An example of single membrane cell organelle associated with oil bodies in plant cells is:
An example of single membrane cell organelle associated with oil bodies in plant cells is:
Show Hint
Associate the prefix "Glyoxy-" in glyoxysome with the glyoxylate cycle, which is responsible for converting fats (oil bodies) into carbohydrates in germinating seeds.
This functional link makes their physical association necessary.

The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Oil bodies (lipid droplets or oleosomes) are organelles that store triacylglycerols in plant cells, especially during seed development.
During seed germination, these stored lipids must be converted into carbohydrates to support the growing seedling.
Step 2: Detailed Explanation:
Glyoxysomes are specialized peroxisomes found in plants, particularly in fat-storing tissues of germinating seeds.
They are bounded by a single membrane.
These organelles contain the enzymes of the glyoxylate cycle, which bypasses steps of the citric acid cycle to convert acetyl-CoA (derived from $\beta$-oxidation of fatty acids) into succinate.
Because they process the fatty acids stored in lipid bodies, glyoxysomes are physically positioned immediately adjacent to oil bodies.
This spatial association minimizes the diffusion distance for fatty acids as they are mobilized and oxidized.
Step 3: Final Answer:
The glyoxysome is the single-membrane organelle associated with oil bodies in plant cells.

- Which of the following molecules can be classified under glycosphingolipid category?
- The bicarbonate buffer is a principal buffering system in blood plasma. The ratio of the bicarbonate to carbonic acid required to maintain pH of plasma at 7.4 is:
- Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): The disruption of $\beta$-oxidation of fatty acids in plants can potentially reduce stress-induced ROS accumulation and improve its stress tolerance.
Reason (R): In plants, $\beta$-oxidation of fatty acids takes place predominantly in peroxisomes, where first enzyme of $\beta$-oxidation viz. fatty acyl CoA oxidase produces large amounts of hydrogen peroxide.
In light of the above statements, choose the correct answer from the options given below. - The serum level of which of the following metabolites can effectively distinguish "Vitamin B12 deficiency" from "Folate deficiency" ?
