Watermelon flower

I'm examining a Watermelon plant that grows on its own from seeds that were accidentally wasted or maybe the seeds were brought in by birds.

I took the initiative to take care of it by adding manure and putting some dry wood branches so that the watermelon plants could propagate.

Watermelon plants have yellow flowers and have 5 petals. In the middle looks pollen as a means of pollination. in the morning many insects perch on the flowers.

That is all and thank you, regard...
