Question

How do flowering plants reproduce by fertilization if they are immotile?

Answer 1

3 is the answer because bees and such pollinate 

Answer 2

The right answer is 3)Insects and other organisms carry pollen to other flowers.

Entomophilia, also called entomophilous fertilization or entomogamy, is a mode of pollination in which insects participate in the transport of pollen, up to the stigma of the pistil in angiosperms and to the egg in gymnosperms.

The pollinating insects most likely to pollinate flowering plants belong to the order Hymemoptera, including bumblebees, osmies and bees raised by beekeepers. But other insects contribute to the multiplication of plants: the fly (Diptera), attracted by the smell of decaying meat it releases, ensures the multiplication of rafflesia.
