Flagella physical features
WebBrown algae are a group of algae belonging to class Phaeophyceae. They are named due to their colour, which varies from brown to olive green. They are mostly found in marine environments. There are around 1500 species of brown algae, which vary greatly in their size and shape. They are multicellular and the colour depends on the ratio of ... WebIn flagella and motile cilia, motor proteins called dyneins move along the microtubules, generating a force that causes the flagellum or cilium to beat. The structural connections between the microtubule pairs and the coordination of dynein movement allow the activity of the motors to produce a pattern of regular beating 5 , 6 ^{5,6} 5 , 6 ...
