What is the main difference between amphibians and reptiles? a) Amphibians are tied to water for reproduction, while reptiles have amniotic eggs that can survive on dry land. b) Reptiles are tied to water for reproduction, while amphibians have amniotic eggs that can survive on dry land. c) Neither are tied to water for reproduction.

a) Amphibians are tied to water for reproduction, while reptiles have amniotic eggs that can survive on dry land.

Explanation:

Amnion is the membrane surrounding the fetus. Animals that posses amnion are termed as Amniotes. Amniotes are tetrapods (i. e descendants of four-limbed and backboned animals) that are characterised by having an egg equipped with an amnion, an adaptation to lay eggs on land rather than in water

Amphibians reproduce sexually with either external or internal fertilization. Amphibians do not produce amniotic eggs, so they must reproduce in water.

Unlike amphibians, in reptiles production of amniotic eggs takes place. The shell, membranes, and other structures of an amniotic egg protect and nourish the embryo. They keep the embryo moist and safe while it grows and develops in mos dry lands.

a) Amphibians are tied to water for reproduction, while reptiles have amniotic eggs that can survive on dry land.

Explanation:

reptiles = land

amphibians = water

Reptiles can reproduce on land, while amphibians need water to reproduce.
