ALGAE
There are 3 different types of algae. Brown Algae, Green Algae and Red Algae.
There are 3 different types of algae. Brown Algae, Green Algae and Red Algae.
Red Algae
The Red Algae is classified in the Kingdom Protista and the Phylum Rhodophyta. It is most common in warmer tropical waters and, if in temperate zones, in deeper water. An example is the "Turkish Wash Cloth".

Brown Algae
The Brown Algae is classified in the Kingdom Protista and the Phylum Heterokontophyta. It is mostly found in marine and temperate zones. An example is "Kelp".

Green Algae
The Green Algae is classified in the Kingdom Protista and the Phylum Chlorophyta. It is a very diverse group that can live in all environments (fresh and salt water, soil). Green Algae can be found in 3 forms: Unicellular, Colonial and Multicellular.
1. Unicellular
Unicellular Green Algae are very common in fresh water as part of phytoplankton. An example is "Chlamydomonas"

1. Unicellular
Unicellular Green Algae are very common in fresh water as part of phytoplankton. An example is "Chlamydomonas"
2. Colonial
Colonial Green Algae lives in long filaments or as colonial spheres. An example is "Volvox".

3. Multicellular
Multicellular Green Algae is mostly marine. They are the ancestors of land plants. An example is "sea lettuce".

WHY DO WE THINK LAND PLANTS DEVELOPED FROM ALGAE
Life evolved in the seas first for more than 3 billion years ago. The first photosynthetic organisms were aquatic green algae. That gave them the advantage to evolve into land plants.
