ENERGY & LIFE

• Autotrophs get energy they need to produce food from the sun (or a light source)

• ATP stores energy for cell activities like active transport & movement within the cell

PLANT EXPLORATION…

Van Helmont:

• Plants need water to grow

Priestley:

• Plants produce oxygen (O2)

Ingenhousz:

• Plants need light to produce oxygen (O2)

Plants are green because of the pigment ______________.

(which absorbs light energy)

CHLOROPHYLL

•During the fall, the green chlorophyllgreen chlorophyll pigments are greatly reducedgreatly reduced revealing the other pigmentspigments.

•CarotenoidsCarotenoids are pigments that are either redred or yellowyellow.

Chloroplast

Structures & Function:

Locate the …

1. Thylakoids

2. Granum

3. Stoma

2 stages of photosynthesis:

1. Light-dependent reactions

2. Calvin Cycle (Light-independent)

Light Dependent Reactions

• Light absorbed by chlorophyll

(in Thylakoids)

• ADP converted to ATP

• Convert NADP+ to NADPH

(Electron Carriers)

• Produce Oxygen (O2) gas

Calvin Cycle

• CO2 enters from atmosphere

• Energy from ATP & NADPH used to convert 3-carbon molecule to higher energy

• Produces a single 6-carbon sugar molecule

Factors that affect the rate of Photosynthesis are…

• Availability of Water

• Temperature

• Intensity of Light

• Concentration of CO2

“World of Plants: Photosynthesis”Video Notes & Quiz

• Clear your desk except for the video notes page & pencil/pen

• Answer each question while watching the short video clip on photosynthesis

(There will be a video quiz at the end)
