Simplified diagram of a chlorophyte cell combining structures seen across the phylum: 1) flagellum; 2) synistosome with fibers adhering to a pair of basal bodies; 3) basal body; 4) microtubular rootlet belonging to the "X-2-X-2" arrangement, in this case 4-2-4-2 (only front-facing rootlets are shown); 5) flagellar pit (only two of four flagella ...
A floral diagram is a graphic representation of the structure of a flower. It shows the number of floral organs, their arrangement and fusion. Different parts of the flower are represented by their respective symbols. Floral diagrams are useful for flower identification or can help in understanding angiosperm evolution.
Anatomy of a flower. A flower's anatomy, as defined by the presence of a series of organs (sepals, petals, stamens and carpels) positioned according to a given pattern, facilitate sexual reproduction in flowering plants.

Both the "chlorophyte algae" and the "streptophyte algae" are treated as paraphyletic (vertical bars beside phylogenetic tree diagram) in this analysis. [ 22 ] [ 23 ] The classification of Bryophyta is supported both by Puttick et al. 2018, [ 24 ] and by phylogenies involving the hornwort genomes that have also since been sequenced.
