A corn plant produces both male and female flowers. The male flower forms the tassel and the female flower forms the ear on the corn. the silks that emerge from the ear are the stigma of the female flower. each silk leads to an ovule that can become a corn seed. which of these must happen for corn seeds to develop on the ear? F : more tassels than silks need to be present on the same plant
G: pollen grains must fall from tassels and land on the silks of the ear
H: pollen must be transported from the tassel to the silk through the phloem.
J: the tassels must come into direct contact with the silks of the ear
