Vote for the fantastic cell wall!!
The cell wall is located on the outer layer of a plant cell. The structure of a cell wall is rigid and gives the plant cell a defined figure. The cell wall encircles the plasma membrane and provides extendible strength and defence against mechanical and osmotic stress. Cell walls support the plant by sustaining the structure of its leaves, stems, and other structures because of its ability to develop turgor pressure. These walls also contain cellulose which is one of Earth's most pro-fused organic molecule. The cellulose holds together long after the plant dies. (© 2013 Nature Education)

ReplyDeletePersonally, I like the ability to have a membrane that is free and selectively permeable. Cell walls are freely permeable, meaning whatever can fit through the molecules can pass into the membrane. Take animals for example, their cells allow material in and out through free and passive diffusion and through cytosis. However, with the cell wall, its harder to allow materials to get into the cell itself for nutrient and water's sake through cytosis. Although, cell walls have holes on the sides of them that allow materials to move - one of the big defects of that is anything can get in - as long as it's soluble in water or can fit through the holes. This does include any kind of virus, or foreign object wanting to cause harm to the cell. However, since plants do have a cell membrane within it does offer an extra layer of protecting that the cell wall would normally be unable to prevent. This leaves the cell membrane with the task to sort out more than it should have to because the cell wall is more rigid than the membrane contained within it.
ReplyDeleteIt's also worth mentioning that cell membranes are what allows animals to dance, move, and run away from it's predators. Can a plant run away from it's predators? No? Who do we have to thank for this, clearly the cell wall. Perhaps that's the reason animal cells evolved to not have a cell wall, you'd have to be pretty unappealing to a predator to avoid predation. Just think about it for a little - which animal is on the top of the food chain, is it a plant or an animal? It's most definitely an animal.
Cell Walls are also one giant waste of glucose when it comes down to food - most animals do not have the proper enzymes to digest the cellulose leaving tons of glucose molecules to be left and decomposed by bacteria or animals that can digest this rough molecule.
It's also worth mentioning that you did not use a picture of a cell wall - your poster includes an image of a cell membrane.
In further addition to my post, why not vote for an organelle that works in an evolutionary manner? It's obviously important for a cell to continue my organelle, the Endoplasmic Reticulum, seeing as both plant and animal cells have it. Just look at your organelle! It's restricted to plant cells which obviously means that animals found no use for a cell wall as they evolved, but continued to constantly find use for their endoplasmic reticulum. My organelle is a universal organelle. Eukaryotic Cells have it, want it, need it. Does an animal cell need a cell wall? I rest my case.
DeleteVote Endoplasmic Reticulum!
"Eukaryotic Cells have it, want it, need it." By using this statement, you are implying that Eukaryotic Cells are intelligent sentient life forms which possess the ability to want to possess a thing or object. Cells are clearly not sentient life forms. I rest my case.

ReplyDeleteI believe that chloroplast is more important then your organelle, the cell wall. All your organelle does is act like a protection to the cell. My organelle, chloroplast, absorbs as much light as possible so the the cell can undergo photosynthesis. Without chloroplast, the plant cell could possibly die because of the lack of photosynthesis.
