Answer 1

SNAPDRAGON

Is it complete or incomplete?

• Snapdragon is complete because it has all the four essential basic parts of a flower i.e. calyx, corolla, androecium, and gynoecium.

What type of symmetry does it exhibit?

• The ovary is superior in snapdragon because all other parts of a flower i.e. sepals, petals and stamens are below it.

Is the flower hypogynous, perigynous, or epigynous?

• the flower is hypogynous because the ovary is superior.

How many locules (cavities) are in the ovary?

• there are two locules present in the ovary of snapdragon i.e. it is bilocular.

What is the likely number of carpels forming the ovary?

• there are two carpels forming the ovary.

What are the numerous white, oval structures found in the locules?

• Ovules
