and which is female?
Female – stigma
Male – anthers
What does it mean if a plant is
true-breeding and what does I mean
True-Breeding means that an
offspring will have the same
characteristics as the parent plant.
Cross-pollination means that the anthers are removed from one plant and pollen from another plant pollinates that plant.
