a large order of cellular, flowerless, cryptogamic plants, found in the sea (seaweeds), in rivers, laked, marshes, hot springs, and moist places, all over the world. They consist of a brown, red, to green. Flattered, cellular, leaf-like expansion, called a thallus, sometimes stalked, which bears the organs of reproduction. Some have root-like processes by which they are attached to rocks. These do not act like the nourishing roots of flowering plants; they simply fix the plants and enable them to sway about in the water. This is markedly the case with the Laminaries, or large tangles of our coasts. The leafy appendages of seaweeds are called fronds. They vary in size, colour, and consistence. Some of the red and green delicate fronds form beautiful objects when carefully dried and laid out on drawing-paper. In order to dry seaweeds they must be first washed carefully in fresh water to separate saline matters, and then placed within drying-paper and subjected to pressure. Very delicate seaweeds should be floated out in water, drawing-paper being placed under them, and their fronds being carefully arranged on the paper before they are raised out of the water. They must then be dried partially in the air, and afterwards under pressure between sheets of drying paper.
Seaweeds are composed entirely of cells, which in some instances become elongated so as to have the appearance of tubes. Some Algae are uni-cellular, that is, are composed of a single cell, as occurs in some Desmidiease, as Closterium. At other times they are composed of numerous cells, which are kept together by a gelatinous matter, but separating easily from each other so as to have an independent existence. This is observed in the red snow plant (Protococcus or Palmella nivalis). The cells of seaweeds are sometimes joined together so as to form a linear series, and to give them a thread-like appearance; and in such a case, when the divisions between the cells are marked, the whole appears like a beaded necklace of cells. When the cells are united both lengthwise and laterally they then form an expanded flat frond. In some instances the frond is gelatinous.

What is the kingdom of red algae?
Red algae belong to the kingdom Protista. They are multicellular, photosynthetic organisms that typically live in marine environments. Red algae have a range of forms and sizes, from simple filamentous forms to large, complex seaweeds.
What do red algae eat?
fish...
Algae are classified according to their?
Algae are classified according to their pigmentation, cell structure, and method of reproduction. They can be grouped into divisions such as Green Algae, Red Algae, and Brown Algae based on these characteristics.
Red sea is named after the algal bloom of what?
The Red Sea is named after a type of algae called Trichodesmium erythraeum. This algae can form large blooms in the water, giving the sea a reddish-brown hue.
Why do biologists classify red and green algae with land plants?
Red and green algae are photosynthetic and are thus autotrophs. Otherwise, they are aquatic and (in the case of green algae) can be unicellular. But these are similarities that are not sufficient to define algae as true plants. All plants in the Kingdom Plantae are multicellular and terrestrial (ancestrally terrestrial in the case of waterlilies). Green algae are important in the study of plants as they show the base of the plant kingdom, hinting at what a common ancestor to the whole kingdom may have looked like. In particular, the charophytes are probably close to the common ancestor of all land plants. Thus, in the study of land plants, green algae can be considered the most recently diverged outgroup. And, earlier still, red algae diverged.
Does red algea move?
It does move,because of the ocean waves moving 24-7... It makes the red algae move.
Can red algae move?
they dont unless moved by something elss
What type of protist have chloroplast?
Algae: Green algae, even red algae but phycoerythrin over populates it which gives the red algae its red color.
Are red algae and red marine algae the same?
Yes, red algae and red marine algae refer to the same group of algae that are predominantly found in marine environments. They are known for their red pigmentation due to the presence of phycoerythrin pigments.
Is red mineral algae and red marine algae the same?
no
Is Red tide is caused by green algae?
red algae.............
What causes red algae to be red?
Red algae contain red pigments called phycoerythrins, which are responsible for their characteristic red color. These pigments help the algae absorb certain wavelengths of light that penetrate deeper in the water column, allowing red algae to thrive in lower light conditions compared to green algae.
Does the red algae effect the red sea?
the algae does affect it. the algae is a little monster that comes out and eats people.
Is agar red algae or green algae?
Red algae cell walls contain agar. while green algae cell walls contain cellulose Answer 2 Agar is a chemical obtained from walls of certain red marine algae .It is not Algae itself .
Do green algae move?
Green algae don't move. Unless moved when bumped into by other organisms, they do not move at all.
Most of the worlds seaweed is what algae?
red algae
What kind of algae are seaweeds that most often occur in warm marine waters?
