Do all sunflower seeds have the same length and thickness why do you think the seeds different in so many ways?

No, not all sunflower seeds have the same length and thickness; they can vary based on factors like the specific sunflower variety, growing conditions, and genetic traits. Different seed sizes and shapes can influence germination rates, growth patterns, and resilience to pests. Additionally, variations can be an evolutionary adaptation to optimize survival and reproduction in diverse environments. These differences ultimately contribute to the overall diversity within sunflower species.
