General Characters 5. Habitats are also defined by the distribution of a community, which is a collection of organisms. New to Target Study? There are about 30,000 Species of Algae. (i) Epiphyllophytes: Such algae are epiphytic upon leaves of trees. 0000002476 00000 n What is the 'Study or Science of Algae' known as? Geographical Range and HabitatThey are distributed worldwide in the sea, in freshwater and in waste water. These organisms can thrive in freshwater lakes or in saltwater oceans. There are about 600 Species which include Bumilleriopsis, Tribonema and Vaucheria. 114 0 obj<> endobj Many algae consist of only one cell, while the largest have millions of cells. 0000000956 00000 n Thermophilic Algae - These live in hot springs. 0000058867 00000 n 0000003888 00000 n They are also capsoid, coccoid, amoeboid, filamentous, parenchymatous, or plasmodial. In Air Salobar and Halong, … Filamentous algae are usually considered as ‘macrophytes’ since they often form floating masses that can be easily harvested, although many consist of microscopic, individual filaments of algal cells. Bryon = mass; phyton = plant), a division of kingdom Plantae comprises of mosses, Hornworts and Liverworts. The distribution of algal species has been fairly well studied since the founding of phytogeography in the mid-19th century. These may be included in the Chrysophyceae or in the Protozoan group Zoomastigophora.Class Chrysophyceae (golden algae) - These are mostly Unicellular or Colonial Flagellates. Algae are also known as 'Sea-Weeds', 'Pond-Scum' and 'Grasses of Water'. 0 The effect of light on the distribution of algae has already been considered. trailer Class Charophyceae - It includes the macroscopic Pond Weed Chara, filamentous Spirogyra and Desmids. <<18bb7b21dec618418ce66077dc6da239>]>> Sign Up to get started. ��G)z�����az�n�}��ge~VI��HT�0vd��@Q�-m��3)��Q���E�8�1R��A+8���r#�5��Ql�a_�����ʞ�S�N�w�89�TN)��Ɵ�Ɩ��IVX��"š(I�%9��*+�"��ϳ3\�n;p선� 曌�������^e��z�e�D���S[���p�;R�ػi��wS����#V�{3��:��^��& �'���7u���4��1��a������X������ꂾ�>ef-�=xA�OXzAc�3�O&�rj��%ЧpH Distribution. �K���C��͌$���I����a�ÑG Their body is unicellular, colonial, or multicellular. %%EOF There are about 12,000 to 15,000 living Species. Microscopic spherical Algae (Eosphaera and Huroniospora) that resemble the living genus Porphyridium are known from the Gunflint Iron Formation of North America (formed about 1.9 billion years ago). In many members ejectile Trichocysts are below surface. These eukaryotic cells do not have flagella and centrioles, unlike other types of algae. Several produce toxins that either kill Fish or accumulate in Shellfish and cause sickness or death in humans when ingested. In the first stage, each cell has a single set of chromosomes and is called Haploid, whereas in the second stage each cell has two sets of chromosomes and is called Diploid.Importance and Uses of Algae, Education India, Colleges, Universities, Courses, Exams, Schools. Origin and Evolution of Algae Extracts from the cell walls of (typically brown & red) Algae provide the Polysaccharides Agar and Carageenan. Green algae have cell walls made of cellulose and are photosynthetic. There are more than 1,200 Species described, most in the class Dinophyceae; Alexandrium, Dinophysis, Gonyaulax, Peridinium and Polykrikos. Hamed Botany Department, Faculty of Science, Ain Shams University, Cairo, Egypt. Their Habitats range from Tropical Forests to Deserts. Habitat and Distribution Red algae are found around the world, from polar waters to the tropics, and are commonly found in tide pools and in coral reefs . Class Prymnesiophyceae (Haptophyceae) - These are predominantly marine and planktonic. The best characterized fossils are the coralline red Algae represented in fossil beds since the Precambrian time (from about 3,800 million years ago until 544 million years ago).ReproductionReproduction in Algae occurs in both asexual and sexual forms. They are predominantly freshwater. ��0�ts�|����t��^a���X����lO�ܑ�À*���+��2�`���i�͸��nr+^V��� �Q������t-�i{����5���}�������>�e�ml����y�?G\��'U��_�+�&{Or�hB�2H�f���K������? habitat quality can greatly aid habitat selection (Monkko-nen et al. The study aimed to establish the importance of different algae … All trade marks belong to the respective owners. Endosymbionts - Some Algae live inside other organisms, and in a general sense these are called Endosymbionts. There are at least 1,500 Species. Algae have many types of life cycles, and they range in size from microscopic Micromonas species to giant kelps that reach 60 metres (200 feet) in length. Few algae (Chara, Caulerpa) can obtain a foothold in loose sand or mud, and a rock on a sandy … H��TM��0��+�hK�������3�n^� �D�t�����)��@b���yo,������r�K�G�����3��s%4k���+)JF�1F�#�kQ� o�e�x^Q�xYs�#�J��;�p��6�3U��� ���u�T���[,�8��y)��²��+aLa� ��m�� Ye���}?ƣ�t�b�/�O�Z��Zf|��WX�p�gDe��~�@)��˭IZ�2���a|��p��Q?�!���X�ž�>x�u)c�⇒��y��E���}�B�+W���{� }A>��x$��X���|�h� �K�Q�u9׊��/�zNx�mi�8��+"یC���E�/Mc ��|�*h'l��������J�VF�E��L�S)C��:j�jΙ�#��A�v-V�b��N�b��"�+�����uOm��L~X�ε�V��adH�������I(1$~��L 0000001962 00000 n They also occur upon rocks and fencing wires.
