Question

5 difference between sexual and asexual reproduction

Answer 1

Asexual

It involves a Single parent

Sex organs are not formed

Zygote is not Formed

the new progeny arises from a single cell or a part of that plant

Examples - Budding in Hydra , Bacterial Fission

Sexual

Two parent are involved

Sex organ are formed

Zygote is formed due to the fusion of gametes

New progeny arise from Zygote

Example - Reproduction in Human Beings

Answer 2

Asexual Reproduction:

1. It occurs in lower invertebrates and lower chordates and plants with simple organisations.

2. It is always uni-parental.

3. Gametes are not formed.

4. No fertilization.

5. It involves only mitosis.

6. Daughter organisms are genetically identical to the parent.

7. Multiplication occurs rapidly.

8. Since there is no variation, so it does not contribute to evolution of the species.

Sexual Reproduction:

1. It occurs almost in all types of animals and mostly in higher plants.

2. It is usually bi-parental.

3. Gametes are always formed.

4. Fertilization takes place.

5. It involves both meiosis and mitosis.

6. Daughter organisms genetically differ from the parents.
