In reproduction, we can get 2 types of organisms
- Babies Similar to Adults
- Babies Completely Different To Adults
Let's look at both of them
Babies are Similar to Adults
Example
In Human Beings,babies and adults have same body parts
Babies are Completely Different to Adults
Example
Tadpoles(Baby frog) look completely different from adult frog
They change from tadpole(larva) to adults by process called metamorphosis
What is Metamorphosis?
The transformation from larva (immature form) into adult is called metamorphosis
Larva and Adult look completely different from each other
Example -
Frog, Silkmoth
Example 1 - Metamorphosis in Frog
Egg of a frog develop into immature form called tadpoles
These tadpoles develop into adult frog
So there are 2 stages
- Hatching of egg to form tadpole
- Growth of tadpole into mature frog
Note:
Tadpole and frog look completely different from each other
Example 2 - Metamorphosis of Silk Moth
Egg of silkmoth develops into Caterpillar(larva)
Larva develops into pupa
This pupa develops into silkmoth
Note:
Tadpole and frog look completely different from each other
