Answer: E, Plants disseminate fruit through fruit. In addition to a way to spread seeds, fruit also serves to protect seeds from environmental factors.

Key Takeaway: Most people would agree that fruit is delicious, and it is delicious for a reason. As fruit is typically sweet, it is purposely designed to be appealing to animals. Animals eat fruit, but the seeds are not digested along with the fleshy part of the fruit as the seed is protected by a coat that is resistant to digestive enzymes. When the animal defecates, seeds are released along with fresh “fertilizer”, a process known as seed dispersal. The seed is now in an environment supportive of growth, and the plant has spread as a result.
