Question

what are the different modes of asexual reproduction? Cite them with examples​

Answer 1

Answer:

Budding : a grouth on the body as a bud grows to from identical copy of patent EX:yeast. Spore formation: spores are produced in sporangium EX: rhizopus,mucor, bacteria, ferms and mosses. Regeneration: ability of organisms to give rise to new individual organisms EX:hydra,flatworm,tapeworm.

Answer 2

Asexual reproduction takes place by six different methods.

They are :

1. Fission
2. Budding
3. Spore formation
4. Regeneration
5. Fragmentation
6. Vegetative propagation

$\:$

1) Fission :

Single celled organisms split into two equal offsprings or more offsprings.

Ex :

• Paramoecium
• bacteria.

$\:$

2) Budding :

A growth on the body as a bud grows to form identical copy of parent.

Ex :

• Yeast
• Amoeba

$\:$

3) Spore formation :

Spores are produced in sporangium.

Ex :

• Rhizopus
• mucor
• bacteria
• ferms
• mosses

$\:$

4) Regeneration :

Ability of organisms to give rise to new individual organisms.

Ex :

• Hydra
• flatworm
• tapeworm

$\:$

5) Fragmentation :

New individual growth from a separate piece of parent organism.

Ex :

• Flatworms
• moulds
• lichens
• spirogyra

$\:$

6) Vegetative propagation :

a) Natural propagation :

i) Leaves :-

Eg : Bryophyllum

ii) Stems :-

Eg :

• Stolon - Vallisneria, Strawberry
• Bulbs - Onion
• Corms - Colacasia
• Tuber - Potato

b) Artificial propagation :

i) Layering :-

Eg :

• Nerium
• Guava
• Orange
• Rose

ii) Cutting :-

Eg :

• Rose
• Hibiscus
• Sugarcane

iii) Grafting :-

Eg :

• Sapota
• Guava
• Mango
