Q1 The author’s main purpose in the passage is most likely to: (A) criticize outdated medical
practices (B) explain the process of photosynthesis (C) persuade readers to eat more vegetables
(D) describe the history of plant biology
Answer: (B) explain the process of photosynthesis
Rationale: The passage systematically describes how plants convert sunlight, carbon dioxide,
and water into glucose and oxygen — a clear explanatory purpose.
Q2 Which sentence from the passage best supports the idea that plants are the foundation of most
food chains?
Answer: ―Plants convert sunlight, carbon dioxide, and water into glucose and oxygen, providing
energy for nearly all life on Earth.‖
Rationale: This sentence directly links plant glucose production to the energy source for almost
all organisms.
Q3 According to the passage, what is the primary pigment responsible for capturing light
energy?
Answer: Chlorophyll
Rationale: The text explicitly identifies chlorophyll as the green pigment in chloroplasts that
absorbs light to initiate photosynthesis.
, Q4 The word ―capture‖ in the first paragraph most nearly means:
Answer: absorb
Rationale: In scientific context, plants ―capture‖ light energy by absorbing specific wavelengths
through chlorophyll.
Q5 Which statement can be reasonably inferred from the passage?
Answer: Photosynthesis requires both light and dark reactions to produce glucose.
Rationale: The passage describes light-dependent reactions (producing ATP/NADPH) and light-
independent reactions (Calvin cycle using those to make glucose).
Q6 What is the main idea of the third paragraph?
Answer: The Calvin cycle uses energy from the light reactions to produce glucose.
Rationale: Paragraph three explains the light-independent stage (Calvin cycle) and how it fixes
carbon into sugar using products from the light reactions.
Q7 The passage implies that photosynthesis primarily occurs in which part of the plant cell?
Answer: Chloroplasts
Rationale: Chloroplasts are repeatedly identified as the organelles containing chlorophyll where
photosynthesis takes place.
Q8 Which of the following is NOT mentioned as a requirement for photosynthesis?
Answer: Nitrogen
Rationale: The passage lists sunlight, carbon dioxide, and water — nitrogen is not mentioned as
necessary for the photosynthetic process itself.
Q9 The tone of the passage can best be described as:
