cell wall

we are the best organelle out there, just protecting and serving the luckiest of cells

[cell wall @cellwall2018hs]

@membrabe too bad plant cells need us because you can’t handle turgor pressure in plant cells #gootapbio #organellevote2018

[cell wall @cellwall2018hs]

transport proteins for the win #gootapbio #organellevote2018

[cell wall @cellwall2018hs]

our pores allow communication signals and molecules to pass between cells so everyone knows what's up #gootapbio #organellevote2018

[cell wall @cellwall2018hs]

we play an important role in cellular communication because of our plasmodesmata which are small channels or pores between the cell walls #gootapbio #organellevote2018

[cell wall @cellwall2018hs]

the secondary cell was is usually made of hemicellulose and cellulose. but, some that may contain lignin, which is responsible for strengthening the cell wall and also for the conductivity of water in what is known as plant vascular tissue #gootapbio #cellvote2018

[cell wall @cellwall2018hs]

we are important in poplastic transport, which is transport through the layer outside the plasma membrane to move gases such as carbon dioxide, or plant hormones and pheromones #gootapbio #organellevote2018

[cell wall @cellwall2018hs]

we're designed to completely coat the cell membrane. you're welcome @membrabe #gootapbio #organellevote2018

[cell wall @cellwall2018hs]

previously it was thought that all cells had shared walls but the notion was completely changed when in 1804, J. H. F. Link and Karl Rudolphi went on to prove that every cell has its own cell wall #gootapbio #organellevote2018

[cell wall @cellwall2018hs]

over-expansion prevention is achieved with the help of polysaccharides, structural proteins and cellulose fibers #gootapbio #organellevote2018

Robert Hooke was the first person to observe the cell wall in 1665 when he referred to it as "wall"- i guess @realDonaldTrump isn't so original

[cell wall @cellwall2018hs]

some cells have a secondary cell wall which helps provide support because of its rigid structure #ridgesforthewin 😉🤭🤫😏 #gootapbio #organellevote2018

[cell wall @cellwall2018hs]

we control cell growth direction #gootapbio #organellevote2018

[cell wall @cellwall2018hs]

regulation of cell growth is yet another important function of cell wall- it's responsible for sending cell division and cell growth signals to cells so that they can enter into the cell cycle #gootapbio #organellevote2018

[cell wall @cellwall2018hs]

a cell wall is naturally porous, selecting on some to pass through #gootapbio #organellevote2018

[cell wall @cellwall2018hs]

we regulate the entry of various material into the cell #gootapbio #organellevote2018

[cell wall @cellwall2018hs]

we are responsible for carbohydrate storage which is essential to cell growth #gootapbio #organellevote2018

[cell wall @cellwall2018hs]

in plants the cell wall is 0.2 µm thick, or should we say thiccc #gootapbio #organellevote2018

[cell wall @cellwall2018hs]

turgor pressure keeps the plants erect; a cell membrane @membrabe can't withstand the pressure and would burst, but the cell wall can do it #organellevote2018 #gootapbio

[cell wall @cellwall2018hs]

one of our most important functions is to work as a skeleton and provide the framework that can prevent the plant cells from over-expansion- so there's room for everyone #organellevote2018 #gootapbio

[cell wall @cellwall2018hs]

our primary layer of cell walls is composed of cellulose microfibrils- pretty sweet #organellevote2018 #gootapbio
