Water’s small size is important for plants as it is able to diffuse by osmosis into plant cells which creates turgor as the vacuole swells pressing against the cell wall. This pressure helps plants stand up straight and not wilt causing death
As water is lost by transpiration from the leaves tension is created in the mesophyll cells causing the water droplets to move up the stem to the leaves against gravity. This is called capillary action and provides leaves with water for photosynthesis. This is a very important process for the existence …show more content…
This is because the anions are attracted to the positive hydrogen and the cations are attracted to the negative oxygen causing the compound to dissociate. It is therefore a large component of blood plasma as it is very useful for transporting salts around the body.
This means that water below 3OC, which is less dense, rises to the surface and solidifies. This ice layer insulates the water preventing it from freezing
Below this temperature, it is harder to form hydrogen bonds and so there is more space between molecules
In the Arctic, water provides habitats for marine life, like whales, whilst polar bears live on the ice. The abnormal density of water allows both states to simultaneously exist, as water is densest at 4OC because the molecules are arranged in a tetrahedral pattern held together by hydrogen bonding
The transparency of water allows light to reach coral, which contain photosynthetic algae, 20m deep. The algae photosynthesise providing glucose for the coral polyp, which is important for habitats for other aquatic life. The low boiling point means that mammals, like dogs, produce sweat to cool themselves down to prevent cells overheating causing proteins to
