Flower Dissection

Which table correctly identifies the function of each structure or group of structures in the reproduction of the plant?

• X = Pollen Production

  Y = Pollen Transfer

  Z = Production of Eggs

• X = Attraction of Pollinators

  Y = Production of Male Sex Cells

  Z = Egg Production and Embryo Development

• X = Protection of Embryo

  Y = Supply Nourishment to Embryo

  Z = Place of Embryonic Development

• X = Photosynthesis

  Y = Production of Cells that Protect Internal Organs

  Z = Production of Eggs and Sperm

Which of the following best describes the interaction that occurs between a plant’s reproductive parts during self-fertilization?

• Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches the filament, where the sperm fertilizes the egg.

• Pollen moves from the ovule up through the style and is released from the stigma. The pollen is transferred to the anther, where the sperm fertilizes the egg.

• Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary, where the sperm fertilizes the egg.

• Pollen is released from the stigma and is transferred to the anther. A pollen tube grows down from the anther through the filament and fuses with the ovule, where the sperm fertilizes the egg.
