Many plants or plant parts are eaten as food. There are around 2,000 plant species which are cultivated for food, and many have several distinct cultivars.
Seeds of plants are a good source of food for animals, including humans because they contain nutrients necessary for the plant’s initial growth. In fact, the majority of food consumed by human beings are seed-based foods.
Fruits are the ripened ovaries of plants, including the seeds within. Many plants have evolved fruits that are attractive as a food source to animals, so that animals will eat the fruits and excrete the seeds some distance away.
Vegetables are a second type of plant matter that is commonly eaten as food. These include root vegetables, leaf vegetables, stem vegetables, and inflorescence vegetables. Many herbs and spices are highly-flavorful vegetables.
