Plant Senses
• How do plants interact with their
environment?
– Touch
• Light: through chemicals that tell the plant
where light is and collect light for
photosynthesis.
• Does anyone know what photosynthesis is?
Chromatography
• We are going to use chemicals to separate the
different pigments from within a leaf.
• Follow the instructions of your leader.
