fertilization | egg nucleus joins with pollen grain nucleus |
stamen | male reproductive organ; anther, filament |
carpel | female reproductive organ; stigma, style, ovary, ovule |
egg cell | female sex cell |
pollen grain | male sex cell |
cross-pollination | creates new variety; pollen from one flower carried by wind/animal to stigma of another flower |
How does nature protect against self-polliation? | 1. Plants have only male flowers or female flowers; 2. Pollen released, anthers split and die, stigmas mature and are ready to accept pollen |
How does pollen travel? | Animal or wind |
