4
Life Cycle • All living organisms go through stages in their lives. Example of stages: birth and dead. • In between these two stages many or few changes happen. • The process happens again in the next generation, and so on. • A life cycle describes all the stages in a living organism’s development from one generation to the next.
5
6
Reproduction • A cycle has no beginning and no end. • However, in living organisms, the stages include birth, and later, may include reproduction. • Reproduction is a process that a living organism uses to produce more of its own kind. • The changes between birth and reproduction varies from one organism to another.
7
BIRTH • Many kinds of animals are born or hatch from eggs looking like their parents (reptiles), others (like butterflies and frogs) do not look at all like their parents. • Those who do not look like their parents, will go through a series of morphological changes through time that will allow them to reach adulthood.
8
Growth and Development • After birth, humans go through infancy and childhood, followed by adolescence and finally, adulthood. • Many other kinds of animals develop into completely different forms as they grow through their life cycle, this is called metamorphosis. • Examples: tadpoles develop legs and lungs while becoming frogs; butterfly larvae form a cocoon, from where a butterfly arises.
9
How do animals reproduce? • All animals reproduce, but not through the same way. • Animals repoduce in two basic ways: sexually and asexually. • Sexual reproduction occurs when a sperm cell from a male and an egg from a female join to make a fertilized egg.
10
Asexual Reproduction • Asexual reproduction is much simpler, it doesn’t involve a sperm and egg. • Many invertebrates use asexual reproduction to produce offspring. • If a piece of a sponge falls off, it can grow into a new adult sponge, this is called regeneration. • Others like anemones and sea corals reproduce asexually by splitting in half. • Hydras, form a bud (budding) that falls off to become a new hydra.
11
Life Span – Life Expectancy • An animal’s life cycle may include birth, youth, old age, and death. • The time it takes for this to happen is called an animal’s life span. • Life expectancy is the average amount of time an individual animal might live according to the conditions around it. • Life expectancy is affected by conditions in the environment. Life span is not.

Teacher's Notes This class has been designed to cover the topics of Functions in Organisms III: Reproduction and Growth from Monday June 1st till Friday June 5th. For further knowledge about this topic: 1. Conduct a thorough search under the topic: Reproduction and Growth on the Web, books and magazines. 2. If findings are not specific, ask your teacher for suggestions.
