The fern Tmesipteris oblanceolata, which scientists just discovered has the longest known genome of any organism. Ferns are known among scientists for having particularly large genomes.

This Tiny Fern Has the World's Largest Known Genome

The plant's genome has about 50 times as many base pairs as a human's, and its DNA from a single cell would stretch longer than a football field

Acorns cover the forest floor.

Why Do Trees Drop So Many Seeds One Year, and Then Hardly Any the Next?

A new paper suggests that plants may use slow seed years to prevent the spread of disease
