What are cilia and flagella? Name the organisms in which these are present.
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:
Cilia and flagella are motile cellular appendages found in most microorganisms and animals, but not in higher plants. In multicellular organisms, cilia function to move a cell or group of cells or to help transport fluid or materials past them.
Cilia are present in organisms such as paramecium while flagella can be found in bacteria and sperm cells. Cilia and flagella are the most common organelles for locomotion in unicellular organisms.
