When Mom Told You to Eat your Vegetables.she lied!The following is NOT a vegetable

SoWhat is a Vegetable?Generally speaking, a vegetable is any plant part NOT involved in sexual reproduction. Usually a vegetable is a plants roots, shoots, or stems.and will never be a fruit (contains seeds) or a flower (contains a plants reproductive organs)

Roots, Shoots, Stems, and Leaves

RootsCarrots and parsnips are underground roots that become swollen as they accumulate stored photosynthate, and are called tap roots. carrotsparsnips

RootsThe sweet potato is a swollen root, distinguished from the potato by the lack of "eyes" or lateral buds.sweet potato

StemsOnions and garlic are referred to as bulbs, modified stems in which the primary storage tissue is expanded leaf basesoniongarlic

StemsGinger is a branched, underground compressed stem referred to botanically as a rhizome. ginger

StemsA potato is an unexpanded, underground stem that is called a tuber. The dimples on the surface of the potato, the "eyes", are actually lateral buds.potato

StemsA vertical, unexpanded, underground stem is called a corm. A corm is solid inside (unlike a bulb) and doesnt usually have nodes all over like a tuber. There is often a papery covering composed of leaf bases. Examples: water chestnut, taro.potato

Types of Leaves

LeavesWhen we eat lettuce, we eat the leaves. There is considerable variation among the types of lettuce. Some types form a tight head, while others are harvested as "leaf" types. Color varies from green-yellow, to red to purplish.

LeavesThe cabbage head is an unexpanded stem surrounded by overlapping, fully expanded leaves. The leaves are usually shredded or cut away from the stem, and the stem itself is rarely eaten.cabbage

LeavesThe edible portion of celery is the petiole, the small stalk attaching the leaf blade to the stem. The whole, unexpanded celery shoot may be eaten as well, called hearts of celery.celery

How to be Successful in this Lab FACT: Lab practicals and quizzes will be based on your ability to identify a given vegetable, fruit, flower, etcso learn them and be able to visually recognize them!

Use the prop resources available to you during lab by taking time to familiarize yourself with each specimen - DO NOT divide and conquer!

Bring your lab packet with you to each lab.

Make flashcards and study/learn them by grouping them and making multiple connections - place of origin, family, part of the plant, etc.

Prop CardsYou will meet a lot of plants this semester, presented as fresh or dry products or packaged props. Each will come with a prop card carrying the information you need to know. Learn how to interpret the material on each card.
