Answer:
Any plant of the department Spermatophyta, comprising all styles of seed-bearing plant life, ANGIOSPERMS and GYMNOSPERMS.
Explanation:
Traits of Spermatophyta
Spermatophyta are seed plant life that encompass Angiospermae (plant life with flowers) and Gymnospermae ( plant life with cones). The plant frame is nicely differentiated as roots, stems, leaves and seed bearing structures. All the plant life are photosynthetic in nature as they include inexperienced pigment referred to as chlorophyll.
A entire genome duplication occasion withinside the ancestor of seed plant life passed off approximately 319 million years ago. This gave upward thrust to a chain of evolutionary adjustments that resulted withinside the starting place of seed plant life.
A center Devonian (385-million-year-old) precursor to seed plant life from Belgium has been diagnosed predating the earliest seed plant life with the aid of using approximately 20 million years. Runcaria, small and radially symmetrical, is an integumented megasporangium surrounded with the aid of using a cupule. The megasporangium bears an unopened distal extension sticking out above the mutlilobed integument. It is suspected that the extension become worried in anemophilous (wind) pollination. Runcaria sheds new mild at the series of individual acquisition main to the seed. Runcaria has all the features of seed plant life besides for a stable seed coat and a device to manual the pollen to the seed.
