Hydrophobic
Hydrophobic molecules are water hating. They repel or fail to mix with water. Also called nonpolar molecules, examples include alkanes, oils, fats, and greasy substances. Hydrophobic materials can be used to help clean up oil spills.
Modified Leaf of a Plant
The modified leaf of a plant is a n adaptation on a plant meant for its own survival due to environmental stress. A leaf performing functions other than transpiration and photosynthesis is an example. Other things include structure changes like color and spikes. An onion is special in the case that its center contains a modified root but most of what we eat on the outside are modified underground leaves that store energy for the plant to survive during the winter.
