What is Undaria

Undaria pinnatifida mainly relies on its leaves to absorb nitrogen, calcium and phosphate from seawater and other nutrients necessary for growth, and then in the body for synthesis and utilization of transformation.

Mention of Undaria pinnatifida, we may be a little strange, but in fact we often eat in our daily life. below we will give you a brief introduction of wakame.

Undaria pinnatifida is a seaweed plant, annual, yellow-brown in color, 1-2m high, 50-100cm wide, with green leaves and pinnate lobes, thinner leaves than kelp, and looks like a big broken sunflower fan and also like a skirt, so it is named. There are two kinds of light dry and salty dry. Undaria pinnatifida is a seaweed of the kelp family, known as a vegetable in the sea.

The internal structure is very similar to the kelp, in the growth of the sporophyte stalk on both sides, the formation of agaric-shaped overlapping folds of the spore leaf, mature, the formation of sporangia on the spore leaf. The life history of Undaria pinnatifida is very similar to that of kelp, and it also alternates from generation to generation, but the growth time of sporophyte is shorter than that of kelp, close to one year (kelp grows nearly two years), while the growth time of gametophyte is longer than that of kelp, about one month (kelp gametophyte grows only for two weeks).

Undaria pinnatifida mainly relies on its leaves to absorb nitrogen, calcium and phosphate from seawater and other nutrients necessary for growth, and then in the body for synthesis and utilization of transformation. In addition, in terms of the type of cellulose synthesized by photosynthesis, it is different from the cellulose, hemicellulose, pectin, etc. of land plants. The main products of Undaria pinnatifida photosynthesis are alginic acid and alginan polysaccharides. These polysaccharides have good effects in lowering cholesterol, lowering blood pressure and preventing adult diseases. Another major feature of nepotism is that its reproductive mode is completely different from that of land plants. For example, in terrestrial higher plants, offspring are produced by pollination between male and female stamens after flowering. But Undaria pinnatifida can't flower, but rely on swimming spores to reproduce.
