Onions photosynthesize in their bulbs, which are modified leaf structures.
While it might seem surprising, onions, like other plants, perform photosynthesis. The process primarily occurs in the bulbs of the onion. Let's break down how this works:
Onion Photosynthesis Explained
Here's a look at how onions manage to photosynthesize:
-
Modified Leaf Structure: The bulb of an onion isn't a root; it's a modified leaf structure. This is crucial because leaves are the primary sites of photosynthesis in most plants.
-
Photosynthesis in the Bulb: According to the provided reference, photosynthesis does occur in the onion bulb.
-
Minimal Glucose Production: The bulbs create a small amount of glucose during photosynthesis.
-
Starch Conversion and Storage: This glucose is then converted into starch and stored in the bulb. This is why onions are a source of carbohydrates.
