Photosynthesis Flashcards
What is the primary function of photosynthesis?
To convert light energy into chemical energy in the form of glucose.
Which organisms primarily perform photosynthesis?
Plants, algae, and some bacteria.
What are the main components required for photosynthesis?
Light energy, carbon dioxide, and water.
True or False: Photosynthesis occurs in the mitochondria of plant cells.
False. Photosynthesis occurs in the chloroplasts.
What is the primary pigment involved in photosynthesis?
Chlorophyll.
Fill in the blank: The overall equation for photosynthesis can be summarized as 6CO2 + 6H2O + light energy → C6H12O6 + _____ .
6O2.
What are the two main stages of photosynthesis?
Light-dependent reactions and light-independent reactions (Calvin cycle).
Where do the light-dependent reactions of photosynthesis take place?
In the thylakoid membranes of the chloroplasts.
What is produced during the light-dependent reactions?
ATP, NADPH, and oxygen.
What is the main purpose of the Calvin cycle?
To convert carbon dioxide into glucose using ATP and NADPH.
True or False: Oxygen is a byproduct of photosynthesis.
True.
What role does water play in photosynthesis?
Water provides electrons and protons and is split to release oxygen.
Multiple Choice: Which of the following is NOT a product of photosynthesis? A) Glucose B) Oxygen C) Carbon Dioxide D) ATP
C) Carbon Dioxide.
What gas is taken in by plants during photosynthesis?
Carbon dioxide.
Fill in the blank: Plants convert light energy into chemical energy stored in _____ .
Glucose.
What is the role of NADP+ in photosynthesis?
It acts as an electron carrier, becoming NADPH.
True or False: Photosynthesis only occurs during the day.
False. While light is needed, some processes continue at night using stored energy.
What is the significance of the chloroplast’s structure in photosynthesis?
Its structure maximizes light absorption and facilitates the reactions of photosynthesis.
Which wavelength of light is most effective for photosynthesis?
Red and blue wavelengths.
What is the primary carbohydrate produced during photosynthesis?
Glucose.
Multiple Choice: What is the main purpose of chlorophyll? A) Absorb carbon dioxide B) Absorb light energy C) Release oxygen D) Produce glucose
B) Absorb light energy.
What type of energy transformation occurs during photosynthesis?
Light energy is transformed into chemical energy.
Fill in the blank: The light-independent reactions are also known as the _____ cycle.
Calvin.
What is the effect of increased carbon dioxide levels on the rate of photosynthesis?
It generally increases the rate of photosynthesis until other factors become limiting.
