What is the morphology of Rhodophyta?
red algae, (division Rhodophyta), any of about 6,000 species of predominantly marine algae, often found attached to other shore plants. Their morphological range includes filamentous, branched, feathered, and sheetlike thalli.
What are the characteristics of Rhodophyta?
The Rhodophyta, the red algae, constitute a division of organisms that share the following combination of attributes: eukaryotic cells, lack of flagella, floridean starch, phycobiliprotein pigments (red and blue), un-stacked thylakoids, and chloroplasts lacking an external endoplasmic reticulum (Woelkerling, 1990).
What is the importance of Rhodophyta?
Rhodophyta are primary producers. They provide habitats for other aquatic organisms. In addition, Rhodophyta play an important part in the establishment and maintenance of coral reefs. Those species found in coral reefs are called coralline algae; they secrete a shell of carbonite around themselves.
What is the life cycle of Rhodophyta?
Triphasic Life Cycle Most of the red algae have three distinct phases in their life cycle- the gametophyte, carposporophyte and the tetrasporophyte. 1. Gametophyte is a free-living haploid plant which is concerned with sexual reproduction. It produces the gametes.
Is Rhodophyta photosynthetic?
Rhodophyta rōdŏf´ətə [key], phylum (division) of the kingdom Protista consisting of the photosynthetic organisms commonly known as red algae. Most of the world’s seaweeds belong to this group.
What is the kingdom of Rhodophyta?
Plant
Archaeplastida
Red algae/Kingdom
Where are Rhodophyta found?
Rhodophyta are cosmopolitan, found from the artic to the tropics. Although they grow in both marine and fresh water, 98% of the 6,500 species of red algae are marine. Most of these species occur in the tropics and sub-tropics, though the greatest number of species is temperate.
Why are Rhodophyta called red algae?
The red “algae” Red algae are red because of the presence of the pigment phycoerythrin; this pigment reflects red light and absorbs blue light.
How old is Rhodophyta?
Rhodophyta: Fossil Record Multicellular rhodophytes were present in the late Precambrian; the oldest may be as old as 1.25 billion years. Because of their ability to secrete calcium carbonate, calcareous red algae have a better Phanerozoic fossil record than many other groups of algal protists.
