hereditary information2it prevents all variation3it replaces nutrition

Question 2

Variation

Difficulty: mediumSource: NCERT in-textTopic: dna-copying-and-variation

Variation is especially useful because it:

1guarantees every individual will live longer2may help some members survive environmental change3stops evolution

Question 3

Amoeba

Difficulty: easySource: NCERT Figure 7.1Topic: fission-fragmentation-regeneration-and-budding

Amoeba reproduces asexually mainly by:

1binary fission in any plane2longitudinal fission only3multiple fission only

Question 4

Plasmodium

Difficulty: easySource: NCERT Figure 7.2Topic: fission-fragmentation-regeneration-and-budding

Plasmodium produces many daughter cells at once by:

1budding2multiple fission3fragmentation

Question 5

Spirogyra

Difficulty: easySource: NCERT Activity 7.4Topic: fission-fragmentation-regeneration-and-budding

The usual asexual mode shown by Spirogyra is:

1fragmentation2budding3regeneration

Question 6

Hydra

Difficulty: mediumSource: CBSE 2023 five-mark familyTopic: fission-fragmentation-regeneration-and-budding

Which two processes are correctly linked with Hydra?

1budding and regeneration2fragmentation and binary fission3multiple fission and spore formation

Question 7

Difficulty: easySource: NCERT Activity 7.5Topic: vegetative-propagation-and-spore-formation

Which potato piece is most likely to sprout?

1a piece containing an eye or bud2any peel with no bud3a dry piece with no living tissue

Question 8

Rhizopus

Difficulty: easySource: NCERT Figure 7.6Topic: vegetative-propagation-and-spore-formation

Spores of Rhizopus are produced inside:

1sporangia2cotyledons3ovules

Question 9

Meiosis

Difficulty: mediumSource: CBSE 2025-2026 board familyTopic: why-sexual-reproduction

What prevents chromosome number from doubling every sexual generation?

1meiosis halves it in gametes2fertilisation destroys half the chromosomes3the zygote contains no DNA

Question 10

Anther

Difficulty: easySource: NCERT Exercise 3Topic: sexual-reproduction-in-flowering-plants

The anther contains:

1ovules2pollen grains3embryos

Question 11

Pollination

Difficulty: easySource: NCERT in-textTopic: sexual-reproduction-in-flowering-plants

Pollination is:

1fusion of gametes inside an ovule2transfer of pollen from anther to stigma3conversion of ovary into fruit

Question 12

Post-fertilisation

Difficulty: mediumSource: CBSE 2023-2026 board familyTopic: sexual-reproduction-in-flowering-plants

Which pair is correct?

1ovule -> fruit; ovary -> seed2ovule -> seed; ovary -> fruit3stigma -> seed; anther -> fruit

Question 13

Germination

Difficulty: easySource: NCERT Figure 7.9Topic: sexual-reproduction-in-flowering-plants

Which seed part forms the future root?

1plumule2radicle3cotyledon

Question 14

Testes

Difficulty: mediumSource: CBSE 2023-2026 board familyTopic: puberty-and-male-reproductive-system

Why are the testes located in the scrotum?

1sperm formation needs a temperature below normal body temperature2fertilisation occurs there3they store urine

Question 15

Seminal glands

Difficulty: mediumSource: NCERT in-textTopic: puberty-and-male-reproductive-system

Seminal vesicles and the prostate mainly:

1produce eggs2add nutritive transport fluid to sperms3cause menstruation

Question 16

Fertilisation site

Difficulty: easySource: NCERT/CBSE recurringTopic: female-reproductive-system-fertilisation-and-menstruation

Human fertilisation usually occurs in the:

1uterus2oviduct3vagina

Question 17

Placenta

Difficulty: mediumSource: CBSE recurringTopic: female-reproductive-system-fertilisation-and-menstruation

Which statement about placenta is correct?

1it provides exchange of nutrients, oxygen, and wastes2it produces pollen3it is the site of sperm formation

Question 18

Menstruation

Difficulty: mediumSource: NCERT Exercise 6Topic: female-reproductive-system-fertilisation-and-menstruation

Menstruation occurs when:

1an embryo implants2the egg is not fertilised and the prepared uterine lining breaks down3a sperm enters the oviduct

Question 19

Copper-T

Difficulty: mediumSource: NCERT in-textTopic: reproductive-health-and-contraception

Which statement is correct?

1Copper-T prevents pregnancy but does not protect against STIs2Copper-T blocks the vas deferens3Copper-T is a barrier worn on the penis

Question 20

Surgical contraception

Difficulty: mediumSource: CBSE 2026 official schemeTopic: reproductive-health-and-contraception
