(3.10C) Life Cycles
The student is expected to investigate and compare how animals and plants undergo a series of orderly changes in their diverse life cycles such as tomato plants, frogs, and ladybugs.
Tomato plants are easy to grow and provide a good example of the flowering plant life cycle. More resources on plant life cycles can be found in this section.
The frog life cycle, as mentioned in the TEKS, is a typical example of amphibian development. Members of this group, which also includes salamanders and toads, spend the early part of their lives in water and their adult lives on land.
The ladybug, also known as the ladybird beetle, is mentioned specifically in the TEKS for grade three, so it is highlighted here. The life cycle of a ladybug is an example of complete insect metamorphosis, with four stages: egg, larva, pupa, adult.
