There are over 1,500 types of algae inlcluding Red Algae, Green Algae, and Blue-Green Algae. One group of algae, the green algae, is even classified with the plants because of how similar the organisms are. 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. Spirulina is considered a superfood by many. The wide variety algae makes them hard to classify. Multicellular organisms are organisms that consist of more than one cell, in contrast to unicellular organisms. 1 decade ago . Micrasterias sp.). Chlamydomonas cells. Algae are also diverse, and may either be unicellular or multicellular. Algae are autotrophic protists that can be found in pond water. Green algae have many forms: unicellular, multicellular, or colonial. Take note that this is found in freshwater and not saltwater. Algae can be unicellular, live in colonies, or even be multicellular. read more. The organisms are living things that are formed by one or more cells. Photosynthetic Algae These are Netrium desmid, an order of unicellular green algae that grow in long, filamentous colonies. There are various examples of unicellular plants, and some of them include bacteria, some types of algae such as diatoms and amoeba. Unicellular organisms fall into two general categories: prokaryotic organisms and eukaryotic organisms. Correct answer to the question Blue green algae multicellular or unicellular - e-eduanswers.com Blue green algae include unicellular organisms as well as multicellular organisms. Green and brown algae are uni cellular. Spirogyra is a unicellular green algae that grows in long, filamentous colonies, making it appear to be a multicellular organism. Algae are one celled organisms that contain chlorophyll, and live on or near the surface. It may be unicellular as in simple algae and fungi or multicellular as in plants: 12. Algae are both unicellular and multicellular. Moreover, their bodies can be spherical, filamentous or sheet-like colonies. Most of them are autotrophic which means that they can harvest carbon dioxide from the atmosphere and convert it to organic matter. Source: University of Wisconsin Still have questions? They lack the sterile covering of cells around their reproductive cells. The cell wall of a green algal cell is comprised chiefly of cellulose. 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. Most often there is a unicellular alga chlamydomonas. From ancient times until early this century, the plant kingdom was thought to include plants, most algae, fungi, and prokaryotes. They can also live symbiotically with fungi, plants and animals, such as in the case of lichen ( algae and fungi). Though green algae display a diversity of life cycles, many have a haplontic life cycle. [1] All species of animals , land plants and most fungi are multicellular, as are many algae , whereas a few organisms are partially uni- and partially multicellular, like slime molds and social amoebae such as the genus Dictyostelium . 1 decade ago. Multicellular definition, composed of several or many cells. The gametes of static multicellular types are free-swimming and also have flagellae. Unicellular green algae are solitary, single-celled photosynthetic organisms (e.g. Get your answers by asking now. They inherited their photosynthetic apparatus from cyanobacteria. Background: The unicellular green alga Chlamydomonas reinhardtii is an important eukaryotic model organism for the study of photosynthesis and plant growth: 13. unicellular gland - a goblet cell mucus - secreting H & E stain : 14. The motile types often use whip like flagellae to propel themselves. It moves in water with the help of two flagella located on the front, narrower end of the cell. Muhammad Shoaib May 7, 2020. The cell is non-motile which is enclosed by cellulosic cell wall. Types of Algae. The algae group is consists of both unicellular and multicellular organisms. Cells are the minimum units of life that have different degrees of complexity depending on their structure or organization. A model organism for the green algae is Spirogyra. Algae span both terrestrial and marine environments, growing almost anywhere there is water and sunlight. As far as I know, any of the algae is unicellular, isn't that the difeiniton of algae?

Because Algae are represented across four kingdoms, namely Bacteria (unicellular prokaryotes), Plantae (multicellular eukaryotes), Chromista (multicellular eukaryotes), and Protozoa (single-celled eukaryotes). Most of these microorganisms are green in color, while a few may be yellowish-brown. Because Chlamydomonas is unicellular, and therefore has no organs, this green algae develops entirely into a gamete. Others are very beneficial to humans health. See more.

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. 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. Source: en.wikipedia.org.
