Document Summary

Can be fused to form tube: example: bell flower. Location of anthers: on top of the filaments. Plant sex is not as boring as animal sex. From tree to seed aka sex in plants: how to avoid doing it yourself. 4 main components to the a singe flower: Stamen: male productive system: components: anther & filament, carpel: female reproductive structure, components: stigma, style, ovary, sepals (inside of a flower) Function: protect inner flower organs before bud opens: before the flower is open, they are covered by green, non showy sepals, but as the flower opens, the sepal is hardly seen. Colour: frequently green: do(cid:374)"t waste a(cid:374)y (cid:272)olour pig(cid:373)e(cid:374)t o(cid:374) sepals. Can be fused to form tube: either individual separate sepals or fused sepals forms a tube. Carpel (female reproductive system) stigma: sticky landing platform for pollen: once the pollen lands, it sticks thus cannot be shake off easily.
