Cell Structure And Organelles

Step 1: Understanding the role of sphaerosome.
Sphaerosomes are cell organelles involved in the synthesis and storage of fats, particularly in plants. These structures are also known as lipid bodies. They store lipids and are essential for energy storage.
Step 2: Analyzing the options.
(A) Glyoxysome: Incorrect. Glyoxysomes are specialized peroxisomes found in plants, involved in converting fatty acids to carbohydrates, not storing fat.
(B) Peroxisome: Incorrect. Peroxisomes are involved in various metabolic reactions, including detoxifying harmful substances, but not fat synthesis and storage.
(C) Sphaerosome: Correct. Sphaerosomes are the organelles responsible for fat synthesis and storage in plant cells.
(D) Ribosome: Incorrect. Ribosomes are involved in protein synthesis, not fat storage or synthesis.
Step 3: Conclusion.
The correct answer is (C) Sphaerosome, as it is the organelle responsible for the synthesis and storage of fats in plants.
