Answer:
Vacuoles regulate the turgidity by regulating the amount of water inside the cell. cell has excessive water: vacuole absorbs the water and then diffuses it out of the cell. cell lacks water: water from the vacuole gets passed back into the cell thereby maintaining turgidity
Binomial System
It allows for the identification and comparison of organisms based on recognised characteristics.
It allows all organisms to be named according to a globally recognised scheme.
It can show how closely related organisms are, allowing for the prediction of evolutionary links.
1. Phototropism-the growth of a plant in response to sunlight.
2. Geotropism-plant growth caused by gravity.
3. Hydrotropism-the growth of a plant towards water.
4. Thigmotropism-the growth of a plant in response to touch.
5. Tropism- plant growth caused by an external stimulus.
