Meaning and Definition
A member of a group of green algae, particularly those in the class Charophyceae, which are considered the closest living relatives to land plants.
In paleobotany and evolutionary biology, charophyte refers to fossil or extant algae whose structural and reproductive features provide critical evidence for the transition of plant life from aquatic to terrestrial environments.

FAQ
Frequently Asked Questions
No, charophytes are a group of green algae. However, they are part of the broader clade Streptophyta, which includes both charophytes and all land plants (embryophytes), making them the closest algal relatives to plants.
Most charophytes are found in freshwater or brackish habitats, such as lakes, ponds, and slow-moving streams, often attached to substrates like rocks or sediment.
They are critically important in evolutionary studies as models for understanding the adaptations (e.g., in cell wall structure, reproduction, and phytohormone pathways) that allowed photosynthetic life to colonize land.
Stoneworts, such as those in the genus Chara or Nitella, are familiar examples. They are often coarse to the touch due to calcium carbonate deposits.
