Carefully chosen full-color photographs of plants and a brief text present botanical characteristics for young readers. The author shows the wide variation in physical appearance in the plant world, while stressing that the function of plant parts is the same. Flowers produce seeds, often protected in a fruit; seeds develop into new plants. Examples are labeled and include familiar trees, shrubs, vines, grasses, vegetables, and house plants. Some photos give useful size clues--seeds resting on a human thumb or held in a hand; but the viewer will need prior experience with watermelon, kiwi, and yew berry to avoid concluding that they are the same size. No index. A satisfying introduction, vividly photographed.
