Prokaryotic. . After knowing What Is Blue Green Algae and the types, here are The characteristics of the Blue Green Algae. By continuing you agree to the Copyright © 2020 Elsevier B.V. or its licensors or contributors. However, some protists contain plastids that are believed to be from other eukaryotes. Prokaryotic (the cell nucleus is not covered with a membrane) Shape. The characteristics of the Blue Green Algae. They use chlorophyll … This form of algae can be unicellular (single-cell), colony (combined cells) or filament (yarn), Example: Most are found in combination with chlorophyll b, c or d. Algae have adapted to use the other forms of chlorophyll due to deep water and use the varying wavelengths of sunlight.Plants also have a complex, multi-cellular reproductive system that can require the assistance of wind, birds, or bugs for pollination. The position of green algae is more ambiguous. Several studies indicate that a prasinophyte The conjugating green algae (Zygnematophyceae) are among the most widespread and commonly encountered green algae in freshwaters of North America. Details are provided about methods used to collect and preserve filamentous green algae and stoneworts, along with a list of works dealing with North American genera that is useful for species identification.Green algae and plants are believed to be descendents of the original plastid-harboring eukaryote. Chlorophyceae (Green algae) General characterstics of Chlorophyceae. Rather, they are a type of bacteria known as cyanobacteria. North American representatives of this group belong to 79 genera of the classes Chlorophyceae, Charophyceae, Coleochaetophyceae, Klebsormidiophyceae, Ulvophyceae and Trebouxiophyceae. Common in the benthos and plankton in ponds, streams, and ephemeral streams and The conjugating green algae have a relatively high diversity compared with other groups of green algae that occur in North America.

Green Alga. They also do not need stem like structures like plants because they are supported by water. These protists have within their endoplasmic reticulum an endosymbiont resembling a eukaryote. Their ubiquity makes rather difficult to summarize their ecology in a few words since these organisms are archetypical of the incredibly vast possibility of adaptation shown by Life on our planet. From a taxonomic point of view, they constitute a paraphyletic group as they likely have a common ancestor with plants: they have the same type of pigments and produce the same kind of carbohydrates during photosynthesis as do land plants. Most of the harmful algae blooms (HABs) occur in freshwater. Green Algae Algae Characteristics: Algae are photosynthetic organisms that must live in or near a water source. We present here an account of these genera with descriptions of their morphology, reproduction, and ecology, together with line drawings, color photographs, and a dichotomous key for generic-level identification. Algae also does not need protection from drying out for they are aquatic. Green algae are divided into charophytes, green algae that are closely related to land plants, and chlorophytes, green algae comprised of over 7,000 species of aquatic organisms. This endosymbiont possesses its own plasma membrane and ribosomes (which are both similar to those of eukaryotes) as well as the remnant of a nucleus containing its own DNA (a nucleomorph), and finally plastids. Algae, comparatively, can reproduce through tiny spores or even by replication or the growth of broken pieces. The most diverse genera are We use cookies to help provide and enhance our service and tailor content and ads. All algae contain chlorophyll a.
