Question

Select the CORRECT match of cell organelle and its function.

• A. Leucoplast – site for photosynthesis
• B. Smooth endoplasmic reticulum – extracellular digestion
• C. Sphaerosome – storage and synthesis of proteins
• D. Vacuole – osmoregulation and excretion

Hint:

Large vacuoles in plant cells help maintain turgidity and ionic balance.

Answer 1

The Correct Option is D

Step 1: Understanding cell organelles.
Each cell organelle performs specific functions essential for the survival and regulation of the cell.
Step 2: Evaluating the given matches.
Leucoplasts are involved in storage, not photosynthesis.
Smooth endoplasmic reticulum is involved in lipid synthesis and detoxification, not digestion.
Sphaerosomes are mainly involved in lipid storage, not protein synthesis.
Vacuoles help in maintaining osmotic balance and in excretion of waste materials.
Step 3: Analysis of options.
(A) Incorrect — photosynthesis occurs in chloroplasts.
(B) Incorrect — SER does not perform digestion.
(C) Incorrect — proteins are synthesized by ribosomes.
(D) Correct — vacuole performs osmoregulation and excretion.
Step 4: Conclusion.
The correctly matched pair is Vacuole – osmoregulation and excretion.
