An imperfect flower is either _ (has stamen but no pistil) flower.

A

staminated

38
Q

T/F
An incomplete flower is an imperfect flower, but an imperfect flower may or may not be an incomplete flower.

Q

Pollination is the transfer of pollen grains from the _ of a stamen to the _ of the pistil.

A

anther, stigma

Self Pollination

41
