I've got these sunflower seedlings - most of which like the one in the
bottom of the picture have two cotyledons and paired leaves.
It is tricotyledonous, most flowering plants are bicotyledons and grasses
are monocotyledons. It will probably have a thickened stem and you may get
some odd shaped flowers.

I've got this on two of my Shirley tomato seedlings - I'm going to be
interested to see how it affects fruiting.
