WebThe diversity of plants existing today is the result of 450-700 million years of evolution and adaptation to the terrestrial environment. The common ancestor of all plants is thought to be very similar to species in the group of green algae known as the charophytes. Charophytes are similar to modern plants.

WebIn vascular plants, the principal generation or phase is the sporophyte, which produces spores and is diploid (having two sets of chromosomes per cell). (By contrast, the principal generation phase in non-vascular plants is the gametophyte, which produces gametes and is haploid - with one set of chromosomes per cell.)

WebPlant evolution is an aspect of the study of biological evolution, predominantly involving evolution of plants suited to live on land, greening of various land masses by the filling of their niches with land plants, and diversification of groups of land plants.

WebVascular plants [ edit] Australia has over 30,000 described species of vascular plants, these include the angiosperms, seed-bearing non-angiosperms (like the conifers and cycads), and the spore-bearing ferns and fern allies. [17] Of these about 11% are naturalised species; the remainder are native or endemic. [18]

WebMay 06, 2014 · Nonvascular plants are generally small and do not extend much more than a few inches above the surface they are growing on (Fig. 2). Their appearance can best be described as a "carpet of green." The plant body that is most obvious is the gametophyte generation, which is haploid.Nonvascular plants typically grow in moist environments.

WebThe ability of vascular plants to flourish in so many different habitats is a key factor in their having become the dominant group of terrestrial plants. The vascular plants are divisible into the nonseed plants ( lower vascular plants, or cryptogams) and those that reproduce by seeds (higher vascular plants, or phanerogams).
