You Are on an Expedition into a Tropical Rainforest

You are on an expedition into a tropical rainforest. You notice a tall plant with large, long, conical purple flowers that produce nectar. When you ask your guide about the plant, she pulls out a large pink fruit from her bag and explains that it is from the plant with the purple flowers. After tasting the fruit, you decide to bring the plant back home and cultivate it. You are successful in producing a crop of the pink fruit. You save some of the seeds to plant the following year. When the next growing season starts, you plant the seeds in the same greenhouse. To your surprise, no plants grow. What is a possible reason for this?

A) The seeds do not germinate because the flowers were not pollinated by butterflies.
B) The plants will not grow in close proximity to each other.
C) The seeds must pass through the digestive tract of a seed dispersal organism to germinate.
D) Because the plants self-pollinate, the endosperm does not develop properly, and thus the seeds do not germinate.
