Biology - Reproduction - Important Differences

Class 10 Biology - Reproduction - Important Differences (You Should Know)  #class10Science #eduvictors

Here is a list of important differences related to the Asexual mode and the Sexual Mode of reproduction, commonly asked in examinations.


Binary Fission vs Multiple Fission

Binary Fission Multiple Fission
The parent cell divides into two daughter cells. The parent cell divides into multiple daughter cells.
DNA copying occurs once. DNA copying occurs many times.
e.g. Amoeba e.g. Plasmodium (Malarial Parasite)

Pollination vs Fertilisation

Pollination Fertilisation
Pollination refers to the process of transfer of pollen grains from anther to the stigma of the same flower of a different flower of the same species. It refers to the fusion of male gamete and female gamete to form a zygote.
After pollination, the next step is fertilisation. It's a physical activity. After fertilisation, seed formation takes place. It's a biochemical activity.

Reproduction in Unicellular Organisms vs Multicellular Organisms

Unicellular Organisms Multicellular Organisms
Simple cell division. Lower organisms, simple cell division. Mostly gamete formation.
Binary Fission and Multiple Fission In asexual mode supports budding, fragmentation and regeneration.
e.g. Amoeba, Bacteria Planaria, Magno Tree, Human beings

Asexual Reproduction vs Sexual Reproduction

Asexual Reproduction Sexual Reproduction
Only one parent is involved. Two parents are involved.
No fusion of DNA is involved. Zygote formation is due to the fusion of DNAs.
Less Variation. Offsprings are almost identical to parents. More variation, offsprings similar to parents.

Budding in Hydra vs Budding in Yeast

Budding in Hydra Budding in Yeast
Buds are detached from parent body. Buds may remain attached to the parent body, thus forming a chain.
Multicellular buds Unicellular buds

Leishmania Fission vs Amoeba Fission

Leishmania Amoeba
Binary Fission occurs in definite orientation in relation to its whip-like structure. Binary fission occurs in any orientation/axis of division.

Self-pollination vs Cross-pollination

Self-pollination Cross-pollination
Transfer of pollen from anther to the stigma of the same flower. Transfer of pollen from the anther of one flower to the stigma of another flower on a different plant of the same species.

Reproduction vs Regeneration

Reproduction Regeneration
New individuals are formed either by asexual mode or sexual mode of reproduction. New organisms develop from the body part in certain organisms.

Budding vs Spore Formation

Budding Spore Formation
Asexual mode of reproduction where a bud develops as an outgrowth of a body. e.g. Yeast, Hydra. Tiny blob-like structures called sporangia to develop in organisms. e.g. Rhizopus

Male Gamete vs Female Gamete

Male Gamete Female Gamete
Produced in large numbers. In internal fertilization (humans), only one gamete is produced at a time.
Smaller in size and motile Big in size as they have food reserve and non-motile.

Human Male Urethra vs Human Female Urethra

Human Male Urethra Human Female Urethra
Common passage for urine and semen (sperms) Passage for urine only.
