cell is smallest organ of all living organism we can't see cell through the neck eye.
I think you are refering to the cilia of a cell.
Cilia are the cell organelles that sweep material across a surface. They are hair-like structures that protrude from the surface of some eukaryotic cells and beat in a coordinated way to move materials along the cell's surface.
Mitochondria are the cellular organelles that contain cristae, which are the folded inner membranes that increase the surface area for biochemical reactions. They are responsible for converting nutrients, such as proteins, carbohydrates, and fats, into adenosine triphosphate (ATP) through the process of cellular respiration. This process occurs mainly in the mitochondria's inner membrane, where the electron transport chain and ATP synthase are located.
Organelles with many convolutions include the endoplasmic reticulum (ER) and mitochondria. The rough ER has ribosomes on its surface and extensive folding to increase surface area for protein synthesis, while the smooth ER is involved in lipid synthesis and detoxification. Mitochondria have inner membrane folds called cristae, which enhance their ability to generate ATP through cellular respiration. These convolutions maximize the organelles' functional capacities.
Cilia.
Cisternae are flattened membrane-bound sacs found in organelles like the endoplasmic reticulum and Golgi apparatus, which increase surface area for cellular reactions. By providing extensive surface area, they facilitate the accommodation of more enzymes and proteins necessary for various biochemical processes. This structural configuration enhances the efficiency of metabolic activities and transport within the cell, allowing for greater interaction and processing of substrates. Overall, the increased surface area provided by cisternae plays a crucial role in optimizing cellular function.
Flagella. Or, are you talking about cilia?
Cilia are numerous threadlike organelles that protrude from the surface of a cell and are packed in tight rows. They are involved in cell movement and the movement of materials across the cell surface.

The word protrude is a verb (protrude, protrudes, protuding, protruded). The noun forms are protrusion and the gerund, protruding.
Mitochondria, endoplasmic reticulum, and ribosomes are organelles that play a role in maintaining the surface area to volume ratio of a cell. These organelles are involved in energy production, protein synthesis, and cellular functions that help optimize the exchange of molecules between the cell and its environment.
Flagellum or Flagella
For sand casting, it is more common to recess features into the surface rather than have them protrude. This is because recessed features are easier to achieve and maintain during the casting process, while protruding features may be less precise due to the nature of sand casting.
The long neck of the Loch Ness monster protruded above the surface of the lake.
It means "sticks out" from something. Your ears protrude from your head. The side mirrors on your car protrude from the doors.
The word protrude means to extend beyond or above a surface. There are many synonyms for this word such as: extrude, jut, jut out, bulge, swell, and distend.
True. Cilia are hair-like structures that protrude from the surface of cells and can beat or vibrate in a coordinated manner to help move substances or particles across the cell surface.
