Which of the following plant is a dicot ?

Question

Accepted Answer

Option 4, Congress Grass (Parthenium), is the correct answer because it is a dicot plant. Dicots, or dicotyledons, are a group of flowering plants whose seeds typically have two embryonic leaves or cotyledons. Parthenium, commonly known as Congress Grass, exhibits characteristics typical of dicots, such as having broad leaves with a network of veins, a taproot system, and floral parts that are usually in multiples of four or five.

Here's why the other options are incorrect:

1. **Bamboo**: Bamboo is a monocot. Monocots, or monocotyledons, are characterized by having seeds with a single cotyledon. Bamboo plants have parallel leaf venation, fibrous root systems, and floral parts typically in multiples of three, all of which are characteristics of monocots.

2. **Banana**: Banana plants are also monocots. They have a single cotyledon in their seeds, parallel leaf venation, and a fibrous root system. These features align with the typical characteristics of monocots.

3. **Wheat**: Wheat is another example of a monocot plant. It has a single cotyledon, parallel venation in its leaves, and a fibrous root system. The floral parts of wheat are also arranged in multiples of three, which is consistent with monocot characteristics.

In summary, Congress Grass (Parthenium) is the only option among the given choices that is a dicot, as it possesses the defining features of dicotyledonous plants.
