Vegetables are alive!
They are made of cells and need oxygen to survive, just as humans do. They interact with their environment, responding to changes in temperature, humidity and the composition of the atmosphere.
Vegetables can come from any part of the plant, from the root to the shoot tip, and everywhere in between. Where they originate on the plant affects how they are managed, and what changes occur after harvest.
This section deals with the functions and activities of the living organisms that are considered as vegetables. We discuss what a vegetable is, its structure, and how it functions.
