Answer: Siphonogamy
Both angiosperms and gymnosperms are seed-bearing plants with a few similarities. In plants, siphonogamy is a process in which the male gametes are transferred via the pollen tube to the female gametes. In both angiosperms and gymnosperms, this phenomenon occurs.
Angiosperm
The term angiosperm is derived from greek Word for container. As the name implies, angiosperms are vascular plants that bear fruit or mature ovaries with seeds. Flowers that bear reproductive organs and fruits are produced by angiosperm. These plants are more adaptive to the terrestrial habitat and have a very wide distribution.
Gymnosperms
Gymnosperms are other groups of plants that carry seeds without coating directly on sporophylls. Gymnosperms are vascular plants of the Kingdom Plantae that bear naked seeds, as the title suggests. Cypress, Gnetum, oak, spruce, redwood, ginkgo, cycads, juniper, fir, and Welwitschia are only a few instances of these plants. There’s very few gymnosperm varieties.
