Axopodia
Axopodia (pronunciation: ax-o-po-di-a) are long, thin extensions of the cytoplasm found in certain protists, especially those in the class Actinopoda. They are supported by microtubules and are used for feeding and locomotion.
Etymology
The term "Axopodia" is derived from the Greek words 'axios' meaning 'worthy' and 'podia' meaning 'feet'. This term was first used in the late 19th century to describe the unique structures found in certain protists.
Structure and Function
Axopodia are slender, hair-like protrusions that extend from the cell body of certain protists. They are composed of a central core of microtubules surrounded by a layer of cytoplasm. The microtubules give the axopodia their rigid structure, allowing them to extend and retract as needed.
Axopodia are primarily used for feeding. They extend out from the cell body to capture food particles, which are then transported back to the cell body for digestion. In addition to feeding, axopodia also play a role in locomotion. By extending and retracting these structures, protists can move through their environment.
