Question

Gnetum resembles angiosperms in mamy respect yet it is not placed under angiosperms, why?​

Answer 1

Explanation:

Such vessels form when cells join end to end in the xylem tissue and are common in flowering plants. Most gnetophytes produce naked (exposed) seeds, like the other gymnosperms—ginkgo, cycads, and conifers. Gnetum leyboldii, unlike most gymnosperms, produces seed enclosed in a juicy, fruit-mimicking layer.
