What else can I help you with?
Through which organelle do substances enter or leave a cell?
Substances pass through the plasma membrane, although ot is not technically an organelle.
What must a substance pass through to enter or leave a cell?
A substance must pass through the cell membrane in order to enter or leave a cell. This process can occur through various methods such as simple diffusion, facilitated diffusion, active transport, or endocytosis/exocytosis. The cell membrane acts as a barrier that selectively allows certain substances to pass through while blocking others.
The flexible outer boundary of the cell through which substances enter and exit is called?
Cell membrane
What does the cell membrane do to avoid hings going inside the cell?
Cell membrane is a Selectively Permeable Membrane so it does not allow all the substances to pass through it.It controls the movement of substances in and out of the substances.Unlike a cell membrane,the cell wall has large holes in it allowing the water and dissolved minerals to pass through hence cell wall is known as Freely Permeable 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 is the substances that passes through a cell?
cell membrane
What type of molecules can easily go through your cell membrane or are permeable to the cell membrane?
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.

The flexible outer boundary of the cell through which substances enter and exit is called?
Cell membrane
What part of the animal cell allows things to go in and out of the cell?
The cell membrane, which is a lipid bilayer, controls the movement of substances in and out of the cell through processes like diffusion, osmosis, and active transport. It acts as a selective barrier, allowing some substances to pass through while blocking others.
How are diffusion and facilitated diffusion similar?
Substances enter a cell through the cell membrane
What only allows certain substances in and out of a cell?
The permeability of the cell membrane controls which substances may pass in or out of the cell.
What is a type of protein found in the cell membrane which regulates the coming and going of substances into or out of the cell?
Channel proteins are a type of protein found in the cell membrane that regulate the passage of specific ions or molecules into or out of the cell. These proteins form channels or pores that allow substances to pass through the membrane, controlling the movement of substances across the cell membrane.
What specific substances can pass through a cell membrane by diffusion?
Oxygen
How does the composition of the cell membrane help regulate the movement of substances into and out of the cell?
The cell membrane is composed of a phospholipid bilayer that is selectively permeable, allowing only certain substances to pass through. The presence of proteins, such as channels and carriers, also help regulate the movement of specific molecules across the membrane. Additionally, the membrane's fluidity and structure play a role in facilitating or hindering the diffusion of substances.
What is the part of the cell that materials pass through?
Materials pass through the cell membrane, which acts as a barrier between the cell's interior and the external environment. The cell membrane is selectively permeable, allowing certain substances to pass through while blocking others.
