Question

do flagella of eukaryotes have hook like prokaryotes? I am confused cauz some teachers ar saying that they r having but some are denying

Answer 1

Flagella and Cilia are fine vibratile hair like membrane covered protoplasmic outgrowths that occur on the free surface of the cells and take part in producing a current in fluid medium for passage of materials and locomotion. Flagella are longer but fewer(generally 1-4). Flagella occur  in group flagellate or protozoan protistans, euglenoids, dinoflagellates, choanocytes of sponges, gastrodermal cells of coelenterates, sperms of animal bryophytes and several pteridophytes, zoospores and gametes of several algae and primitive fungi.
