Blue-green algae belong to. Frequently Asked Questions. Green algae have dark- to light-green coloration that comes from having chlorophyll a and b, which they have in the same amounts as "higher plants"—the plants, including seed plants and ferns, that have well-developed vascular tissues that transport organic nutrients. They are autotrophic in … This class of food belongs in a unique niche. Green algae contain the same carotenoids and chlorophyll a and b as land plants, whereas other algae have different accessory pigments and types of chlorophyll molecules in addition to chlorophyll a. The diplobiontic species, such as Ulva, follow a reproductive cycle called alternation of generations in which two multicellular forms, haploid and diploid, alternate, and these may or may not be isomorphic (having the same morphology). As a whole, these types of fossils represent nearly 7/8th of the history of life on this planet! Cyanobacteria are a group of bacteria. They are now considered as more related to bacteria than algae. Moreover, photosynthesis first evolved in bacteria. What does it mean when you see a dead bee? Blue-green algae (cyanophytes or cyanobacteria) sit on the phylogenetic fence between being bacteria and algae, with an ongoing tug of war among taxonomists as to which group they belong. To what kingdom(s) do algae belong? Phylum: Rhodophyta. What are some examples of industrial goods? red algae. most common in warmer tropical waters. The group consists of red algae, green algae and land plants. Blue-green algae, also known as Cyanobacteria, are a group of photosynthetic bacteria that many people refer to as "pond scum." Using cladistic analysis (a method for determining evolutionary relationships), the green algae should be grouped with the land plants, the chromophyte algae should be grouped with the aquatic fungi and certain protozoa, and the Euglenophyceae are most closely related to the trypanosome flagellates, including the protozoa that cause sleeping sickness. Remains of colonial blue-green algae have been found in rocks dating back more than 4 billion years. Download PDF's. Copyright 2021 FindAnyAnswer All rights reserved. Option 1 Protista. Maths.
