Question

What are cilia and flagella ?Write one similarity and one dissimilarity between the two of them.

Answer 1

Similarities include: 

1.  Cilia and flagella are both auxiliary parts of living cells.
2. 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. 

 

Answer 2

Cilia and flagella are cell organelles that are structurally similar but are differentiated based on their function & length.

Similarity : Both are used for movement.

Dissimilarity : cilia are small as compared to flagella  & numerous in number, whereas flagella is larger in size as compared to flagella & usually 1 to 8 in number.

Example : cilia in paramecium and flagella in euglena.
