Whiplike cellular extensions that move substances along the cell surface are called?
cilia
ARE many short hair like structures on the surface of a cell that help move the cell or move substances past the cell?
Both, there are two different hair like structures on cells.
How do substances move across cells in active transport?
words
What is the barrier around the that lets substances move across it?
cell surface membrane
Small network of tubes inside a cell that substances move along?
endoplasmic reticulum
What roles do cilia and flagella play on stationary cells?
They move substances along the surface of the cell.
Hairlike projections of cells that move substances along their surfaces are?
Cilia
Whiplike cellular extensions that move substances along the cell surface are called?
cilia
What projections allow the cell to move or moves substances along the surface of the cell?
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.
Cilia and flagella are used to move cells through watery environments. What role do these cells parts play on stationary cells?
they move substance along the surface of the cell
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 controls which substances can move in and out of cells?
Cell membrane controls which substances can move in and out of a cell. It is the dynamic boundary of cell

Both, there are two different hair like structures on cells.
The structure that sticks out from the cells surface and allows it to move is an?
The structure that sticks out from the cells surface and allows it to move is known as cilia. Some cells also use flagellum to move.
