Do euglenas have mouth?
yes at the top
What is the cell wall unlike the cell membrane?
Protects the nucleus with a rigid layer of cellulose
What give shapes to the cell?
A plant cell has a cell wall and a cell membrane. The cell wall is the tough outer-layer that holds the cells shape. The membrane is a layer that controls what enters the cell. Animal cells only have a semipermeable cell membrane this both holds the cell together and controls the substances that enter the cell.
What structure controls the passage of substances into and out of the cell?
cell membrane
Which cell has a cell wall and cell membrane?
Only plants, bacteria, fungi, and algae have cell walls. You are looking at an animal or protozoa cell that have no cell walls. Cell walls gives rigidity to cells.
What is the tough outer covering of a cell membrane?
Cell Wall
What is the tough outer covering that protects the cell?
I think it is the cell wall or the cell membrane
What part of a cell is stiff and getting through it is tough?
The cell wall or membrane.
What is a tough outer covering that lies just outside the cell membrane in a plant cell?
The tough outer covering that lies just outside the cell membrane in a plant cell is called the cell wall. In plant cells, it is usually made up of cellulose, hemicellulose and pectin.
Unlike the cell membrane the cell wall is A. found in all organisms B. composed of a lipid bilayer C. a flexible barrier D. made of tough fibers?
Unlike the cell membrane, the cell wall is made of tough fibres (D). The cell membrane is mainly composed of a lipid bilayer - which means it is flexible. Plant cell walls are made of cellulose, hemicellulose and pectin - which make the cell rigid.
What contains cells?
Animal cells are contained by asemipermeable cell membrane. Plant cells also have a semipermeable cell membrane, but it is surrounded by a cell wall (tough, fairly ridged and made of mostly cellulose).
What makes up the surface of a cell?
In a plant cell it is the cell wall. In an animal cell it is a cell membrane
Process by which strands of tough fibrous waterproof proteins develop within the cell membrane?
keratinization
What surrounds the individual muscle cell?
In an animal cell, the cell membrane surrounds a cell. It is like a plastic bag protecting the insides of the cell. In a plant cell, there is the same but there is also a tough cell wall like a cardboard box around the cell. Hope this helps :-)
What substance crossed the dialysis membrane?
Cells have methods other than diffusion/osmosis to move materials across the cell membrane, most of which involve membrane proteins and require the use of energy. The cell membrane also performs functions other than controlling the movement of materials into and out of the cell, and the membranes of some specialized cells have very complex functions. So we can see that the cell membrane is a very intricate and important component of the cell.
