Biological Reproduction Questions

Multiple choice

Ball of cells-movement-specialisation is a sequence of events seen in

  1. fragmentation

  2. regeneration

  3. multiple fission

  4. sexual reproduction
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ball of cells-movement-specialisation is a sequence of events seen in regeneration. The cells of cut part of the body divide rapidly to form a ball of cells. These cells move to their proper places where they become specialised to form different types of tissues.

Multiple choice

What is the method of reproduction in bees and wasps?

  1. Thelytoky parthenogenesis

  2. Arrhenotoky parthenogenesis

  3. Polyembryony

  4. Viviparity

  5. #

B Correct answer
Explanation

In arrhenotoky parthenogenesis, males develop from unfertilised eggs. This method of reproduction is seen in bees and wasps.

Multiple choice

Match the following methods of reproduction shown in the respective organisms.

 
1. Spirogyra a. Budding
2. Plasmodium b. Multiple fission
3. Yeast c. Binary fission
4. Paramecium d. Breaking up of filaments into smaller bits

  1. 1 - d, 2 - c, 3 - b, 4 - a

  2. 1 - a, 2 - b, 3 - d, 4 - c

  3. 1 - d, 2 - b, 3 - a, 4 - c

  4. 1 - d, 2 - c, 3 - a, 4 - b

  5. None of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Yes, it is correct. Spirogyra can reproduce both sexually and asexually. Spirogyra reproduces asexually by filaments breaking into smaller bits. Plasmodium reproduces by multiple fission. Yeast shows budding and paramecium reproduces by binary fission, when it reproduces asexually.

Multiple choice

Which of the following is not a property of asexual reproduction?

  1. It is the simplest method of reproduction.

  2. No sex cells are involved.

  3. Only one parent is needed to produce a new organism.

  4. The young one produced is not an exact copy of its parents.

  5. In this, a part of the parent organism separates off and grows into a new organism.

D Correct answer
Explanation

This is the correct option as this is not a property of asexual reproduction.
