2.1 Complete the table below. Volvox Spirogyra Diatoms Polysiphonia Euglena Reproduction Locomotion 8 Photosynthetic pigments Niche 2.2 Describe the movement of a Volvox colony and the unicellular Euglena. Polysiphonia which is a green algae has photosynthetic pigements chlorophyll a,b, caroteinoids. Red algae are called so because of their reddish color due to the presence of special pigments r-phycocyanin and rphycoerythrin.
As a red-colored plant, Polysiphonia is well suited to absorb the green and blue-green light that typically penetrates the deeper sea water where these red algae thrive. photosynthetic pigments of some red seaweeds and different seasons. RESULTS TAXONOMIC DESCRIPTION OF THE TESTED RED SEAWEEDS The five species of Rhodophyta collected from Abu Qir Bay were identified as: Corallina elongata Ellis et Solander, Corallina officinalis Linnaeus, Jania rubens (Linnaeus) Lamouroux, Polysiphonia elongata (Hudson) Sprenge and Occurrence of Polysiphonia: Polysiphonia is a large genus with about 200 species. The genus is represented in India by about 16 species found is southern and western coasts of India. Some common Indian species are P. ferulacea, P. urceolata and P. variegata.

They also supplement photosynthetic pigments that absorb light energy in the blue region. Defensive role of pigments [ edit ] It's known that animals use their color patterns to warn off predators, however it has been observed that a sponge pigment mimicked a chemical which involved the regulation of moulting of an amphipod that was known to prey on sponges.

The central siphon is surrounded by 4–24 pericentral siphons. Polysiphonia is commonly found as an epiphyte on plants and lithophyte on rocks in brackish estuaries in the intertidal and Polysiphonia, a common genus of marine red algae, is red in color because of the pigment phycobilin, which masks the green color of the chlorophyll responsible for photosynthesis. As a red-colored plant, Polysiphonia is well suited to absorb the green and blue-green light that typically penetrates the deeper sea water where these red algae thrive. photosynthetic pigments of some red seaweeds and different seasons.

Phycoerythrin is a group of red photosynthetic pigments present in red algae and some cyanobacteria. Polysiphonia is a type of red algae. Euglena - is a group of protozoan, Chlamydomonas - is a group of green algae, Fucus - is a group of brown algae. So, the correct answer is (B). Polysiphonia.
