Sofia’s Lesson: All About Photosynthesis Flashcards
What is photosynthesis?
Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose.
Which pigment is primarily responsible for photosynthesis?
Chlorophyll.
True or False: Photosynthesis occurs only in the leaves of plants.
False.
What are the two main stages of photosynthesis?
Light-dependent reactions and the Calvin cycle (light-independent reactions).
Fill in the blank: The main products of photosynthesis are _____ and oxygen.
glucose
What is the chemical equation for photosynthesis?
6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
Which organelle is responsible for photosynthesis in plant cells?
Chloroplast.
What gas do plants take in during photosynthesis?
Carbon dioxide (CO2).
What is the role of sunlight in photosynthesis?
Sunlight provides the energy required to convert carbon dioxide and water into glucose and oxygen.
Multiple choice: What is produced as a byproduct of photosynthesis? A) Glucose B) Oxygen C) Both A and B
C) Both A and B.
True or False: Photosynthesis can occur without sunlight.
False.
What type of organisms perform photosynthesis?
Autotrophs, including plants, algae, and some bacteria.
Fill in the blank: The light-dependent reactions occur in the _____ of the chloroplast.
thylakoid membranes
What is the main purpose of the Calvin cycle?
To convert carbon dioxide into glucose using ATP and NADPH produced in the light-dependent reactions.
What role does water play in photosynthesis?
Water provides electrons and protons and is split to release oxygen during light-dependent reactions.
True or False: Only green plants can perform photosynthesis.
False.
What is the importance of photosynthesis to life on Earth?
Photosynthesis produces oxygen and organic compounds that are essential for the survival of most life forms.
Multiple choice: Which of the following is NOT a product of photosynthesis? A) Glucose B) Carbon Dioxide C) Oxygen
B) Carbon Dioxide.
What is the role of NADPH in photosynthesis?
NADPH acts as a reducing agent, providing electrons and hydrogen ions for the Calvin cycle.
Fill in the blank: The _____ is the part of photosynthesis that does not require light.
Calvin cycle
What is the significance of chlorophyll’s green color?
Chlorophyll absorbs light most efficiently in the blue and red wavelengths, reflecting green light.
True or False: The rate of photosynthesis can be affected by environmental factors.
True.
What are some factors that can limit the rate of photosynthesis?
Light intensity, carbon dioxide concentration, temperature, and water availability.
Multiple choice: Which of the following is a reactant in photosynthesis? A) Glucose B) Oxygen C) Water
C) Water.
