The order of evolution trend in plants is

The order of evolution trend in plants is Thallophyta, Bryophyta, Pteridophyta, and Spermatophyta. Thallophyta is a group of plants that lack true roots, stems, and leaves, and they include organisms such as algae and fungi. Bryophyta are non-vascular plants that have true roots, stems, and leaves, but they lack a specialized transport system for water and nutrients. Pteridophyta are vascular plants that have specialized tissues for the transport of water and nutrients, and they include ferns and horsetails. Spermatophyta are seed-bearing plants that have evolved further to produce seeds as a means of reproduction. They include gymnosperms and angiosperms. Therefore, the correct order of evolution trend in plants is Thallophyta, Bryophyta, Pteridophyta, and Spermatophyta.
