Which of the following plants has a taproot example?

The correct answer is carrot, as it is a prime example of a plant that develops a taproot system. A taproot is characterized by a single, thick primary root that grows deep into the soil, allowing the plant to access moisture and nutrients from deeper layers. In addition to anchoring the plant, taproots store nutrients and carbohydrates, which is why carrots, in particular, have a fleshy taproot that is edible and rich in sugars.

In contrast, bananas have a fibrous root system which consists of many thin roots that spread out horizontally in the soil. Wheat also has a fibrous root system, providing extensive coverage for nutrient uptake but lacking the single, dominant root structure. Similarly, onions develop a bulb that stores nutrients, and while they have a root system, it does not form a taproot. This distinction makes the carrot a textbook example of a taproot plant.
