What are cilia and flagella ? Write one similarity and one dissimilarity between the two of them.
Answers
Similarities include:
Cilia and flagella are both auxiliary parts of living cells.
They can both be used for movement.
Differences include:
1.Flagella are longer in size while cilia are shorter.
2.Cilia contributes in the prevention of dust accumulation in breathing tubes by simply creating a thin layer of mucous in the tube while the flagella mainly uses sperm cells to move and propel.
3.Cilia use ‘kinesin’ which has an ATPase activity that produces energy to perform the movement while the flagella are powered by the proton-motive force by the plasma membrane.
4.Cilia moves like the breast stroke in swimming while the flagella moves in an oar-like style.
5.Cilia are present in multi-cellular organisms and help in moving fluids past an immobile cell while the flagella are mainly found in gametes.
