Floral parts typically become part of the seed and/or the fruit. 1. Obtain a germinated bean and use p. 145 of the atlas as a guide. The pod that housed the bean is the fruit of the bean plant. The bean is the seed of the plant. 2. The papery outer red covering of the bean is the seed coat, which developed from the integuments of the ovule. g eno le al boez 3.
