Life as we know it would not exist without plants to convert sunlight and inorganic compounds into food energy. In Kingdom Plantae, plant species are classified according to their method of reproduction. One group is the "seed plants," which can be divided into two subgroups called angiosperms and gymnosperms.

The gymnosperms , also known as Acrogymnospermae , are a group of seed-producing plants that includes conifers , cycads , Ginkgo , and gnetophytes.

Angiosperms vs. Gymnosperms

Many wood physical and mechanical traits are important functional attributes for tree species, but variation in these traits among taxonomic categories such as between gymnosperms and angiosperms is still poorly documented.

Here, the systematic differences in 12 traits and their allometric relationships between the two tree categories and the potential effects of phylogeny are explored based on a database for major gymnosperm and angiosperm tree species across China. The results are summarized below: 1 means of wood traits were all significantly lower in gymnosperms than in angiosperms.

The allometric slopes of other traits, except for hardness of transverse section HES , against ADD for gymnosperms were significantly steeper than or similar to the corresponding slopes for angiosperms. On the contrary, the slopes of other traits except TSC against RSC for gymnosperms were shallower than or similar to their counterparts for angiosperms. The present analyses demonstrated a systematic difference in wood traits between two major plant categories, which suggests the evolutionary divergence TSC, RSC and convergence ADD in key functional traits among woody plants.

Angiosperm vs Gymnosperm: What are the Similarities & Differences?

In this paper, we aim to understand how genes and gene families have contributed to the major functional and morphological differences in gymnosperms, and how this information can be used for applied breeding and biotechnology. In addition, we have analyzed the angiosperm versus gymnosperm evolution of the pleiotropic drug resistance PDR gene family with a wide range of functionalities in plants' interaction with their environment including defense mechanisms. Some of the genes reviewed here are newly studied members of gene families that hold potential for biotechnological applications related to commercial and pharmacological value. Some members of conifer gene families can also be exploited for their potential in phytoremediation applications. Gymnosperms are an ancient and widespread nonflowering plant lineage of great economic and ecological importance. Recent studies highlighted the underpinnings of the major morphological, genomic, and functional differences that shaped the evolutionary divergence among gymnosperms and flowering plants.


Angiosperms and Gymnosperms are divided in the soil of the type of seed they bear. Angiosperm are those whose seeds are covered in fruit. Gymnosperms.

Evolution of Gymnosperms and Angiosperms

Белокурая девушка смотрела на него недоверчиво. - Вы это сделаете? - выдавила она, и глаза ее засветились надеждой.  - Вы купите мне билет домой. О Боже, я вам так благодарна. Беккер растерялся. Очевидно, он ошибался. Девушка обвила его руками.

Президент объяснил, что преподавательских часов будет меньше, бумажной работы больше, - но гораздо выше будет и жалованье. Сьюзан хотелось закричать: Дэвид, не соглашайся. Это не принесет тебе радости. У нас много денег - какая разница, кто из нас их получает. Но это была чужая епархия. В конце концов ей пришлось смириться.

В глазах Клушара вспыхнуло возмущение. - У немца. Его взял немец.
