Viridiplantae (literally "green plants") [6] constitute a clade of eukaryotic organisms that comprises approximately 450,000–500,000 species that play important roles in both terrestrial and aquatic ecosystems. [7] They include the green algae, which are primarily aquatic, and the land plants ( embryophytes ), which emerged from within them.
the paraphyletic group taxon includes the most recent common ancestor, but not all of its descendants. A polyphyletic group does not include the common ancestor of all members of the taxon. And a monphyletic is a group of organisms including the most recent common ancestor and all of its descendants.
Tracheophytes are vascular plants with lignified and non-lignified tissues that include angiosperms, clubmosses, ferns, horsetails, and gymnosperms. Compared to non-vascular plants, these plants have vascular tissues that allow them to grow to large sizes. Nutrients and water in the form of organic solutes are distributed throughout the plant ...
Feb 16, 2024 · Angiosperm, any of about 300,000 species of flowering plants, the largest and most diverse group in the plant kingdom. Angiosperms are vascular seed plants in which the ovule is fertilized and develops into a seed in an enclosed ovary. Learn about angiosperm characteristics, evolution, and importance.
May 9, 2016 · A paraphyletic assemblage of planktonic unicellular, mainly marine green algae forms the early-diverging clades of Chlorophyta, collectively called the prasinophytes.
Gymnosperms, meaning “naked seeds,” are a diverse group of seed plants. According to the "anthophyte" hypothesis, the angiosperms are a sister group of one group of gymnosperms (the Gnetales), which makes the gymnosperms a paraphyletic group. Paraphyletic groups are those in which not all descendants of a single common ancestor are included ...
Clades within clades. A clade (also known as a monophyletic group) is a group of organisms that includes a single ancestor and all of its descendents. Clades represent unbroken lines of evolutionary descent. It’s easy to identify a clade using a phylogenetic tree. Just imagine clipping any single branch off the tree.
