There are also

edible plant parts that don't

fit into the system very well: herbs,

spices, and nuts form their own

groups. And mushrooms also can't

be grouped with anything else.

Cress is a kind of herb, while beans are

a vegetable, and an apple is a fruit. That

much is obvious! But an avocado — is

that a fruit or a vegetable? And what

exactly is the difference?

The answer is not so simple. Of course,

it depends on the person providing it. A

cook would say that all fruits are sweet or

tart, and can be eaten without having to

be prepared.

Vegetables have to be seasoned or

cooked in order to taste good — so, for

example, a squash or an avocado. Of the

legumes, we usually use just the seeds in

the kitchen (beans, peas, and lentils). In

addition, other plant parts such as roots

or leaves are grouped together with veg-

etables if they have to be seasoned or

cooked — for example, spinach (leaves)

or carrots and radishes (roots).

A botanist (the name given to plant

researchers) would draw the line some-

what differently. Botanically, the most

important thing is which part of the plant is

used. So a botanist would put fruits

like apples, cherries, and straw-

berries in the same pot with

tomatoes and squash. And

vegetables would be divided

between leafy vegetables

and root vegetables.
