PHOTOSYNTHESIS LESSON 6

LIMITING FACTORS:

• CARBON DIOXIDE
• WATER
• SUNLIGHT
• CORRECT TEMPRATURE FOR ENZYMES

WHAT ARE ENZYMES?

• ENZYMES ARE A CATALYST
• THEY ARE LITTLE CHEMICAL FACTORIES THAT ARE USED TO SPEED UP CHEMICAL REACTIONS
• OPTIMUM TEMPRATURE IS BETWEEN 25-40 DEGREES CELCIUS

CONTROLLING LIMITING FACTORS:

• IN FIELDS THESE ARE DIFFICULT TO CONTROL
• THIS IS WHY WE USE GREENHOUSES
• MORE CONTROL OVER ALL THE LIMITING FACTORS;
• ESPECIALLY TEMPRATURE AND WATER SUPPLY

WHAT IS NOT A LIMITING FACTOR FOR PHOTOSYNTHESIS

1. WATER
2. SUNLIGHT
3. NUTRIENTS
4. CARBON DIOXIDE

WHAT IS A LIMITING FACTOR FOR PHOTOSYNTHESIS, ESPECIALLY IN WATER PLANTS

1. WATER
2. SUNLIGHT
3. NUTRIENTS
4. TEMPRATURE

WHAT IS A LIMITING FACTOR FOR PHOTOSYNTHESIS, ESPECIALLY FOR PLANTS IN GREENHOUSES

1. CARBON DIOXIDE
2. SUNLIGHT
3. NUTRIENTS
4. TEMPRATURE

WHAT IS A LIMITING FACTOR FOR PHOTOSYNTHESIS, ESPECIALLY FOR PLANTS IN NORTHERN EUROPE

1. CARBON DIOXIDE
2. SUNLIGHT
3. WATER
4. TEMPRATURE
