Answers
Answer:
Protozoans belonging to the phylum Ciliophora are covered with cilia, while flagella are a characteristic of the protozoan group Mastigophora. In eukaryotic cells, cilia and flagella contain the motor protein dynein and microtubules, which are composed of linear polymers of globular proteins called tubulin
Explanation:
Answer: Cilia and flagella are cell organelles having similar structure but differ in their function and length. Cilia are short in size and are present in large number in the cell. On the other side, flagella are longer in size and are few per cell.
Cilia has slender, microscopic, short hair like structure whereas flagella have long hair like filamentous cytoplasmic complex structure. Both are the most common organelles and have locomotive structures. They are found in unicellular organisms. They also help in processes like respiration, circulation, excretion, etc.
Cilia and flagella are found in eukaryotic cells whereas, flagella are also present in prokaryotic cells. Cilia are found in paramecium organism and flagella are present in bacteria and sperm cells.
