Biological Reproduction Questions

Multiple choice

In the process of sexual reproduction ______.

  1. only males are needed

  2. both male and female are needed

  3. only females are needed

  4. only mitosis is involved

Multiple choice

  3. Transpiration

  4. Respiration

A Correct answer
Explanation
System
Function
Digestive system
Taking in complex food and using it in simple form by body
Respiratory system
Inhaling and exhaling air and utilizing it to meet energy needs
Circulatory system
Movement of blood to each and every part of body to provide nutrition
Excretory system
Removal of water materials from the body

So it is the respiratory system involved in the inhalation and exhalation of air. Whereas transpiration is loss of water from leaf surface and reproduction is a mode of giving birth to similar ones.

Multiple choice

Mucor shows

  1. isogamy

  2. anisogamy

  3. oogamy

  4. None of these

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Anisogamy is sexual reproduction by the fusion of dissimilar gametes. This is shown by mucor.

Multiple choice

Asexual reproduction requires

  1. two individuals

  2. two individuals of opposite sex

  3. one individual

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Asexual reproduction requires one individual.Asexual reproduction is a mode of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it is reproduction which almost never involves ploidy or reproduction without the fusion of gametes.

Multiple choice

When male differs from female in morphology, it is called

  1. heterogamy

  2. homogamy

  3. sexual dimorphism

  4. hermaphroditism
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

When male differs from female in morphology, it is called sexual dimorphism. This differentiation happens in organisms who reproduce through sexual reproduction, with the prototypical example being for differences in characteristics of reproductive organs.

Multiple choice

In sexual reproduction, there must be a union of

  1. one male and one female reproductive cell

  2. two male reproductive cells

  3. two female reproductive cells

  4. two male cells with two female reproductive cells
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In sexual reproduction, there must be a union of one male and one female reproductive cell.

Multiple choice

Most terrestrial animals reproduce by

  1. internal fertilisation

  2. external fertilisation

  3. dichogamy

  4. pollination
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Most terrestrial animals reproduce by internal fertilisation which takes place inside the female body.

Multiple choice

Zygote is produced during

  1. sexual reproduction

  2. asexual reproduction

  3. vegetative propagation

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Zygote is produced during sexual reproduction. It is a eukaryotic cell formed by a fertilization event between two gametes.

Multiple choice

Endogamy (self fertilisation) is observed in

  1. ascaris

  2. earthworm

  3. taenia

  4. honey bee
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Endogamy (self fertilisation) is observed in taenia,It involves the fusion of two types of gametes derived from the same parent (uni-parental) . It is a very rare process.
