FFA Horticulture CDE General Practice Exam

Which of the following is a characteristic of dicots?

1. Typically have one cotyledon

2. Typically have flower parts in multiples of three

3. Leaves usually have a network of veins

4. Root system is usually fibrous

The correct answer is: Leaves usually have a network of veins

Dicots, or dicotyledons, are known for having specific structural features that distinguish them from monocots. The presence of a network of veins in the leaves is one of the defining characteristics of dicots. This reticulate or branched vein pattern is generally more complex than the parallel vein structure typically found in monocots. The network allows for more efficient transportation of water and nutrients throughout the leaf, supporting its various functions. In contrast, other characteristics such as having one cotyledon, flower parts in multiples of three, and a fibrous root system are associated with monocots. By understanding these structural distinctions, one gains insight into how plant classification and characteristics impact biological and ecological functions.
