A seed spends its reserve.

Can a seed swell without becoming a seedling?

Setting up the mechanism…

Radicle length: 0.00mm
Reserve spent: 0.00mg

Seed swelling: Can imbibe water

Fit the specimen and set conditions before running.

Can a seed swell without becoming a seedling?

Water permits imbibition, but growing embryo cells also need oxygen and a suitable temperature. Cotyledon reserves supply the early seedling before it has expanded leaves.

stored reserve → respiration + seedling tissue

What this model simplifies

Nondormant bean-type seed before leaf expansion; no light requirement in this selected case. Illustrative triangular temperature window 10–35°C, peak 25°C; not a species calibration.
