Phaeophyceae – Brown Algae. It appears textured but it’s holes are not openly visible. Its cells are normally as broad as they are long, and they thrive in the low temperatures of spring and winter. Vegetative, Asexual, and Sexual Reproduction. Rating. They show great variation in size and form. Sometimes, these filaments develop root-like structures for attaching themselves to the substrate. Which of the following is also known as pond silk (a) Ulothrix (b) Spirogyra (c) Nostoc (d) Anabaena. s. Get an answer. Spirogyra is a filamentous alga. For the paramecium to move backward, the b) Photosynthetic organism synthesizing their own food. Ulothrix is a genus of green algae in the family Ulotrichaceae. Vegetative reproduction happens through fragmentation of the filaments. Log in for more information. English words similar to 'oedogonium': otoconium. Diatoms and Vaucheria Euglena are unicellular protozoans that almost always have chloroplasts. Ulothrix - They are green, filamentous algae, mostly found in freshwater with low salinity areas like; ponds, lakes etc. In vegetative reproduction, fragmentation takes place, and Spirogyra simply undergoes intercalary cell division to extend the length of the new filaments.. a) Chlorophyll absent. *Response times vary by subject and question complexity. Spirogyra, Ulotrix, and Oedogonium are all filamentous. The members of phaeophyceae or brown algae are found primarily in marine habitats. Green Algae: Green algae are eukaryotes. Median response time is 34 minutes and may be longer for new subjects. In algal cell wall, different chemical components are present which vary widely among different groups (e.g., xylan, mannan, galactan, alginic acid, silica, agar, pectin, carrageen in, etc.). ; Spirogyra - They belong to the largest group of green algae and are commonly found in freshwater bodies like; deep ponds, rivers etc. English. palak1114 palak1114 05.02.2019 Biology Secondary School Distinguish between Reproduction of planaria and Spirogyra 1 See answer palak1114 is waiting for your help. The photosynthetic pigments (chlorophylls a and b, carotene, and xanthophyll) are in the same proportions as those in higher plants. Motility-The paramecium swims by beating the cilia. Physics. The genus Spirogyra comprises more than 300 species and most of them are free floating algae. 1. Spirogyra. 8. Maths. In Spirogyra, the sexual reproduction involves a cycle alternation between a haploid vegetative filament (gametophyte plant) and a diploid zygospore, towards the end of growing season the Spirogyra filament produce aplanogametes in vegetative cells called gametangia The gametes fuse to form a zygospore (2n). The paramecium moves by spiraling through the water on an invisible axis. Ulothrix is a genus of non-branching filamentous green algae, generally found in fresh and marine water. Log in. Question. Books. The difference between spirogyra and Euglena is that: Euglena is a freshwater protist. Euglena Chlorophycophyta (the green algae) – ex. Asked by Wiki User. A somewhat similar parasite was found by Sparrow (I936") in Spirogyra, site 3, Cam- bridge, but no zoospores were observed. Log in for more information. They are commonly found in marine water bodies. Green Algae: Green algae refer to any green color algae found in freshwater habitats. A protein rich blue-green alga is 1) Chlorella 2) Spirulina 3) Spirogyra 4) Ulothrix (Difference Between Chlamydomonas and Spirogyra) The key difference between Chlamydomonas and spirogyra is that Chlamydomonas is a single-celled spherical-shaped green alga … Diagram the life cycles of Chlamydomonas, Ulothrix, Spirogyra, and Oedogonium; indicate where meiosis and fertilization occur in each. However, some species like S. rhizopus, S. dubia etc are found attached to substratum by the means of rhizoids. The cells which produce gametes are called gametangium.
