Amoebocytes
Definition
Amoebocytes are versatile cells found in sponges that play key roles in digestion, reproduction, and transport of nutrients. They can also transform into other cell types as needed.
5 Must Know Facts For Your Next Test
- Amoebocytes are crucial for distributing nutrients from choanocytes to other cells in the sponge.
- They can differentiate into other cell types, such as sperm cells or spicules.
- Amoebocytes move through the sponge's mesohyl using pseudopodia, similar to amoeba movement.
- They play a role in the sponge's immune response by engulfing and digesting bacteria and debris.
- Amoebocytes help in the formation of spicules, which are structural elements that provide support to the sponge.
