While cell membranes might be around every cell, cell walls made of cellulose are only found around plant cells. Cell wallsare made of specialized sugars called cellulose. Cellulose provides a protected framework for a plant cell to survive. It's like taking a water balloon and putting it in a cardboard box. The balloon is protected from the outside world. Cellulose is called a structural carbohydrate (complex sugar) because it is used in protection and support.
Cell walls also help a plant keep its shape. While they do protect the cells, cell walls and cellulose also allow plants to grow to great heights. While you have a skeleton to hold you up, a 100-foot tall redwood tree does not. It uses the strong cell walls to maintain its shape. For smaller plants, cell walls are slightly elastic. Wind can push them over and then they bounce back. Big redwoods need strength in high winds and sway very little (except at the top).
Another Hole in the WallA cell wall is not a fortress around the delicate plant cell. There are small holes in the wall that let nutrients, waste, and ions pass through. Those holes are called plasmodesmata. These holes have a problem: water can also be lost. But even when the plant cell loses water, the basic shape is maintained by the cell walls. So if a plant is drooping because it needs water, it can recover when water is added. It will look just the same as when it started.
More Than Walls in PlantsYou may hear about cell walls in other areas of Biology. Bacteria also have a structure called a cell wall. Fungi and some ptotozoa also have cell walls. They are not the same. Only plant cell walls are made out of cellulose. The other walls might be made from proteins or a substance called chitin. They all serve the same purpose of protecting and maintaining structure, but they are very different molecules.

What are organelles that play a major role in the cell division?
The cell membrane. But if the cell is a plant cell, the cell membrane and cell wall work together to accomplish this task.
How do the endoplasmic reticulum and cell membrane work together?
The ER, does not only play a major role in creating protiens, but also helps transport proitiens to the cell membrane. Here they can then leave the cell if needed.
Does a root hair cell have vacuole?
it allows waste products to leave the cell and allows healthy products to enter the cell! :) have fun with work! :D
What cell organelle makes turgor pressure in a plant cell possible describe the role of this oranelle in this process?
The nucleus is the control center of a cell as such it is the most important part of the cell. The control arises from the genetic information stored in the nucleus. Genes are made of the nucleic acid DNA. Hundreds of genes are linked together into enormous molecules called chromosomes (chromatin). Genes can be switched on or off and are indirectly responsible for making proteins which do the work of the cell.
What method of cell transport is at work when you are dehydrated?
the cell membrane
What keeps the cell from passing out of the cell?
the cell membrane controls it. if it is a plant, both cell membrane and wall work together.
What organelles work as storage tanks for the cell?
the vacuole
What is the relationship between vacuole and organelles?
yes there are many relationships between organelles in cells. the work together to function the cell.
What are organelles that play a major role in the cell division?
The cell membrane. But if the cell is a plant cell, the cell membrane and cell wall work together to accomplish this task.
What cells work together?
ribosome and vacuole
How do the endoplasmic reticulum and cell membrane work together?
The ER, does not only play a major role in creating protiens, but also helps transport proitiens to the cell membrane. Here they can then leave the cell if needed.
How does a cell membrane work for the cell?
It protects the cell.
Does a root hair cell have vacuole?
it allows waste products to leave the cell and allows healthy products to enter the cell! :) have fun with work! :D
What is a Work of cell membrane?
To let water and minerals in and out of the cell.

The cell membrane contains lipid molecules that?
The cell membrane contains lipid molecules that provide a barrier to the free movement of ions into and out of the cell.
What method of cell transport is at work when you are dehydrated?
the cell membrane
