<!--Note that the higher-level [[Statistical classification|classification]] of plants varies considerably. Some authors have restricted the [[Kingdom (biology)|kingdom]] [[Plantae]] to include only embryophytes, others have given them various names and ranks. The groups listed here are often considered divisions or [[phylum|phyla]], but have also been treated as classes, and they are occasionally compressed into as few as two divisions. Some classifications, indeed, consider the term Embryophyta at the superphylum (superdivision) level, and include Land Plants and some Charophyceae in a subkingdom named [[Streptophyta]].
On a microscopic level, embryophyte cells remain very similar to those of green algae. They are [[eukaryote|eukaryotic]], with a [[cell wall]] composed of [[cellulose]] and [[plastid]]s surrounded by two membranes. These usually take the form of [[chloroplast]]s, which conduct photosynthesis and store food in the form of [[starch]], and characteristically are pigmented with chlorophylls ''a'' and ''b'', generally giving them a bright green color. Embryophytes also generally have an enlarged central [[vacuole]] or tonoplast, which maintains cell [[turgor]] and keeps the plant rigid. They lack [[flagellum|flagella]] and [[centriole]]s except in certain [[gamete]]s.-->
