Which part of a cell controls which substances can enter?
The cell membrane. It is described as semipermeable
An odor moving from one part of the room to another is osmosis or diffusion?
diffusion. Osmosis is movement across a semipermeable membrane
Infer the functions of the cell membrane All cells have a cell membrane where do you think the cell membrane of a plant cell located?
the cell membrane is the outer part of the cell wall.
What is a steroid that functions as part of the plasma membrane and as a precursor for all other steroids in the body?
Cholesterol.
What is the term for the diffusion of water across the semipermeable membrane?
The term for the diffusion of water across a semipermeable membrane is osmosis. Osmosis is when the molecules of a solvent move from a less concentrated solution to a more concentrated one. This equalizes the concentrations on each side of the member.
What is the part of the a cell that functions to maintain homeostasis relative to the cell's environment?
Cell membrane. the only part that has contact with external parts of cell. (also on yahoo answers ;)
What is a cell Membrane and it's function?
In the animal cell, the cell membrane is the outer layer of the cell, that holds the organelles and the cytoplasm inside. It also allows things to get in and to get out of the cell. The cell membrane is also an important part of the plant cell too, but it is not the outer layer. It still has the same functions, but it is inside another part of the cell called the cell wall. The cell wall is the outermost part of a plant cell ind is stiffer and thicker than the cell membrane.
What is a description of cell membrane?
It encloses the cytoplasm, and is a protective barrier that controls what goes in and out of the cell.
What is the gel like material that surrounds all parts of the cell?
The cell membrane (also called the plasma membrane or plasmalemma) is the biological membrane separating the interior of a cell from the outside environment. It is a semipermeable lipid bilayer found in all cells.The cytoplasm is the part of a cell that is enclosed within the plasma membrane. In eukaryotic cells, the cytoplasm contains organelles, such as mitochondria. The part of the cytoplasm that is not held within organelles is called the cytosol. The cytosol is a complex mixture of cytoskeleton filaments, dissolved molecules, and water that fills much of the volume of a cell. The cytosol is a gel, with a network of fibers dispersed through water.
What is prokatyotic cell part and their functions?
Prokaryotic cells do not have a nucleus or membrane-bound organelles. Instead, they contain a nucleoid region where the genetic material is located. They also have ribosomes for protein synthesis, a cell membrane for structure and transport, and a cell wall for protection.
Which part of a cell allows substances to pass through it?
The cell membrane, specifically its lipid bilayer, regulates the passage of substances into and out of the cell through a process called selective permeability. Various proteins embedded in the membrane also assist in facilitating the movement of specific molecules across the membrane.
A cell can be considered the smallest part of an?
organism that is capable of performing all the functions necessary for life. It is surrounded by a cell membrane and contains genetic material that controls its activities and reproduction.
