Renette cells

Definition

Renette cells are specialized excretory cells found in some nematodes. They play a crucial role in osmoregulation and waste removal.

5 Must Know Facts For Your Next Test

1. Renette cells are involved in the excretion of nitrogenous waste in nematodes.
2. These cells help maintain osmotic balance by regulating water and ion concentrations.
3. Renette cells are located in the anterior part of the nematode's body.
4. They release their contents through a pore called the excretory pore, which opens to the exterior of the nematode.
5. The function of renette cells is analogous to that of kidneys in higher organisms.
