Are cilia and flagella found in every cell?

Answer 1

No, cilia and flagella are not found on every cell.

Cilia can be found:
1) on many organisms within the ciliate group of protists (single celled eukaryotes) eg: paramecium. These usually give the cell motility, but can also be for moving food.
2) on certain cells of animals and humans, eg: respiratory epithelial cells and cells in female fallopian tubes. These serve to function the entire organism (eg: clearing mucous)
3) on some plant cells, eg: within the division Cycadophyta. These are for motility of gametes.

Flagella can be found:
1) on many organisms within the flagellate group of protists (single celled eukaryotes) eg: euglena
2) on certain cells of animals and humans, eg: sperm.
3) on some bacteria species (prokaryotes) eg: Salmonellaenterica
Flagella give a cell motility.

Answer 2

Cilia and flagella are the primary means of locomotion in unicellular organisms. These propulsion mechanisms are tightly packed together in arrays.

Answer 3

Yes!! Cilia and flagella are unicellular organisms main source of locomotion (movement), they help propel the cell/organism

Answer 4

propulsion, with movement a single celled organism can move to a different environment more abundant in food, away from toxic areas, meet a potential mate, etc.
