WHICH SEED WOULD GROW FASTER A LITTLE SEED OR A BIG seed
If it was properly fertilized and formed, yes.
A marigold typically takes about 8-10 weeks to grow from a seed to full maturity, where it will bloom and reach its full size.
There are many varieties of sunflower, from 12" high to 12 feet high at maturity. They all start from seed in the spring, reaching maturity, blooming and going to seed in the fall. While roses can add to their size by quite a bit during one season - some canes can grow two or three feet - I would have to say that a sunflower grows faster.
If you put a cut stem in the soil, it is unlikely the sunflower would grow. It would need to grow from seed.
