Turgor Pressure

The tissues of plants, bacteria, fungi, and some protists are kept erect by water pressure within their cells, called turgor pressure

The cell plasma membranes of plants are differentially permeable, so that while water molecules can enter and exit, the larger salt molecules inside cannot escape: since turgor pressure is maintained by osmosis (the diffusion of solute molecules from an area of higher concentration to an area of lower concentration) the solute concentration within the cell affects water pressure to build up in the cell membrane, giving the plant a rigid structure.

This is why plants wilt when they have insufficient water: their cellular membranes are essentially deflated, which normally provide support to the cell walls.

ever since I saw a video of craig mccracken at comic con and saying how he was originally going to have Eduardo sound really beautiful, this has been sitting in my head for the past couple of days and I felt the need to share this with the world. 

It is 2am down here please spare me

  • Red
  • Known for saying “okay”
  • Beautiful smile
  • Name that references death (Flowers Wilt when they’re dying; Mt. Megiddo is a mountain believed to be the location of the Armageddon, and her handle is apocalypseArisen)
  • Good friends with an under-confident guy with bull horns (Eduardo; Tavros)
  • Also friends with an eccentric character who is associated with eggs (Coco; Terezi)
  • Not appreciated enough for how helpful and friendly they are
  • Literally the same character, how did Andrew Hussie get away with this.
