Which type of seed has two cotyledons and is classified as a dicotyled...
Chickpea is classified as a dicotyledon because it contains two cotyledons, which are the two halves of the seed that store nutrients for the developing plant. In contrast, maize is a monocotyledon, characterized by having only one cotyledon. This distinction plays a significant role in plant classification and affects other traits, such as leaf structure and root systems. For example, dicots generally exhibit reticulate venation in their leaves, while monocots show parallel venation. Understanding these differences is essential for studying plant biology and agriculture.

Understanding Dicotyledons
Dicotyledons, commonly referred to as dicots, are a category of flowering plants that are characterized by having two cotyledons in their seeds. Cotyledons are the first leaves that appear when a seed germinates.
Examples of Seeds
To clarify the answer regarding the seeds mentioned:
- Wheat: This is a monocot, which means it has one cotyledon.
- Rice: Also a monocot, rice seeds have a single cotyledon.
- Chickpea: This is a dicot, featuring two cotyledons.
- Maize: Similar to wheat and rice, maize is a monocot with one cotyledon.
Why Chickpea is the Correct Answer
- Cotyledon Count: Chickpeas have two cotyledons, aligning with the definition of dicotyledons.
- Plant Characteristics: Dicotyledons usually exhibit broad leaves and have a net-like vein pattern.
- Diversity: The dicot family includes many other important plants such as beans, peas, and sunflowers.
Conclusion
Thus, among the options provided, chickpea (option C) is the only seed that meets the criteria of having two cotyledons, classifying it as a dicotyledon. Understanding these classifications helps in the study of botany and plant biology, providing insights into plant development and diversity.
