Rearrange the following sentences to form a coherent paragraph:
1. This process, known as photosynthesis, is fundamental to life on Earth as it forms the base of most food webs.
2. Plants, algae, and some bacteria possess a unique ability to convert light energy into chemical energy.
3. The captured light energy is then used to synthesize glucose molecules from water and carbon dioxide.
4. It begins with the absorption of photons by chlorophyll pigments within the plant cells.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 2, 1, 4, 3.
Logical flow:
-
Sentence 2 introduces the subject: “Plants, algae, and some bacteria possess a unique ability…”
-
Sentence 1 explains the significance of this process: “This process, known as photosynthesis, is fundamental to life on Earth…”
-
Sentence 4 details the first step of the process: “It begins with the absorption of photons by chlorophyll pigments…”
-
Sentence 3 explains the outcome of this process: “The captured light energy is then used to synthesize glucose molecules…”
Final Paragraph:
Plants, algae, and some bacteria possess a unique ability to convert light energy into chemical energy. This process, known as photosynthesis, is fundamental to life on Earth as it forms the base of most food webs. It begins with the absorption of photons by chlorophyll pigments within the plant cells. The captured light energy is then used to synthesize glucose molecules from water and carbon dioxide.
Hence, the chosen option will be correct.
