Cannabis achene and embryo microstructure, cotyledons, radicle position, storage organelles, reserve mobilization, and structural changes during germination.
Visual lesson 04
Cotyledon transition
Track emergence from the seed shell through cotyledon opening and the first true leaves.
Interactive academic visual
Cotyledon transition
Seed reserves support emergence before true leaves take over photosynthetic workShell release
The emerging seedling sheds or escapes the seed coat as the hypocotyl and cotyledons expand.
