Lab: Influencing the Rate of Photosynthesis Using the information from this experiment, explain what happens to the rate of photosynthesis on a cloudy day. What part of the experiment illustrated this? On a sunny day? Part of experiment that illustrated this?

Lab: Investigating the Rate of Photosynthesis When sodium bicarbonate comes in contact with water, the following reaction occurs: NaHCO 3 + H 2 O  NaOH + H 2 CO 3 How was the carbon dioxide used by the Elodea in the experiment? H2O CO 2

Electromagnetic Energy, Chloroplasts, Pigments, and Chromatography Section 8.1/8.2

Key Terms Energy –The ability to perform work. Visible Light –Form of electromagnetic energy that travels in waves. Pigment –Molecule that absorbs, reflects, or transmits different wavelengths of light.

Overview of Photosynthesis Two Stages: 1.Light Reactions 2.Calvin Cycle

Different forms of electromagnetic energy have different wavelengths. Wavelengths are measured in nanometers. Shorter wavelengths have more energy than longer wavelengths. What forms of electromagnetic energy exist?

Light energy can be: 1.Transmitted 2.Reflected 3.Absorbed What happens to light when it hits a surface?

Chloroplast Structure: a.Thylakoid b.Grana c.Stroma Pigments can transmit, reflect, or absorb different wavelengths of light. What happens to light when it hits a plant?

How do we know what pigments are present? Paper Chromatography: method for determining presence of pigments solvent moves up paper, carries pigments that have dissolved different pigments travel at different rates depending on how easy they dissolve and their attraction to the paper Why need to know pigments in a plant?
