general structure of algae

Their size ranges from microscopic to over 50 meters in length. The cell which is the basic unit of an organism is the center of all activities. Get ideas for your own presentations. They are Thallophytes which have chlorophyll as their primary photosynthetic pigment and lack a sterile covering of cells around the reproductive cells. Keshav Narayan Pai Msc I Department of Botany 2. 3. Characteristics• Range in size from microscopic to single celled organisms to large seaweed• Autotrophic• Form the reproductive structures – gametangia or gamete chambers• Aquatic and have flagella at some point in life• Often contain pyrenoids, organelles that synthesis and store starch Learn new and interesting things. 7 Amal Alghamd- Dr. Esmat 4/7/2014 AlgaeAn Overview 2. In this article, we will learn about the Cellular Structure of Algae with diagrams. Most have sporic meiosis, where meiosis produces spores … In addition, some algae are siphonaceous, meaning the many nuclei are not separated by cell walls. View Structure Of Algae PPTs online, safely and virus-free! In most algal cells there is only a single nucleus, although some cells are multinucleate. Algae lack the roots, stems, leaves, and other structures typical of true plants. The cells of blue green algae lack mitochon­dria. Based on the structural variations there are present different phyla or divisions of algae. Like bacteria the cell membrane invaginates to form a structure called the meso-some where the respiratory enzymes are loca­lized. Algae don’t have vascular tissues- non vascular plants. Algae – General Characteristics “The life of the planet began the long, slow process of modulating and regulating the physical conditions of the planet. There are two different patterns of algal cells, Prokaryotic (Blue green algae) Eukaryotic (Rest of algae) In algae the shape, size and form are variable in different members. Algae range in size from microscopic organisms, such as plankton that drift passively near the surfaces of oceans and freshwater bodies, to macroscopic seaweeds several meters long. Many are downloadable. The structural body of algae, either unicellular or multicellular, is called the thallus. Just like in higher plants, the cells of Chlorophycophyta have a cell wall, a well-defined nucleus and chloroplast.The majority of the members contain one chloroplast per cell. General characteristics of algae 1. Cell Structure of Algae. Algae are photosynthetic plants that vary in size and shape. The contents of this documents are Dichotomous Key to Freshwater Algae, Groups of Cyanobacteria & Algae, Dinoflagellates, Euglenoids, Brown, Golden brown, and Yellow brown Algae … The cytoplasmic membrane is the site of biochemical functions normally associated with the well-defined membranous organelles in eukaryotic cells. Share yours for free! Its dominant stage is the multicellular diploid stage. Some commonly known algae like Chlamydomonas, Volvox, and Spirogyra are members of Chlorophycophyta.Chlamydomonas is considered a typical green alga found in soils and freshwater … Variations in cell structure- unicellular, colonial, and multicellular. Algae - Algae - Form and function of algae: Algal cells are eukaryotic and contain three types of double-membrane-bound organelles: the nucleus, the chloroplast, and the mitochondrion. Algae’s general information ... Eukaryotic cell Eukaryotic cell has the structure as in typical cell of higher plants. Describe the general life cycle of BROWN ALGAE. The oxygen in today’s atmosphere is almost entirely the result of photosynthetic living, which had its start with the appearance of blue-green algae … Algae 1. Variations in pigments.
