Students can begin this investigation with the model disassembled, and “build” the flower as they learn about the arrangement of floral components and reproductive functions. One anther is sectioned open to reveal the pollen grains within. Adhering to the stigma are six pollen grains, one of which has generated a pollen tube that has entered the ovary. Floral structures are number-coded for identification in the key that accompanies the model. Size 17”L x 14”W x 10”H.
