Explanation:

The complete question is: <em>A scientist has discovered a new plant species in the Amazon rainforest. She tells her fellow scientists that the plant she has found produces a cone. What might they say about how this plant is different from an angiosperm? Its seeds have one or two cotyledons. Its stems' vascular bundles are scattered. It does not depend on insect pollination. It is a seeded vascular plant. </em>

<em>The correct option would be that the plant is a seeded vascular plant and does not depend on insect pollination.</em>

Gymnosperms are the only group of plants that produce cones. They are one of the plant groups that have vascular tissues in the form of xylem and phloem as well as been able to produce seed in the form fo cones. Hence, they are said to be seeded vascular plants.

Gymnosperms also carry out their pollination by relying solely on wind for the transfer of their pollen grain to the female organ. In other words, they do not depend on insect for pollination.
