Most molecules can move in and out of a cell, but different molecules have different methods of getting in-
Small Non-Polar molecules can diffuse across the lipid bilayer
Medium sized molecules of any kind require a specific protein channel
HUGE MOLECULES require a process called endo and exocytosis

When substances pass through diffusion they move from areas of their what to areas of their what?
it moves from high to low concentration
What characteristics of cell membranes may explain why fat-soluble substances such as chloroform and ether rapidly affect cells?
The fact that cell membranes are semi-permiable creates openings for the substances to enter.

Which material move through the cell in diffusion?
All the imports and exports of cell moves through plasma membrane by diffusion. Which includes proteins, water, nutrients and the products of the cell. The material in excess amount in or out of the call moves in or out of the by diffusion.
What are The basic substances in a cell?
proteins, nucleic acids, sugar, and carbohydrates !
What moves substances into and out of the cell in facilitated diffusion?
coffee
What Controls what moves into cells?
The Cell Membrane is usually attributed with controling which substances can move in and out of the cell.
Controls what moves into cells?
Cell membranes control what moves into cells by selectively allowing certain substances to pass through while blocking others. This selectivity is maintained through various processes such as diffusion, facilitated diffusion, and active transport. Additionally, cell membranes contain specific transport proteins and channels that help regulate the movement of molecules in and out of the cell.
What organelle transport things around the cell?
The endoplasmic reticulum moves substances through the cell within channels made of membranes. The cytoplasm also moves substances and organelles through cytoplasmic streaming
What cellular organelle is a projection that moves substances along the surface of a cell?
cilia
What book transport process moves materials into cells?
The process that moves materials into cells is called endocytosis. During endocytosis, the cell membrane surrounds particles or substances outside the cell, forming a vesicle. The vesicle then fuses with the cell membrane and releases its contents into the cell.
What is an extensive system of internal membranes that moves proteins and other substances trough the cell?
Endoplasmic Reticullum(E.R)
What moves things through the cell membrane?
If you mean through the cells itself, that would be the endoplasmic reticulum but if you mean substances from the outside of the cell into the cell that is done by protein channels.
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.
What Controls what moves in and out of the cell?
Cell membrane
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 does concentration gradient have to do with diffusion of substances across the cell membrane?
concentration gradient moves from high to low until equilibrium is reached.
