Which group of plants is also characterized by having two seed leaves?

The group of plants characterized by having two seed leaves is recognized as dicots. This classification stems from their embryonic development, where two cotyledons (the seed leaves) emerge during growth. Cotyledons serve various roles, including providing nutrients to the developing plant until it can photosynthesize on its own.

In contrast, monocots, another major category of flowering plants, typically have one cotyledon. This fundamental difference in seed structure helps botanists and horticulturists classify and identify plant species.

Annuals and biennials refer to the life cycles of plants rather than their seed structure; annuals complete their life cycle within one growing season, while biennials take two seasons to mature. Therefore, the relevant characteristic of having two seed leaves distinctly places dicots as the correct answer in this context.
