What Plant Is Sea Lettuce? A Comprehensive Guide to Sea Lettuce

I wonder if you have heard of sea lettuce. Today, the editor will introduce to you what plant sea lettuce is.

Sea lettuce is a thin, flat green algae plant with a holdfast. Its edges are sometimes split into ruffled lobes. Its blades usually grow to 18 cm or longer, and up to 30 cm in cross-section. It is a soft, translucent thallus two cells thick. It has no stipe and usually attaches by means of a disc-shaped holdfast. The color ranges from green to dark green, and the phyllotaxy is irregular. Its chloroplasts contain 1-3 pyrenoids arranged in a cup shape. Other plants in the genus Ulva also share similar characteristics.

Sea lettuce contains a relatively high amount of protein and also contains more than 20 kinds of amino acids essential to the human body, especially rich in methionine. Health benefits: sea lettuce has a remarkable weight-loss effect, can also make dry skin soft and smooth, control oil secretion in oily skin, maintain the healthy growth of epithelial tissue, and reduce pigmented spots; in addition, seaweed foods including sea lettuce can selectively remove carcinogens such as mercury, cadmium and lead from the human body.
