The Frog Life Cycle Process Essay

In Biology, we know the term metamorphosis which is the transformation process of animal’s body structure from the immature one to the adult form. This transformation process is done through cell growth and differentiation. This process usually happens in some insect’s life, such as butterfly. But there’s also amphibian, like frogs, which is also do metamorphosis in their life cycle. Frogs have some phases in their life cycle, part of the metamorphosis, which is interesting to be learned. Frog’s life cycle begins from eggs.

The adult frog may lay a mass of eggs. Frog will lay their eggs in static water to keep it from destruction. Not all of the eggs would turn into a frog later; there are some chances the eggs died. According to allaboutfrogs. com, the dead eggs tend to turn white or opaque. After 10 days, the eggs will hatch. Then those eggs enter the next phase. On the next phase, the embryo in the egg will leaves its jelly shell and becomes tadpole. These tadpoles have a long tail and their body is covered with external gills. In Adipedia. om, it was said that after a few days, skin will grow over the external gills and they will be changed with gill sac to absorb oxygen.

They have tiny teeth and eat algae. Based on Wikipedia, for digesting the food, they use a relatively long, spiral-shaped gut. They will grow and have some transformation later. After 6 weeks, several of tadpole’s body parts have shown some changes. Its front legs are formed under the gill sac before the hind legs which are visible a few days later. At the same time, lungs are quickly formed. Because of the transformation of the digestive system, tadpoles’ diet change too.

They begin eat different diet, like dead insects. Tadpoles will soon grow and change into frogs (allaboutfrogs. org). By twelve weeks, tadpoles will become more like frog. The skin got thickened. Next, their mouth widens and they lose their gills. For a replacement, they develop a big jaw which is stated in instruct. neric. org. Their tail also becomes smaller and disappears, while the legs grow. These outer body transformations affect the neural networks inside their body. At this phase, their lung is mostly functioning especially while they live on land.

So, the tadpoles have turned into adult frogs and completed the full growth cycle. As you can see, frogs have some metamorphosis phases in their life cycle. The phases begin with masses eggs in the water that will produce tadpoles. Tadpoles grow legs and lung and soon turn into a young frog before they finally become adult frogs. Then, these adult frogs find their mates. The female will lay their eggs while the male fertilize them, and the whole process will begin again. This is all the frog life cycle, the metamorphosis process of this amphibian family.
