Chlorophyta
Chlorophyta
Chlorophyta (pronounced: klor-oh-fy-tuh) is a division of green algae, informally called green algae. They are ubiquitous, with species inhabiting various environments ranging from marine and freshwater habitats to terrestrial and even aerial habitats.
Etymology
The term "Chlorophyta" is derived from the Greek words "chloros" meaning green, and "phyton" meaning plant. This is in reference to the green pigmentation of most species in this division, which is due to the presence of chlorophyll.
Classification
Chlorophyta is a division within the kingdom Plantae. It is further divided into four classes: Chlorophyceae, Ulvophyceae, Trebouxiophyceae, and Prasinophyceae. Each class contains different orders, families, genera, and species of green algae.
Characteristics
Members of Chlorophyta are photosynthetic organisms with chlorophyll a and b, which give them their characteristic green color. They store energy in the form of starch, and their cell walls are typically made of cellulose. Most species are aquatic, but some can also be found in terrestrial environments.

- Chlorophyll: A green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis.
- Photosynthesis: The process by which green plants and some other organisms use sunlight to synthesize foods with the aid of chlorophyll.
