Description

Name: 1. Fucus vesiculosus 2. Kingdom: Chromista Phylum: Ochrophyta Class: Phaeophyceae Order: Fucales Family: Fucaceace Genus: Fucus Species: F. vesiculosus 3. It is Eukaryotic 4. It is multicellular 5. It contains Chlorophyll a & c 6. Fucoxanthin is the accessory pigment that Description: 1. The F. vesiculosus contains a true nucleus and has Chlorophyll a & c. The Fucus has a root-like structure called Holdfast that makes sure the organism is attached to a rock or the ground. The stem-like structure found in F.vesiculosus is called Stipe. It has leaflike structures called Blades that absorb sunlight and also carry the reproductive parts. The Bladders are a special feature found in pairs on its blades. These air bladders help the organism float upright in the water. 2. The organism is attached to the pebbles and dense rocks by a root-like structure called a holdfast. This is the reason why there is no motility. 3. F. vesiculosus has blades coated with slime to prevent the attachment and harm of other small

Brown Algae Report: Fucus vesiculosus By: Puneet Gidda Blk: B

Reproduction: F. vesiculosus produces its gametes only in spring and summer. Reproductive areas are located at the tips of the blades, called Conceptacles. Sperms and eggs are produced in Conceptacles and released into the water. The sperm cell then fuses with the egg and a zygote is formed. The zygote then goes through mitosis and grows into a new diploid sporophyte. 2. In F. vesiculosus the egg is larger than the sperm so two gametes are different from each other that's why it is Heterogamy. The fusing of the male and female gametes is called Habitat: 1. F. vesiculosus is found in the sea mostly in the North Atlantic and Pacific seas. The Fucus comes from temperature water with low salinity. 2. The organism has a structure called a holdfast which acts as an anchor to keep it in place in the water. Also, it has another structure known as a bladder that is filled with air and allows it to float over water. The blade is a very flat leaf-like structure that absorbs the sunlight

Benefits:  Facts:    

 

Fucus extract helps reduce blood sugar levels. Due to high Iodine contents in the algae. Also known Bladderwrack It is used to as cure thyroid disorder They grow between 2-50 cm long F. vesiculosus contains chlorophyll c which is why it is not in kingdom Plantae. Has a lifespan of 4-5 years Able to protect some organisms by using the thalli of the fucus that covers them
