The cell membrane of animal cells contains which lipid not seen in plant cells?
Cholesterol is the lipid that is found in the cell membrane of animal cells but not in plant cells. Cholesterol helps maintain the fluidity and stability of the cell membrane in animals by reducing its permeability to certain molecules.
What is a lipid that is an important component of cells only in animal cells?
Cholesterol is a lipid that is an important component of cell membranes in animal cells. It helps maintain membrane fluidity and stability, and is also a precursor for the synthesis of other important molecules like hormones.
Why does cholesterol decrease membrane fluidity in cells?
Cholesterol decreases membrane fluidity in cells because it inserts itself between the fatty acid tails of the phospholipid molecules in the cell membrane, making the membrane less flexible and more rigid.
Why does cholesterol increase membrane fluidity in cells?
Cholesterol increases membrane fluidity in cells by preventing the phospholipid molecules in the cell membrane from packing too closely together. This helps maintain the flexibility and stability of the membrane, allowing it to function properly.
What is the function of the cholesterol molecules in a cell membrane?
Cholesterol molecules help maintain the stability and fluidity of the cell membrane by preventing it from becoming too rigid or too permeable. They also play a role in regulating membrane fluidity in response to changes in temperature. Additionally, cholesterol is involved in the organization of lipid rafts, which are important for signaling and membrane protein function.
Why endocytosis found in animal only?
Endocytosis requires the fluidity of the cell membrane. Plant and prokaryotic cells have cell walls, which do not have the fluidity required to form vesicles around materials.
What is the function of a cholesterol in the cell membrane?
Cholesterol is found in the membrane. It prevents lower temperatures from inhibiting the fluidity of the membrane and prevents higher temperatures from increasing fluidity. It stabilizes the membrane. Only animal cells have cholesterol in their membranes.
What is the function of the cholesterol in a cell membranes?
Cholesterol is found in the membrane. It prevents lower temperatures from inhibiting the fluidity of the membrane and prevents higher temperatures from increasing fluidity. It stabilizes the membrane. Only animal cells have cholesterol in their membranes.

Why does endocytosis only occur in animal cells and not in plant cells?
The endocytosis only occurs in animal cells because plant cells don't have cell membranes they have cell walls. And the definition of endocytosis is " a process when a cell membrane surrounds a particle and encloses it in a vesicles to bring it to the cell." so a plant cell can't do that only animal cells can.
Why does cholesterol decrease membrane fluidity in cells?
Cholesterol decreases membrane fluidity in cells because it inserts itself between the fatty acid tails of the phospholipid molecules in the cell membrane, making the membrane less flexible and more rigid.
Why does cholesterol increase membrane fluidity in cells?
Cholesterol increases membrane fluidity in cells by preventing the phospholipid molecules in the cell membrane from packing too closely together. This helps maintain the flexibility and stability of the membrane, allowing it to function properly.
What causes these molecules in the plasma membrane of the cell lend stability to the membrane and prevent it from becoming less fluid at low tempatures?
Cholesterol molecules and protein molecules help stabilize the cell membranes. Cholesterol prevents lower temperatures from inhibiting the fluidity of the membrane and prevents higher temperatures from increasing fluidity. Cholesterol is only found in animal cells.
Why are cheek cells animal cells?
All the cells collected from an animal of which the human body is are animal.
How are animal cells from plant cells?
Animal cells are different from plant cells in that the cell wall of animal cells is not made up of cellulose.
Is centrioles in plant or animal cells?
Animal cells, not plant cells.
