What else can I help you with?
Can you give me a sentence using the word cell membrane?
A plant cell has a cell membrane and a cell wall.
What is the structure that surrounds a cell and controls what enters and leaves the cell?
The cell membrane is the structure that surrounds a cell and controls what enters and leaves the cell. It is made up of a lipid bilayer with embedded proteins that selectively allow certain molecules and ions to pass through the membrane.
What vacuole helps to give a plant cell its shape?
The vacuole in a plant cell holds water so when the vacuole is full with water, the plant cell becomes turgid (meaning swollen) so it fills up the space within the cell. This means that the cell membrane cannot droop and thus the plant cell holds its shape.
What organelle is responsible for a plants stiffness?
None. Plant cells are rigid due to the cellulose based cell wall they make just outside the cell membrane.
Do all cells have a cell membrane?
All cells need a membrane. The membrane helps with keeping in all the fluids and organelles plus it takes in and sends out important things. Plant cells and bacteria have cell walls which give an extra layer of protection.
Why is cell wall present only in plants?
rpose of cell wall is to give rigidity to plants.
Where is the cell membrane located and how is it different from a cell wall?
The cell membrane is located beneath the cell wall. The cell membrane is present in almost all types of cells whereas the cell wall is present in bacteria, fungi, algae, plant cell and is absent in protozoans and animal cells. The cell membrane is semipermeable and give support to the cytoskeleton of the cell, gives shape to the cell and helps in the formation of tissues whereas the function of the cell wall is to provide strength and rigidity to the cell, protects the cell against mechanical forces. The cell membrane is not elastic but permeable whereas the cell wall is elastic and controls turgidity. The cell membrane is found in animal cells wheres the cell wall is found in plant cells. The cell membrane is made up of lipids and proteins whereas the cell wall is made up of cellulose.
What structures do bacteria have and what are their functions?
Cell wall provides shape and give rigidity to the cell and provides a barrier to the enviroment
Does the membrane give instructions to the cell?
no the nucleus does
The bilayer arrangement of molecules in a cell membrane give the cell a?
barrier
Can you give examples of a sentence with the word membrane in it?
A cell membrane is a substance that surrounds a cell. hope this helped! :P
What are the molecules that give the cell membrane a mosaic structure?
protein molecules in the cell membrane gives the mosaic structure .
How does the cell membrane's function give the cell membrane its function?
The cell membrane regulates the entrance and exit of substances thus maintaining internal balance. It also protects the inner cell from damage and helps a cell.
Can you give me a sentence using the word cell membrane?
A plant cell has a cell membrane and a cell wall.
What keeps the shapes and protects the cell?
In an animal (and human) cell, the cell membrane gives it its shape. And in a plant cell, both a cell membrane and cell wall give it its shape and protects it
What type of cell membrane do cells have?
The cell's membrane is "selectively permeable" because the cell allows some materials to enter or leave.I'm in grade eight. This is what my Science textbook says:"Because the cell membrane allows certain substances to enter or leave, but not others, it is said to be selectively permeable."
What is the of a cell membrane in an animal cells?
if you are talking about function, it is to control what get in and out of a cell and to give the cell a shape
