}. That won't compile. You can only use override when the method is virtual in the base class. And once it's virtual in the base class it's virtual in the n-th child too. So you don't have to re-specify virtual when you override a method.
Various vascular tissues in the root allow for transportation of water and nutrients to the rest of theplant.Plant cells have a cell wall to provide support, a large vacuole for storage of minerals, food, andchloroplasts where photosynthesis takes place.
Energy from sunlight, water absorbed by the roots, and carbon dioxide from the atmosphere produce glucose and oxygen by photosynthesis. Photosynthesis is the process by which plants and other things make food. It is a chemical process that uses sunlight to turn carbon dioxide into sugars the cell can use as energy. As well as plants, many kinds of algae, protists and bacteria use it to get food. Photosynthesis is very important for life on Earth.
