Most root crops, as the turnip, parsnip,and carrot, do the same thing, except that they usuaUy DIFFERENT CLASSES OF P^ARM PLANTS 29 take two years instead of one to do it in. They spendone year in storing up food and the other in developingflowers and seeds. Other vegetables use a differentpart of the plant for a storehouse. The lettuce stores itssupply in a thick tuft of leaves; the cabbage in the stillmore compact bunch of leaves which we call the head;. Fig. 15. Section of cabbage. the onion in a similar bunch of leaves, developed underground, forming the bulb. In all such cases the farmer can take advantage ofthis habit which the plant has of laying up for its ownuse; if he does not care to gather a crop of seeds fromhis parsnips or carrots or cabbages, he can let the plantdo the first half of its work and then pull it up andso stock his cellar with choice vegetables for the table. The potato, perhaps our most important vegetable, isuseful for a similar reason, only in this case it does notstore food in the tuber for its own old age, but for itsoffspring.
