Amoebocytes
Definition
Amoebocytes are mobile cells found in the mesohyl of sponges. They play crucial roles in digestion, nutrient distribution, and structural support.
5 Must Know Facts For Your Next Test
- Amoebocytes can differentiate into other cell types such as sclerocytes and choanocytes.
- They transport nutrients from choanocytes to other cells within the sponge.
- Amoebocytes are involved in producing spicules and spongin fibers, which provide structural support.
- They help in the digestion process by phagocytizing food particles captured by choanocytes.
- Amoebocytes contribute to the sponge's ability to regenerate lost parts.
