HAPPYH:

I came across this question


Caterpillar was kept in a air-tight glass bottle. The question is: Would the caterpillar grow into pupa? Explain your answer.

My DD's answer is No. Caterpillar needs air, food and water to grow into pupa.

Is this answer correct? I thought the answer should be there is no air, food and water in the glass bottle.

Kindly share your views.

Thank you in advance.

I would answer it this way though...

No, the caterpillar will not grow into a pupa. There is insufficient air in the air-tight glass bottle and hence the caterpillar will die before it can grow into a pupa.

hi, all the options are wrong. all the mentioned animals moult in their young. so answer should be all of the above. the caterpillar moults several times before becoming a pupa, for cockcroach and grasshoppers, their nymphs have to moult in order to grow bigger. for mosquitoes, they moult about 4 times in the larva stage before becoming a pupa.

hope it helps.

Thanks for the replies. I think best thing I can do now is to clarify with DD’s teacher.
