The Seed Coat Tough outer covering! Resistant to drying out Can not be digested!

THE ENDOSPERM The plants food source Made through the fertilization process, that’s where it gets its name The largest part of the seed!

THE PLANT EMBRYO Three parts to each embryo: Pre Leaves - Epicotyl Pre Stem - Hypocotyl Pre Root - Radicle

GYMNOSPERMS Literally means: NAKED SEED Produce seeds on scales Scales clustered on Cones .

Seeds form on these scales .
