Distingush between cell wall and cell membrane?
Cell wall: made from cellulose, very strong, provides structure and strength for the cell, mainly found in plant cells Cell Membrane: made from cytoplasm, found in all cells and some organelles, partially permeable to allow substances to travel in and out of cell, site of active transport and contains carrier proteins and receptors to attach chemicals
What a stiff layer of nonliving material that surrounds a plant cell?
Cell Wall
What structure around the outside of the plant cell keeps them from rupturing from too much water?
Cell Wall
What is the rigid outermost layer of the plant cell?
The cell wall surrounds plant cells.
What is the outside of a plant called?
the cell wall, or it could also be the cell membrane, the cell wall is outside the cell membrane
Is a cell wall permeable partially permeable or impermeable?
the cell wall is fully permeable
Is the cell wall fully or partially permeable?
yes,it has to be
Is a cell membrane permeable impermeable or partially permeable?
Plasma membranes are selectively permeable.
Cell wall cell membran and tonoplast which boundry is partially permeable?
yes, it has to be (semi-permeable, to let the cell membrane conrol the process of osmosis(e.g water will go in, but not sugar)
Why is the cell membrane still attached to the cell wall at some point when the cell is plasmolysed?
Cellulose microfibrils extending from strands of the Hechtian reticulum and entwining into the cell wall matrix act as anchors for the plasma membrane as it moves away from the wall during plasmolysis.
Is the cell wall and the cell membrane the same thing?
No. The cell wall is made of a stiff material which protects the cell and keeps its shape regular. It is usually composed of a complex carbohydrate. The cell membrane is a thin partially-permeable layer of phospholipids surrounding the cytoplasm which controls the movement of substances in and out of the cell. It does not allow bigger molecules such as the other structures of the cell to move out of the cell except through special channel proteins. All cells have a cell membrane, but not all cells have a cell wall.
What protects the plants cell?
cell wall
Where is the cell wall located in an animal?
There is no cell wall in a animal cell but there is a cell wall in the plant cell.
What is a outer supportive structure of a plant cell?
The cell wall is the outer supportive structure of a plant cell. It provides rigidity and support to the cell, helping the plant maintain its shape and structure. The cell wall is made up of cellulose, a complex carbohydrate that gives strength to the cell.
What does a plant cell wall and animal cell wall have in common?
An animal cell does not have a cell wall.
What is cellouse cell wall?
Cell wall made out of cellulose is the cell wall of a plant. A fungi has a cell wall composed of chitin and a bacteria has a cell wall composed of glycoprotein.
What other uses of the cell membrane?
The cell membrane is partially permeable, to allow nutrients like glucose and oxygen to enter the cell, and for waste products (eg. CO2 and urea) to exit the cell. It does not hold the cell together; this is carried out in plant cells by a cellulose cells wall.
