Let’s look at some life cycles in nature!Here is a picture of the life cycle of a tomato plant.Would this be considered a complete or incomplete metamorphosis?
Here is the life cycle of a frog.Is this life cycle a complete or incomplete life cycle?Remember, look at the baby?Does it look like the adult??
Let’s compare the life cycle of a butterfly, beetle, radish, lima beanWhat do you notice?
It is very important that you know the difference between complete and incomplete metamorphosis of insects.
Your teacher is going to give you alist of Insects on a lab sheet.One by one you will look at pictures ofthe life cycles of each insect that islisted on your sheet.You are to determine whether the life cycleiscomplete or incomplete.Then, you are to write“How you Know”what type of life cycle each insect goes thru.******Complete: The baby does not look like the adult.Incomplete: the baby looks like the adult
