Final answer:
The arrangement of seeds inside fruits is determined by their mode of seed dispersal, with different fruits having different adaptations for dispersal by wind or animals.
Step-by-step explanation:
Fruits possess different arrangements of seeds inside their bulk depending on their mode of seed dispersal. The variety of shapes and characteristics of fruits reflect how they are dispersed. Some fruits are wind-dispersed and have lightweight structures or wing-like appendages to be carried by the wind. Others are dispersed by animals and have features like attractive colors, scents, or burrs and hooks to cling to fur.
