Understanding Life Cycles: Growth, Traits, and Development in Organisms

This chapter explores the concept of life cycles in various organisms, detailing specific types of growth, such as direct development and metamorphosis. It discusses how traits differentiate organisms and delves into heredity, illustrating how genes are transmitted from parents to offspring. Key stages of human life cycles are presented, alongside examples from the animal kingdom. The chapter also covers the unique developments of different species, including those that undergo molting, highlighting the processes that dictate growth and reproduction in the natural world.
