1991. Robert W. Wood. Plant biology, or botany, is the science of plant cell growth and regeneration and how these processes influence other living things. This book introduces readers ages 8 through 13 to the ways in which we study and use plants for food, medicine, and manufacturing. These entertaining and educational projects can be completed easily, safely, and in a minimal amount of time. Fully illustrated, the experiments show readers how to: preserve a leaf collection, determine the age of a tree, grow a new plant from a leaf, build a minature greenhouse, sprout a potato, repot a plant, graft a plant, and more. Includes suggestions for planning a science fair project. 123 pages, soft cover.
