The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
What else can I help you with?
Which part of the cell surrounds the cell and allows molecules in and out this cell part also has holes in it and is said to be semi-permeable?
The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
The part of the cell that is in most direct contact with the environment is the?
The cell membrane, which surrounds the cell and is responsible for which molecules are allowed to diffuse into or out of the cell and which molecules are impermeable to the membrane
What part of the cell membrane allows small molecules to pass through?
the cell membrane
Is the cell membrane a backturuim?
No, the cell membrane is not a bacterium. The cell membrane is a biological structure that surrounds the cell and regulates the movement of molecules in and out of the cell. Bacteria are single-celled microorganisms that can have a cell membrane as part of their structure.
What part of the plant cell surrounds the cell membrane?
cell wall ...
What is the name the part of the cell that surrounds the animal cell?
The thin structure that surrounds the cytoplasm of an animal cell is called as cell membrane. This is present in most plant, animal and fungi cells. It is a selectively permeable structure and allows the flow of ions and particles from the inside of the cell to the outside and vice-versa.
What part of the cell surrounds the cell membrane in plant cells?
Cell Wall
What part of the cell surrounds the cell membrane and the nucleus on an animal cell?
cell wall
Does the nucleus control the diffusion?
No, the nucleus does not control diffusion. Diffusion is a passive process that occurs based on the concentration gradient of molecules and does not require energy. It is regulated by the permeability of the cell membrane and the size and charge of the molecules involved.
The membrane surround and protect the cell?
The membrane is composed of a lipid bilayer that surrounds the cell, providing a barrier between the internal and external environment. It controls the entry and exit of molecules, allowing the cell to maintain internal conditions necessary for survival. Additionally, the membrane contains proteins that play a role in cell communication, adhesion, and transport.
Which part of the cell allows for selective permeability?
The cell membrane, composed of phospholipids and proteins, allows for selective permeability. Its structure enables it to regulate the passage of molecules in and out of the cell, ensuring that only certain substances can cross based on their size, charge, and solubility.
Which part allows or prevents substances to go into and out of the cell?
The cell membrane acts as the barrier and transport proteins present in the membrane, such as globular proteins, transport molecules across cell membranes.
