Birth and growth


Different plants and animals take birth in different ways. Some plants grow from seeds. Some grow out of bulbs or cuttings or other parts such as leaves. Some animals give birth to young ones. Some animals lay eggs and young ones hatch from eggs. The young are sometimes very different from the adults, as for example the butterfly or a newly sprouting bean plant. Sometimes the young look similar to the adults, but also have many differences. The growth of each living being is unique.
