Celery stalks and carnation stems work well. Pollination Pollination, or transfer of pollen from a stamen to a stigma, is necessary in order for sexual reproduction to take place in seed plants. Diversity in flowers is variation in shape, size, number, color, absence, and joining together of these parts. These variations, in turn, are related to the ways in which flowers are pollinated. Dissect several flowers to see the shape and location of the four kinds of flower parts.
Geraniums are good, so are day-lilies, tulips, crocuses, and sweet peas.
Make a model of a flower, using the food items. First, cut a kiwi fruit in half and use one of the halves as a base. This is the receptacle of the flower, to which the other flower parts are attached. Dust the marshmallow with powdered sugar to represent the pollen. Then insert the lollipop stick into the center of the kiwi.
