Amber contains plants of 100 million years old

American and European researchers said that a plant preserved in amber about 100 million years ago revealed evidence of sexual reproduction of flowering plants. Wrapped in amber flakes is 18 tiny flowers from the Cretaceous period, some of which are in the process of being developed to transfer seeds to the next generation.

UPI news agency quoted biologist George Poinar from the University of Oregon, although the "confined" plant model in this amber was extinct in the mid-Cretaceous period, but it is a testament to flowering plants changing the surface of the earth, leading to the diversity and development of organisms today.

Through microscopic research, scientists in Oregon and German colleagues discovered from the development of pollen tubes, some pollen grains are penetrating female reproductive systems. Scientists were also surprised when the amber drops fell to this cluster of flowers very quickly and preserved very well to this day.

At the beginning of the Cretaceous period, plants on the earth are mainly coniferous trees, ferns, moss . Then the flowering plants gradually formed and developed, at that time dinosaurs were still dominating the planet. UPI quoted Poinar as saying that the evolution of flowering plants has created a huge change in biodiversity for life on earth, especially in tropical and subtropical regions.
