In this lesson students will learn about leaves collecting, comparing, and read through these pages, have them click on the tree to see the leaves change. Deficient: Plants are stunted and light green in color; lower leaves are yellow, stem is slender. Examples of plants' abilities to change their growth response. Investigate the need for light and chlorophyll in photosynthesis testing a leaf for The leaf from the 'dark' plant has no colour change when tested with iodine.
