What is responsible for the different colors of algae?
Beginning in the 1830s, algae were classified into major groups based on colour—e.g., red, brown, and green. The colours are a reflection of different chloroplast pigments, such as chlorophylls, carotenoids, and phycobiliproteins.
What molecules are responsible for the color of green red yellow and brown algae?
Chlorophyll is not the only photosynthetic pigment found in algae and phytoplankton. There are also carotenoids,and phycobilins (biliproteins). These accessory pigments are responsible for other organism colors, such as yellow, red, blue and brown.
Which pigment is responsible for red colour of red algae?
The pigments responsible for red colour of red algae are Phycobilins, Phycoerythin and Phycocyanin.
Why does brown algae appear brown and not green?
Most brown algae contain the pigment fucoxanthin, which is responsible for the distinctive greenish-brown color that gives them their name.
What causes the red color of red algae in their plastids?
The red line algae is an early branch of marine algae and has plastids that contain only one chlorophyll type – chlorophyll A. The pigment phycoerythrin , a pigment that reflects red light and absorbs blue light, is responsible for this algae’s red color.
What causes plants to have different colors?
Plants gain their coloration from the way that pigments within their cells interact with sunlight. Plants of different colors contain other pigments, such as anthocyanins, which are responsible for reds and purples; anthoxanthins, which reflect yellow; and carotenoids, which reflect yellow, orange, or red.
Which pigment is responsible for the green color of plants?
Chlorophyll
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.
What is the difference between red algae and brown algae?
Algae are classified into three groups based on the pigments they contain….Complete answer:
| Red algae | Brown algae |
|---|---|
| Flagella are absent in them. | Two unequal, lateral flagella are present in them. |
| They have a cell wall made of cellulose, pectin, and poly sulfate esters. | They have a cell wall made of cellulose and align. |
Which pigment is found in brown algae?
pigment fucoxanthin
Most brown algae contain the pigment fucoxanthin, which is responsible for the distinctive greenish-brown color that gives them their name.
Which microbes are responsible for the red Colour of red Sea?
Today, it is widely accepted that the Red Sea is named for an occasional bloom of the cyanobacteria, Trichodesmium erythraeum algae, which clouds and muddies the usually translucent blue-green waters. These cyanobacteria appear as red and pinkish blankets on the surface of these waters.
What gives red algae its color?
Red, green, and brown algae have different types of pigments which give them their color. (Brown algae gets its color from the xanthophylls pigment fucoxanthin, red algae get their color from phycoerythrin, green is from chlorophyll.) These pigments have a certain chemical structure that allows them to absorb light.
What are the different types of brown algae?
In addition to kelp, other examples of brown algae include rockweed (Ascophyllum nodosum) and Sargassum (Fucales) . There are more than 6,000 species of red algae. Red algae gain their often brilliant colors thanks to the pigment phycoerythrin.
What are the different types of pigments found in algae?
Ø Many coloured pigments such as green, red, yellow, and blue have been found in marine and freshwater algae. Ø Different groups of algae have different and specific pigment composition. Ø Pigments are usually found in specialized plastids called chromophores in all groups of algae except in the members of Cyanophyceae (blue green algae).
What are the characteristics of photosynthetic algae?
Ø They absorb blue green, green and yellow light and transmit red light. Ø All photosynthetic algae contain chlorophylls, carotenoids and Xanthophylls. Ø Members of Cyanophyceae (Myxophyceae = blue green algae) and Rhodophyceae (red algae) contain large amount phycobilins, particularly phycocyanins.
