Plants climb or creep on the nearby trees and walls and try its level best to survive on this planet for a lengthy period of time. Some creepers occupy major portions of the land while some occupy only minor portions. Some fast growing creepers like money plant are grown inside the garden as an ornamental plant since it brings luck and beauty to their houses. This topic will deal with a seaweed named sea lettuce which is a green algae found in bays and rocky areas around the world. This falls under the Phylum Cholorophyta and the botanical name of this plant is Ulva lactuca.
This wonderful plant is found in Europe, North America, Central America, Caribbean Islands, South America, Africa, Indian Ocean islands, South-West Asia, China, Pacific Islands, Australia, and New Zealand. This seaweed is naturally found in sheltered or moderately exposed rocks and shores, pool areas, shallow water, brackish waters and grows rapidly. The seaweed is found abundantly in Irish shoreline. This seaweed grow attached to without a stripe, to rocks, other seaweeds and various substrates, by a disc shaped holdfast.
The fronds within the water resemble lettuce leaves, hence the name Sea Lettuce. Plants tend to be pale green when young, bright green when mature and dark green when old. This seaweed grows wonderfully in high and low intertidal zones where the water is 75 feet deep. This seaweed grows perennially and blooms more in the summer. This sea lettuce which is bright green in color has lobed, ruffle-edged leaves that are coarse and resemble a leaf of lettuce. The leaves may appear flat, thin, rounded or oval. These seaweeds are largely found where the sewage runoff is very heavy.
- Like lettuce grown on land, the sea lettuce can be used in salads and soups.
- Sea lettuce is used to make lip smacking ice creams and other food products.
- This seaweed grows to a height of up to 2 ft.
- Sea lettuce is a common green seaweed with a broad translucent frond that is just 2 cell layers thick.
- It attaches to the substratum with a small disc-like holdfast, but in sheltered areas it may detach and live as large free-floating masses.
Most of seaweeds are washed up on beaches where their decay becomes methane, hydrogen sulfide, and other gases. In the year 2009, large volumes were washed up on the beaches of Brittany, France. When large quantities of sea lettuce decay in the sea, it generally become threat to the human beings since these decayed materials will have dangerous toxic substances as mentioned above.
