Algae can grow in most parts of the world however to be profitable only certain regions with adequate weather conditions can be considered.
What are the parts of algae?. According to the Whittaker scheme algae are classified in seven divisions of which. Algal cells are eukaryotic and contain three types of double-membrane-bound organelles. The eukaryotic algae possess membrane-bound organelles such as nuclei mitochondria and plastids.
In general algae are plant-like organisms that are subdivided into two parts photosynthetic and aquatic. A number of things stagnant water movement high temperatures andor an influx of nutrient material such as lawn fertilizers could have contributed to the explosive growth of algae to form this thick green mat. The production of algae-based fuel is still a relatively new technology.
Algae cell-wall consists of two layers. Algae or alga singularly belonging to the kingdom Protista are largely aquatic organisms that are typically fully photosynthetic but differ from plants in that they lack true roots stems leaves and gametes the male and female parts of plantsAlgae can vary in size from less than two micrometers in the case of micromonas a species of green algae to over 200 feet. Nevertheless it is widely accepted because of the photosynthesis as the mutual characteristic to interpret algae as lower plants in distinction to the vascular higher plants.
The right-side picture below shows Brookmill Park Lake again 11 months later in September 2009. In most algal cells there is only a single nucleus although some cells are multinucleate. The cyanophycean cell possesses a surface layer of gelatinous sheath which is a constant feature although it varies in thickness Figs.
In some places algae would have to be cultivated indoors further increasing costs and the price of the product. In most algal cells there is only a single nucleus although some cells are multinucleate. Based on type of the cell algae can be grouped basically into two major assemblages prokaryotic and eukaryotic algae There are four distinct groups within the algae Group 1 Prokaryotic algae include two divisions.
Inner microfilamentous and outer gelatinous irregular layer. In addition some algae are siphonaceous meaning the many nuclei are not separated by cell walls. Many vitamins and minerals like vitamin A C B1 B2 B6 niacin iodine potassium iron magnesium and calcium are abundantly found in algae.
Hence these are also called nitrogen-fixing bacteria. It also contains other substances like alginic acid calcium carbonate fucoidan fucin silica etc. Blue-green algae that contribute greatly to the fertility of rice fields are species of Aulosira Anabaena Tolypothrix Cylindrospermum Nostoc and Mastigocladus.
224 B Holdfast part of the thallus that anchors the plant to the bottom rock sand coral rubble other plants or animals. Group 2 Eukaryotic algae with chloroplasts surrounded only by the two. Algae are a rich source of carbohydrates protein enzymes and fiber.
Algae are eukaryotic organisms and contain three types of double-membrane-bound organelles. In addition algae may occur in moist soil or on the surface of moist rocks and wood. Chemically the cell wall is composed of cellulose pectin mucilage like a carbohydrate.
The nucleus the chloroplast and the mitochondrion. These include dams rivers reservoirs creeks lakes and oceans. Ecologically some species of blue-green algae are significant to the environment as it fixes the nitrogen in the soil.
Unicellular algae occur most frequently in water especially in planktonPhytoplankton is the population of freefloating microorganisms composed primarily of unicellular algae. Although it is a plant like organism still it does not have true roots stems leaves and vascular tissue but possess the simple reproductive structures. Algae live with fungi in lichens.
Filaments or filamentous very thin branches that are usually chains of connected single cells Fig. The nucleus the chloroplast and the mitochondrion.
