What does a vesicle do in a cell?
Vesicle holds water for the cell
How are plant and animal cells similar in structure?
The similarities in the structure of a plant cell and an animal cell is that they both have a cell membrane to protect substances from coming in or out of the cell, also these to cells have a nucleus which stores the DNA within the cell. The Nucleolus which is within the nucleus that contains RNA and proteins and is involved in the production of ribosomes. These two cells contain cytoplasm which is a substance between the cell membrane and the nucleus, containing the cytosol, organelles, cytoskeleton, and various particles.
Any material coming in or out of a cell must pass through this?
cell membrane
How do molecules that are too large to cross the membrance enter into the cell?
If the large molecule won't pass through the membrane by diffusion, it might be dragged through the membrane by "endocytosis".
Why would a cell need a cell membrane?
That's like asking why do we need skin or why do milk need cups or why bear needs skin. The cell membrane protects what is inside the cell and keeps it stable. Also, the cell membranes are selectively permeable and only not allows everything to let in the cell, but going back to the first reason, if cells did not have membranes, we would look like a slime.
What type of protein is found in the cell membrane which regulates the coming and going of substances into and out of the cell?
Membrane Protein
What does the egr pressure sensor do?
It regulates the pressure coming in and out the egr valve.
How do small molecules get in the cell?
The cell membrane will allow certain small molecules to enter. The cell membrane is structured with lipids (or fats), proteins, and carbohydrates. The lipids, specifically, are phospholipids. These phospholipids are composed of two main parts, the tail and the head. The tail is hydrophobic, meaning it hates water, and the head is hydrophilic, meaning it loves water. Therefore, when a cell is put into water, these phospholipids will form a bilayer to protect the tails from water, while the heads are immersed in it. This is how the bilayer would look: iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii !!!!!!!!!!!!!!!!!!!! The dots represent the heads, and the lines represent the tails. On either side of this would be water. This phospholipid membrane functions as a selectively-permeable membrane, only allowing certain things through it. The bilayer of phospholipids will act as a barrier to larger molecules, like glucose, and charged molecules (ions). The bilayer will however allow smaller molecules like gasses (oxygen and carbon dioxide) to cross. The proteins within the cell membrane act as transport systems, and will carry smaller molecules across the membrane into the cell.

What does a regulator do on an air compressor line?
It regulates the air pressure coming out of the compressor. Usually, they are adjustable and used to lower the air pressure.
99 Yamaha blaster lights keep burning out any suggestions?
Replace the rectifier/regulator. It regulates (limits) the current coming from the magneto.
What is the out cell membrane do in a plant cell?
it is not call ed the outer membrane, its the cell wall. It does the same thing like the cell membrane, but the cell wall is much for stricter with objects coming in and out of cell, what is call, selectivly permeable
In cellular respiration what substances come from the outside?
If by respiration you mean breathing, the substance coming in is oxygen.
What is the importance of cell wall in plants?
To protect the cell contents ,and to control what substances are coming in and out of the cell.
