Think of a drop of oil in a bowl of water. What happens when it is pierced with a toothpick?
The plasma membrane is a series of phospholipid molecules. This molecule is amphipathic. The lipid part of the molecule hates water, hydrophobic. The phosphor part of the molecule loves water hydrophilic. These molecules orient themselves so that part of the molecule is facing what it loves. The hydrophobic lipid part remains together with phosphor heads sticking out on each side. This keeps the hydrophobic tails away from water and the hydrophilic heads next to the water. This structure then forms a sphere around the cell with a watery substance inside and outside the cell.
This membrane further contains substances, proteins, cholesterol and even carbohydrates.
What else can I help you with?
What is the thin flexible membrane around all cells?
the cell membrane is as flexible barrier outside of the cell.
What is the structure and appearance of a cell membrane?
The cell membrane is a thin, flexible barrier that surrounds the cell. It is made up of a double layer of phospholipid molecules with proteins embedded throughout. This structure gives the cell membrane its fluidity and allows it to regulate the passage of substances in and out of the cell. The cell membrane also contains cholesterol molecules that help maintain its stability and integrity. Overall, the cell membrane has a semi-permeable nature, meaning it selectively allows certain substances to pass through while blocking others.
What does the plasma membrane look like in a cell?
The plasma membrane in a cell is a thin, flexible barrier made up of lipids and proteins. It has a phospholipid bilayer structure, with proteins embedded within it. This membrane surrounds the cell and controls the movement of substances in and out of the cell.
Why can the cell membrane not be a completely solid structure?
A membrane has to be flexible to let things into a cell. A flexible membrane gives the cell form flexibility and lets it perform endocytosis and phagocytosis. Besides, the membrane asorbs nutrients and water easier.
What is the flexible outer layer of the cell called?
The cell membrane is flexible and the cell wall is stiff.
What is a flexible structure that holds cell together?
the cell membrane
What is the name of the flexible structure that holds cell together?
Cell membrane.
Is the cell membrane a fixed structure?
The cell membrane is an asymmetric phospholipid bilayer and as such it is flexible like an elastic sheet.
What organelle gives the cell its shape and provides protection and is not found in an animal cell?
The cell wall is the organelle that gives plant cells their shape and provides protection by acting as an extra layer outside the cell membrane. Animal cells do not have cell walls; instead, they have a flexible cell membrane that gives them shape and structure.
Flexible structure that holds cells together?
The cell membrane holds a cell together.
What are the molecules that give the cell membrane a mosaic structure?
protein molecules in the cell membrane gives the mosaic structure .
What is thin flexible structure that surrounds an animal cell and is found below the cell wall in a plant cell?
the cell membrane
What structure surrounds the cell membrane in plants gives the cell support?
Cell Wall
What structure surrounds the cell membrane (in plants) and gives the cell support?
Cell Wall

Which of the following is found in plant cells to give it structure but not found in animals?
Cell walls made of cellulose are found in plant cells to provide structure and support. Animal cells do not have cell walls; instead, they have a flexible cell membrane that gives them shape.
