Question

Select odd one out giving reasons:
Embryo, zygote, larva, foetus.

Answer 1

Larva:

1. The larva is the first or primary stage in the life cycle of an insect.
2. A larva is a worm-like organism that hatches from its egg.
3. The larval stage begins once the egg hatches.
4. As a result, the larvae are often known as young or baby insects.

Embryo, zygote, foetus:

1. After fertilization, the zygote, embryo, and foetus are all generated.
2. A zygote is formed by the union of a male and a female gamete.
3. The embryo is a stage of development that occurs in the egg or within the mother's uterus.
4. The foetus is an unborn child that develops and grows within the uterus.

Hence, the odd one out is Larva.
