Apa itu fotosintesis?
Photosynthesis occurs only in the presence of water and soil nutrients.
Photosynthesis is the method by which plants absorb carbon dioxide from the soil.
Photosynthesis is the process of respiration in animals.
Photosynthesis is the process by which green plants convert light energy into chemical energy in the form of glucose.
What are the two main stages of photosynthesis?
Chlorophyll activation and glucose production
Light-dependent reactions and light-independent reactions (Calvin cycle)
Photosynthesis and respiration
Light absorption and energy storage
What happens during the light reactions?
Light energy is absorbed and stored as glucose.
Oxygen is consumed and carbon dioxide is released.
Chemical energy is converted into light energy and heat.
Light energy is converted into chemical energy (ATP and NADPH) and oxygen is released.
Where do the light reactions take place in a plant?
Thylakoid membranes of the chloroplasts
Cytoplasm of the cell
Nucleus of the cell
Mitochondrial membranes
What is produced during the light reactions?
ATP, NADPH, and oxygen
Fats and proteins
Chlorophyll and water
Glucose and carbon dioxide
What is the role of chlorophyll in photosynthesis?
Chlorophyll releases oxygen during photosynthesis.
Chlorophyll absorbs light energy for photosynthesis.
Chlorophyll converts carbon dioxide into glucose.
Chlorophyll is responsible for water absorption.
What happens during the dark reactions?
The dark reactions produce oxygen as a byproduct.
The dark reactions convert carbon dioxide into glucose using ATP and NADPH.
The dark reactions occur only in the presence of sunlight.
The dark reactions break down glucose into carbon dioxide.
Where do the dark reactions occur in a plant?
In the thylakoid membranes of the chloroplasts.
In the cytoplasm of the cell.
In the roots of the plant.
In the stroma of the chloroplasts.
What is the main product of the dark reactions?
Glucose
Oxygen
ATP
NADPH
How do light and dark reactions work together in photosynthesis?
Light and dark reactions work together by using energy from light reactions to fuel the dark reactions, which convert CO2 into glucose.
Dark reactions only happen at night without any light involvement.
Light reactions produce glucose directly without dark reactions.
Dark reactions occur independently of light reactions.
