if it can be more than one, it would be the nucleus and cytoplasm, if not, then nucleus because it is an extreme outlier.
You may be talking about microvilli.
The folds of the cell membrane on the free surface are known as microvilli. These folds will help in increasing the surface area of the cell membrane.
microvilli increase surface area for absorption
cytoplasm is located between the cell membrane and the nucleus.
Microviili increase the plasma membrane surface area. They are generally found in absorptive cells. (e.g. intestinal cells)

The core of microvilli is attached to the plasma membrane. It also contain a bundle of about 40 filaments of actin.
