Photosynthesis & Global Productivity

Print this and bring to discussion.

Objectives

At the end of this lesson, you should be able to:

ENERGY FLOW

1. describe the path of energy as it enters as light and passes through photosynthesis to form carbohydrates. Include these terms:

Light
Electron flow
Chlorophyll a

NADP+
Carbohydrates
Chlorophyll b
NADPH
ATP
Accessory pigments
Hydrogen Ions
ADP & Pi
Carotenoids

THE PROCESS

2. reproduce the general formula for photosynthesis and indicate the source for each of the elements in the raw materials and products.

FORM AND FUNCTION

3. draw and label a simple diagram of a chloroplast. Indicate in your diagram the location of the light-dependent reactions and the Calvin-Benson cycle.

ENVIRONMENT

4. explain how these environmental factors affect photosynthesis.

Temperature
pH

Light intensity
Drought
Light quality
Wind
CO2
Humidity

5.  explain how soil fertility can limit photosynthesis and crop productivity.

6.  predict the relative productivity of ecosystems.
