Gas vacuole

Gas vacuole

a prokaryotic cellular organelle consisting of cylindrical vesicles around 75 x 300nm, often in clusters. The wall of the gas vacuole, which is permeable to gases but not to water, is formed from a monolayer of a single protein. Gas vacuoles are found mainly in planktonic cyanobacteria and their prime function is to make the bacterium buoyant.

Why are leaves green?

... be useless. However, most land plants that we see colored in red owe their color to anthocyan pigments. these pigments are stored in the central vacuole of a cell (and thus have absolutely nothing to do with photosynthesis) and serve the role of attracting insect and bird pollinators. I would ...

Cell Osmosis Question

... be turgid, because the fresh water would make the cell more full, and rectify any shrinkage that occurred because of the salt. The contractile vacuole is the cell organelle that could help it out, because it could expel water if the cell becomes too bloated and pops.
