B4- Photosynthesis And Limiting Factors Flashcards
What is the main product of photosynthesis?
Glucose and oxygen
Photosynthesis produces glucose using light energy.
What is the overall equation for photosynthesis in word form?
light + carbon dioxide + water → glucose + oxygen
This represents the process by which plants convert light energy into chemical energy.
What is the symbol equation for photosynthesis?
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
This equation illustrates the chemical transformation during photosynthesis.
List the five main uses of glucose in plants.
- Respiration
- Making cellulose
- Making amino acids
- Stored as oils or fats
- Stored as starch
Each of these uses plays a critical role in plant growth and energy storage.
What is the role of glucose in respiration?
Transfers energy from glucose
This energy enables the plant to perform vital functions.
Why is starch better for storing energy than glucose?
Starch is insoluble
This prevents cells from swelling due to water absorption, which would occur if glucose were stored.
What factors can limit the rate of photosynthesis?
- Intensity of light
- Concentration of CO₂
- Temperature
- Chlorophyll levels
Any of these factors can become limiting based on environmental conditions.
At what time is light usually the limiting factor for photosynthesis?
At night
During nighttime, the absence of light limits the process of photosynthesis.
In which season is temperature often the limiting factor for photosynthesis?
Winter
Cold temperatures can slow down or halt the photosynthesis process.
What environmental condition can limit CO₂ concentration affecting photosynthesis?
Warm and bright conditions
When conditions are optimal for light and temperature, CO₂ may become the limiting factor.
How can chlorophyll levels affect photosynthesis?
Low chlorophyll levels can reduce the rate of photosynthesis
Factors such as disease or nutrient deficiency can damage chloroplasts and lower chlorophyll production.
