Green algae contain endosymbiotic cyanobacteria derived primary chloroplasts. Green algae have many forms: unicellular, multicellular, or colonial. Unicellular definition, having or consisting of a single cell. Cells are the minimum units of life that have different degrees of complexity depending on their structure or organization. Multicellular forms are those that appear filamentous or forming leaf-like thallus (Ulva sp. A unicellular organism, also known as a single-celled organism, is an organism that consists of a single cell, unlike a multicellular organism that consists of multiple cells.

Though green algae display a diversity of life cycles, many have a haplontic life cycle. The gametes of static multicellular types are free-swimming and also have flagellae. Some unicellular species of green algae, many golden algae, euglenids, dinoflagellates, and other algae have become heterotrophs (also called colorless or apochlorotic algae), sometimes parasitic, relying entirely on external energy sources and have limited or no photosynthetic apparatus. Algae are both unicellular and multicellular. Photosynthetic Algae These are Netrium desmid, an order of unicellular green algae that grow in long, filamentous colonies.

For those who are not familiar with this, this is a type of green algae that you will find in various tropical areas of the world. It moves in water with the help of two flagella located on the front, narrower end of the cell. Both blue green algae and green algae include unicellular and multicellular organisms. As far as I know, any of the algae is unicellular, isn't that the difeiniton of algae? The motile types often use whip like flagellae to propel themselves. Figure 01: Anabaena – Blue Green Algae. Most of them are autotrophic which means that they can harvest carbon dioxide from the atmosphere and convert it to organic matter. Characteristics of Unicellular organisms - example Unicellular organisms are also called single-celled organisms and have the the following characteristics. Most algae are multicellular but there are few algae that are unicellular. One group of algae, the green algae, is even classified with the plants because of how similar the organisms are. Algae are autotrophic protists that can be found in pond water. They inherited their photosynthetic apparatus from cyanobacteria. These organisms are found in the supergroups Chromalveolata (dinoflagellates, diatoms, golden algae, and brown algae) and Archaeplastida (red algae and green algae). Multicellular organisms are organisms that consist of more than one cell, in contrast to unicellular organisms. For example, I. Chlorophyta is unicellular: I. Chlorophyta.
