How is cyanobacteria different from green algae

Therefore, green algae are photoautotrophs and the food is stored as starch and fats. Since algae are eukaryotic organisms, they contain membrane-bound organelles in their cells. The genetic material of green algae occurs in the nucleus. Moreover, the photosynthetic pigments are arranged into chloroplasts. A single cell may contain one or more chloroplasts. Green algae can be unicellular, multicellular or living in colonies.

Some green algae show a coenocytic growth in which several green algae are composed of a one, large cell, without cross walls. The large cell can be either uninucleated or multinucleated. Some green algae live in symbiotic relationships with fungi, forming lichens. Figure 1: Stigeoclonium. The asexual reproduction of green algae occurs by fission , budding , fragmentation or by the formation of zoospores.

The sexual reproduction occurs by the formation of isogamous both gametes are motile and same size or anisogamous female non-motile and male motile gametes. Most green algae show alteration of generations with a haploid phase and diploid phase in the life cycle. The green algae are classified into two phyla; Chlorophyta and Charophyta.

Most Chlorophyta occurs in the marine water, freshwater or subaerial. The Chlorophyta includes Trebouxiophyceae, Chlorophyceae, Bryopsidophyceae seaweeds , Ulvophyceae seaweeds , Dasycladophyceae, and Siphoncladophyceae.

The Charophyta entirely live in freshwater habitats. The term cyanobacteria refers to any photosynthetic bacteria. Some cyanobacteria can live as heterotrophs. Cyanobacteria can be found in the soil, and in both freshwater and marine water habitats. This is a really big mistake, and green alage can range from a multicellular organism to a unicellular organism examples are Chlamydomonas and Volvox. Brown algae are the only kind of algae species that can be only multicellular.

The article describes cyanobacteria as not using light waves, but using h2o as source of electron…. I question that, or am missing something. Name required. Email required.

You agree that we have no liability for any damages. Structure and habitat Algae are small unicellular organisms whereas cyanobacteria are multi-cellular organisms and larger in size. Reproduction Green algae can reproduce sexually, as well as asexually.

Uses Green algae have a nutrient value similar to most of the green plants. Summary Both green algae and cyanobacteria have evolved from algae. Author Recent Posts. Latest posts by rachita see all.

The work of Sandrini et al. Certainly such niche exploitation by different strains of cyanobacteria is used, for instance, in Cylindrospermopsis raciborskii Burford et al.

Thus the competition outcomes in the real world are likely to be much more complicated than the relatively simple systems Ji et al. Nonetheless, this work is a significant and useful advance in understanding and modelling possible consequences of competition between phytoplankton in a changing environment, and can be complemented by experimental evolution studies to take into account genetic adaptation Raven and Beardall, ; Sandrini et al.

Global Change Biology 17 , — Inorganic carbon acquisition by chrysophytes. It has a gliding movement. It also contains phycocyanin, phycoerythrin, and chlorophyll which are termed photosynthetic pigments. These pigments have different colors. Phycoerythrin is red, and Phycocyanin is blue.

It has vacuoles inside them. It is a prokaryotic organism. Some Cyanobacteria are heterotrophs. Cyanobacteria are not capable of swimming in water. They can change their depth in water. It does not undergo any sexual reproduction. It has no memory-bound organelles. It is capable of producing its food. It has a high capability to store nutrients in them. It lives symbiotically. It can be found in terrestrial habitats. It stores its food as starch. The gliding behavior in them occurs due to changes in the trichome which changes the depth of the organism inside water.

It undergoes asexual reproduction. Cell division and formation of the plate in the organism lead to asexual reproduction. This is a photosynthetic organism. It has chlorophyll present in it, which makes it green in color.
