Projections that allow the cell to move or to move substances along the surface of the cell are called cilia and flagella. Flagella is a single long hair that allows the cell to swim. Cilia are several projections used for movement across the cell surface.

What travels along a surface separating two media?
a surface wave
What is to move smoothly along a surface?
slide
What is the direction in which the surface tension acts when the liquid is at rest?
it acts along the surface of liquid
What instrument measures the force of an object pulled along a surface?
A force-meter measures the force of an object pulled along a surface.
Why is the ray passing through centre of curvature reflects along the same path?
Because a ray that passes through the center of curvature falls perpendicular to the surface (along a normal to the surface), hence it is reflected along the same path.
Hairlike projections of cells that move substances along their surfaces are?
Cilia
What is the cell's hairlike structure that helps with locomotion?
Hairlike projections that aid in the movement of substances along a cell's surface are called cilia
What is the Surface area of small intestines?
Along the small intestine are finger-like projections called villi which increase the surface area to allow the removal of fats/lipids by the lacteals of the lymphatic system. About equal to a tennis court.
Whiplike cellular extensions that move substances along the cell surface are called?
cilia
What cellular organelle is a projection that moves substances along the surface of a cell?
cilia
What roles do cilia and flagella play on stationary cells?
They move substances along the surface of the cell.
Move substances along the surface of cells?
Flagella, pseudopodia. cilia
What organelle moves substances across the cell in one direction?
The plasma membrane surrounding animal cells is where the exchange of substances inside and outside of cells takes place. Some substances need to move from the extracellular fluid outside cells to the inside of the cell, and some substances need to move from the inside of the cell to the extracellular fluid.Some of the proteins that are stuck in the plasma membrane help to form openings (channels) in the membrane. Through these channels, some substances such as hormones or ions are allowed to pass through. They either are "recognized" by a receptor (a protein molecule) within the cell membrane, or they attach to a carrier molecule, which is allowed through the channels. Because the plasma membrane is choosy about what substances can pass through it, it is said to be selectively permeable.
What are the finger like projections in the small intestine that act to increase the surface for absorption?
finger like projections in small intestine are called villi to increase surface area for absorption of food in small intestine.
Why are the villi shaped the way they are?
This is to allow a larger surface area (for absorption etc) and to allow them to 'wave' unwanted products along (phloem in the oesophagus)
Why does intestinal tissue has so many projections?
isn't the many folds in the the intestines along with the villi and microvilli all there to increase the surface area of the intestines? which would increase the absorption of nutrients into the bloodstream or lymph vessels?
What are the function of epithelial cells?
The cilia on their surface trap dust and microbes, then pass the trapped substances along with mucus to the throat, where they can then be swallowed. This then protects the lungs.
