Points out that plants differ in size, shape, and kinds of parts, yet similarities exist in both structure and function whether it be a one-celled or multicellular plant. Pictures through photomicrography cell, tissues, organ, and system organization. Shows germination through time-lapse photography and pictures life cycle of growth. Reviews that development energy comes from photosynthesis and respiration and tells how the organs of a green plant are related to these processes. States that the two phases in a plant's life cycle are vegetative and reproductive and mentions the structure involved in these processes. Shows a time-lapse photograph of vegetative growth. Points out that the other cells in the plant are dependent upon the chlorophyll containing cells just as are all animals and "greenless" plants.
