Any plant which is Green in colour has Chlorophyll. Chlorophyll is the pigment found in Chloroplasts which makes the Green Colour on Algae as well as helps the Algae to Photosynthesize.
Brown algae are photosynthetic, so it obtains its energy by converting light energy.
The theory of plants evolution that started from multicellular green algae is supported with evidence. First, the color and shape of small plants is similar with the green algae. Also, reproductive cycle , cell walls, the photosynthetic pigments are the same.
Plants enclose and protect the embryo within the female plant while green algae do not.
cell wall composition,photosynthetic pigments and multicellularity
Chlamydomonas is not harmful to us because it is a photosynthetic organism Also a green Algae
Cyanobacteria, also called blue-green algae, are bacteria that photosynthesize but do not have chloroplasts.
sunny water that is rich in nutrients.
Probably the green algae, which descended from cyanobacteria. Seaweeds come in three colours, green, brown and red, and each has different photosynthetic mechanisms - not only chlorophyll. The intertidal zone may have played an important part in the colonization of the land from aquatic plants.
A symbiotic relationship between a fungus and green algae or cyanobacterium is a lichen. This occurs because lichen are composite organisms that consist of a symbiotic association to a fungus with a photosynthetic partner. In this example the photosynthetic partner is the cyanobacteria.
Most Algae are plants and as such will undergo photosynthesis in order to produce ATP which is needed for plant growth. Blue-Green Algae are not truly algae they are Prokaryote Cyanobacteria because their nucleus is not enclosed in the membrane (also undergo photosynthesis). All Algae are Eukaryotic and undergo photosynthesis.
Algae have photosynthetic nutrition.
