Cell walls are made of tough cellulose fibers that provide structural support to plant cells even after they die. This helps maintain the overall architecture of the plant and allows it to stand upright. Additionally, cell walls can protect the cell from physical damage and provide defense against pathogens.

What is found in plant cell walls that account for their strength?
Cellulose. It is so tough even we humans cannot break it down.
How does the cell membrane and a vacuole work together?
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.
If a cell contains chloroplast and a cell wall what can you infer?
Containing a cell wall indicates that the cell does not belong to an animal or a protozoa. Containing chloroplast indicates that the cell is eukaryotic and conducts photosynthesis.Therefore, one could infer that the cell in question is likely a plant cell.
What chemicals are the best indicator that an unknown substance is a plant?
Cellulose is an extremely good indicator. Plant cells have cell walls, which are mostly cellulose. Animal cells do not have cell walls.Another one is chlorophyll ... though that's not quite as good, since only some plants produce chlorophyll, and even they may not produce it in all parts of the plant (for example, it wouldn't usually be found in the roots).
If a plant cell is put into a concentrated sugar solution what will happen?
Those animal cells placed in pure water will swell but plant cells are restricted by their cells walls. If place in a solution high in sugar (or even salt), both cells will shrink in a process called crenation (shriveling).
Why cell wall is necessary in animal cell?
Cell walls are only found in Plant Cells. So they are not even there to do anything
What are cell walls made up of?
Cell walls are primarily composed of cellulose, a complex carbohydrate, in plants. In bacteria, cell walls are made of peptidoglycan. Fungi have cell walls made of chitin. These cell wall components provide structure, support, and protection for the cells.
What are walls made up of?
If you are referring to plant cell walls, then they are made up of primarily cellulose and carbohydrates. Even though carbohydrates do make up cell walls in plants, cellulose (a polymer of glucose {consists of many glucose molecules}) is the primary structural component of a plant cell wall.
Compare the primary and secondary cell walls?
the primary wall can still grow with the cell, while once the secondary wall is created the cell can no longer grow. Even after the cell dies, the secondary wall will remain.
Does Fungus have cell walls?
Yes, fungi have cell walls. These cell walls are composed of chitin, a complex carbohydrate that provides structural support and protection for the fungal cells.
What is found in plant cell walls that account for their strength?
Cellulose. It is so tough even we humans cannot break it down.
How do cell walls help plants survive on land?
Cell walls provide structural support and protection to plant cells, allowing them to stand upright against gravity and withstand various environmental stresses. Cell walls also help regulate water balance, preventing cells from bursting or collapsing in fluctuating conditions. Additionally, cell walls contribute to plant defense mechanisms against pathogens and herbivores.
When a plant needs water it will wilt but the tissues themselves remain rigid explain why?
When a plant doesn't receive enough water, there is a loss of turgor pressure within the plant cells, causing the plant to wilt. However, the cell walls of the plant remain rigid even when wilting due to the presence of structural components like cellulose. So, while the plant may appear wilted, the cell walls provide some structural support, maintaining the plant's overall shape.
Why cant an animal cell have a cell wall?
Animal cells have a cell membrane, plant cells have a cell wall and a cell membrane. Animals (espeacially simple organisms) are motile, having a cell wall restricts movement as cell walls are rigid structures. Imagine if a human cells were to have cell walls, the rigidity of the structure would slow or even impede movement - basically we'd end up like plants pretty much stationary.

Are plant cell walls mostly protein?
Yes, plant cell contains proteins. Even the plant cell wall is made up of protein. All living beings contain a cell wall which is mostly made up of protein. And also plant cells prepare cell proteins also which are used for synthesis of many enzymes, amino acids, and many substances. Main source of protein in plant cell is nitrogen. Palisade cells help in synthesis of carbohydrates which inturn is prepared into fats, proteins, glucose. Thus plant cells contain proteins.
