A collection for comparing the germination of rye (10 times enlarged), bean (5 times enlarged), and spruce (20 times enlarged). The model clearly demonstrates that: 1. the rye (Secale cereale) seed pushes up from the soil a shoot - monocotyle plant, 2. the bean (Phaesolus vulgaris) first appears as a two leaved shoot - dicotyle plant and 3. the shoot of the spruce (Picea excelsa) appears from the earth by unfolding their star-shaped cotyledons. Separable into 8 parts. On a base with key.
