Photosynthesis Flashcards
(12 cards)
What is the process of converting light energy to chemical energy in plants called?
Photosynthesis
Photosynthesis involves the transformation of light energy into chemical energy stored in glucose.
What is the chemical equation for photosynthesis?
6CO2 + 6H2O → C6H12O6 + 6O2
This equation represents the conversion of carbon dioxide and water into glucose and oxygen.
Where does photosynthesis primarily take place in plants?
In the leaves of plants
The leaves contain chloroplasts where photosynthesis occurs.
What is the role of chlorophyll in photosynthesis?
Absorbs sunlight and turns it into energy
Chlorophyll is a pigment found in chloroplasts that is essential for capturing light energy.
What is the effect of light intensity on the rate of photosynthesis?
Increases the rate of photosynthesis up to a certain point
Beyond a certain intensity, other factors may become limiting.
What is the relationship between CO2 concentration and the rate of photosynthesis?
Higher concentration leads to a higher rate of photosynthesis
Carbon dioxide is a critical reactant in the photosynthesis process.
How does temperature affect the rate of photosynthesis?
Higher temperature increases the rate of photosynthesis up to a certain point
Extreme temperatures can negatively impact the process.
What mineral ions are needed for plant growth and photosynthesis?
Nitrates, phosphates, potassium, magnesium
Each of these minerals plays specific roles in plant health and photosynthesis.
What is the function of nitrates in plants?
Contain nitrogen needed for amino acids and proteins
Nitrates are essential for growth and development.
What role do phosphates play in plants?
Needed for DNA, respiration, and growth
Phosphates are critical for energy transfer and genetic material.
What is the function of potassium in photosynthesis?
Helps enzymes needed for photosynthesis and regulates stomata
Potassium is vital for maintaining CO2 intake through stomata.
What is the role of magnesium in plants?
Needed for making chlorophyll
Magnesium is essential for the synthesis of chlorophyll, which is crucial for photosynthesis.
