Contributions of Anton va n Leeuwenhoek, ) is a plant-like organism that uses sunlight to produce energy in a process called . photosynthesis. . Algae are extremely important organisms because they are considered to be the primary oxygen-producing organisms on Earth. In addition to above mentioned some algae also occur in uncommon habitat and termed as:. Halophytic algae. . They grow in the highly concentrated salt lakes.. Symbiotic algae. . They grow in association with fungi, bryophytes, gymnosperms or angiosperms. . chlorophyllus. . thallophytes. that can manufacture their own food and they produce oxygen during photosynthesis. So they are called as autotrophic . thallophytes. .. The term . thallus. is used for plant body that is not differentiated into root, stem and leaves. Lacks vascular system..
