Plant Parts

Plant Parts. Just like humans, plants have systems and subsytems that enable them carry out necessary processes. Each plant part - root, stem, leaf - has a specific role in keeping the plant alive through photosynthesis. Leaves (page 2) - main site of photosynthesis

Plants in Motion

Plants in Motion. Tropism in plants. Background. A stimulus is anything in the environment that causes a response in an organism. The response often involves movement either toward the stimulus or away from the stimulus. Plants respond to stimuli such as touch, light, and gravity.
