The Charales are an order of green algae, and are believed to be the closest relatives of the embryophyteplants. They are branched, multicellular green algae that grow in fresh water. They are often called stoneworts, because the plants can become encrusted in lime (calcium carbonate) after some time. They are unique in having a whorl of small branchlets at each node in the stipe. Its antheridia and oogonia are protected by a layer of sterile cells when mature, and have the most complex structure of all green algae.

Moreover, sequence information from green algal groups that are sister to the land plants, the Charales and Coleochaetales, may help illuminate the evolutionary process that led to the transition of plants onto land.
The Charales are an order of green alga-like plants believed to be the closest relatives of the green land plants.
Its antheridia and oogonia are protected by a layer of sterile cells when mature; the oogonium is oblong in shape and consists of a single egg, while the spherical antheridium is packed with threadlike cells that produce sperm.
As a result, the Charales have the most complex structure of all green algae, if indeed they should be so labelled.
