Why are there so many different kinds of flowers?

1. Where did the seeds shown in part 1 of the model come from?

• Seeds come from the roots of the adult plant.
• Seeds are always present under the ground.
• Seeds come from the fruit of the adult plant.
• Seeds come from the leaves of the adult plant.

2. What would happen if you removed the bumblebee from part 3 of the model? There may be more than one correct answer. Choose all correct answers.

• The plant will not produce fruit (tomatoes) because the plant needs the bumblebee for pollination.
• The plant will not produce seeds because there will be no fruit. Without seeds there will not be future tomato plants.
• The current adult tomato plant will die because it needs the bumblebee to survive.
• The current plant will not produce flowers because the plant needs the bumblebee to grow flowers.
