What are Rhodophyta cell walls made of?

What are Rhodophyta cell walls made of?

cellulose
The cell walls are made mainly of cellulose (but some species use xylan), and colloidal substances, such as agars and carageenan; and the cells may be multinucleated.

What type of algae are in phylum Rhodophyta?

red algae
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).

Why are Rhodophyta called red algae?

Rhodophyta is called red algae because of the presence of pigment phycoerythrin. This pigment reflects red light and absorbs blue light and gives the algae a red colour.

What is the habitat of Rhodophyta?

Rhodophyta are aquatic organisms that exist in both freshwater and marine habitats, although mostly marine. They are found in tropical, temperate, and cold-water environments. Rhodophyta tend to live at greater depths of water than Charophyta and Chlorophyta.

Why do some Rhodophyta have pit connections between cells?

Some species have pit connections between cells. In their research on cell wall composition on certain species of Rhodophyta, Youngs et. al. (1998) found that the cell walls of freshwater organism Bostrychia moritziana were highly adaptive to osmotic and ionic changes in their environment.

What is the cell wall composition of Archaebacteria?

Archaebacteria Cell wall Structure and Composition. The outer covering is the cell wall; a semi-rigid layer that maintains cell shape and chemical equilibrium. Peptidoglycan cell wall of eubacteria is absent. Cell wall chemicals are unique in archaebacteria and considerable differences are found in different groups.

How are Rhodophyta used in the medical field?

Rhodophyta have medical purposes. Turhani et. al. (2005) studied hydroxyapatite ceramic granule, which was calcified from red algae, to see if it would have potential for bone tissue engineering. Their objective was to determine whether or not living cells would grow on the granule.

What makes the Rhodophyta different from other algae?

The Rhodophyta are unique among the algae for having specialized pigments (phycoerythrin), reserve food (floridean starch), characteristic female reproductive organ (carpogonium), absence of any flagellate structure, and the sexual process.
