Seaweed Botanical nature

Seaweed, Thallophyta division, is a sea of ​​plants including algae and multicellular algae. Seaweed is not perfect because the plants do not have roots, stems and leaves. Morphology seaweed species Glacilaria called thallus, which has no real difference between the roots, stems and leaves, seaweed grows well on the sea floor can still be penetrated sunlight. Chlorophyll like ordinary plants and also other pigments. Where these pigments that distinguish between the types of seaweed. Seaweed is grouped into four classes based on the content of the pigment, which Rhodophyceae (red algae) m Phaeophyceae (brown algae), Chlorophyceae (green algae) and Cyanophyceae (blue-green algae). While commonly cultivated species of grass is Eucheuma, Hynea, gracillaria and Gelidium and Sargassum. The growth and spread of seaweed influenced by several factors, such as oceanography (physics, chemistry and dynamics of the sea) and the type of substrate essentially. For growth, seaweed take nutrients from the surroundings by diffusion through the wall of his thallus.
Breeding can be done in two ways, namely by mating between male gametes and female gametes (generative) and unmarried via vegetative spores konjugatif and dissemination of spores contained in the bag. Seaweed is widely used as an industrial raw material. For example, brown algae, which are used as raw material for ice cream, textile processing, pharmaceutical factory, shoe polish and paint factory. Red algae feedstock for the food industry, pharmaceutical, leather tanning and brewer. Seaweed also can be used as material for fertilizer, animal feed mixtures and cosmetic raw materials.
