We read some information on the different kinds of fruit and how their seeds are different, but they all produce matching plants out of those seeds.
We also studied our nomenclature key cards and observed an actual fruit (an apple, cut in half).
Then he matched the 3-part nomenclature cards.
fruit, pericarp, exocarp, mesocarp, endocarp
I am looking into adding more parts the next time around (seeds, blossom end, stem, leaf).
