Butterfly Life Cycle
The life of a butterfly begins with an egg. An adult female butterfly lays many eggs. The eggs are laid on leaves that become food for the larvae when they hatch. larva A butterfly larva is called a caterpillar. The caterpillar hatches from the egg. It eats almost constantly in order to grow. The caterpillar molts (sheds its skin) as it grows. pupa A butterfly pupa is also called a chrysalis. It is encased in a hard covering and hangs upside down. Inside, wings and jointed legs are forming. The entire body is undergoing a transformation into an adult. These changes
are called metamorphosis. adult butterfly A full-grown adult butterfly emerges from the chrysalis. Adult butterflies mate in order to reproduce. After mating, the female butterfly lays eggs. The cycle begins again.

Bean Plant Life Cycle
seeds The life of a bean plant begins as a seed. The seeds are enclosed in a pod. Each seed contains an embryo, which is a tiny plant. The outer shell of the seed is called the seed coat. When a seed is placed in moist soil, a root breaks through its seed coat. This is called germination. seedling A young plant is called a seedling. As the roots grow down, a stem grows up. The seed coat breaks open and falls off. Two leaves open first. As the seedling continues growing, more leaves form. flowering plant When the bean plant is big enough, it will form flowers. Each flower contains an egg. Bees and other insects visit the flowers. As they do, they spread pollen from one flower to the next. This pollen fertilizes the egg. adult plant with seeds The fertilized eggs develop into seeds. In a bean plant, the seeds are enclosed in pods. The entire structure is called a bean. Beans grow from the flowers. People and other animals eat beans. Beans that are not eaten eventually dry out. The dry pods pop open, spilling the seeds. The cycle begins again.
