Answer:Seed shape is an important trait in plant identification and classification. In addition it has agronomic importance because it reflects genetic, physiological, and ecological components and affects yield, quality, and market price. Seed shape is determined by a variety of indexes (circularity, roundness, and index).
If they didn't differentiate then the stem cells would stay the same type and if it somehow kept multiplying then they would just be a massive blob with no actual form or way of functioning.
