Question

a botanist has discovered a new plant species and is trying to classify the plant. its seed has one cotyledon, it has six flower parts, its leaves have parallel veins, its stem is herbaceous, and the vascular bundles in its stem are scattered throughout the stem. which best classifies this plant?

• gymnosperm and dicot
• gymnosperm and monocot
• angiosperm and monocot
• angiosperm and dicot

Explanation:

• Angiosperms: Angiosperms are flowering plants that produce seeds enclosed within a fruit. Monocots and dicots are both types of angiosperms. Gymnosperms have naked seeds (not enclosed in a fruit). Since the plant has seeds (a key feature of angiosperms or gymnosperms), but we need to further distinguish.
• Monocot characteristics:
• One cotyledon: Monocots have one cotyledon (seed - leaf) in their seeds, while dicots have two.
• Flower parts in multiples of three: The plant has six (which is a multiple of three) flower parts.
• Parallel veins in leaves: Monocots typically have parallel - veined leaves, while dicots have netted (reticulate) veins.
• Scattered vascular bundles in herbaceous stems: In monocots with herbaceous stems, vascular bundles are scattered. In dicots, vascular bundles are arranged in a ring.

Answer:

angiosperm and monocot
