Not necessarily: consider striped toothpaste.
Tooth paste is a homogeneous mixture.
I consider this product as a homogeneous paste.
If the toothpaste is striped, it is a heterogeneous mixture, because more than 1 substance is visible in the mixture. If the toothpaste is a gel, it is also heterogeneous. Plain white toothpaste is a homogeneous mixture because only 1 substance is visible :)
Poppy seeds themselves are not a homogeneous mixture; they are individual seeds that can be considered a heterogeneous mixture when combined with other ingredients. However, if you grind or process poppy seeds into a paste, that mixture could be considered homogeneous, as the individual components would be evenly distributed. In their natural form, though, each seed retains its distinct characteristics.
