(N/A) The arrangement of seeds within a fruit is determined by the placentation type in the ovary of the flower.
$1$. In pea plants,the ovary has a single carpel (monocarpellary) with marginal placentation. The ovules are attached to the placenta along the ventral suture,resulting in a linear,row-like arrangement of seeds.
$2$. In tomato plants,the ovary is multicarpellary and syncarpous with axile placentation. The ovules are attached to a central axis in a multilocular ovary. As the fruit matures,the internal partitions may become less distinct,and the seeds appear scattered within the fleshy,juicy pulp of the fruit.
