Aim #33: How do plants absorb light for photosynthesis?

Why is it called PHOTO …….SYNTHESIS? Photo …….. Light Synthesis…….. To make

Where is the energy coming from? 1) What color is sunlight?

2) Is white light really white? What do you see? 3) What colors make up white light? ROY G BIV

Review: Where does photosynthesis happen?

Review: In what organelles does it happen? CHLOROPLAST

4) Why are chloroplasts green? Chlorophyll – green pigment Traps ROY ___ BIV It reflects Green

5) How do chloroplast trap light energy? They have Chlorophyll- A green pigment that absorbs all colors Of white light, except_______

Absorption of Light by Chlorophyll a and Chlorophyll b VBGYOR Chlorophyll b Chlorophyll a Section 8-2 Figure 8-5 Chlorophyll Light Absorption Go to Section:

What happens when chlorophyll absorbs light energy? The light energy is transferred to electrons in the chlorophyll molecules. This raises the energy level of these electrons. These high energy electrons make photosynthesis work

6) Would a plant grow in green light? No…Why?

7) Is chlorophyll the only pigment? In the Fall we See the Others No

What colors do they absorb?

Pigments

Accessory pigments- a pigment that absorbs light energy of different wavelengths than chlorophyll and transfers it to chlorophyll-a molecules Carotenoids- pigments of colors other than green that function as accessory pigments

8) How can we separate these pigments? Chromatography Separates the mixture of pigments. Substances that have a strong affinity to the solvent travel further up the paper.

Chromatography- Pigments in Leaf

Let’s Review! 1)How do plants absorb energy from the sun? 2)What is a pigment? 3)Why does chlorophyll appear green? 4)What happens when chlorophyll absorbs light? 5)What are carotenoids?
