Slide 14
Multiple Fruit		 Complex Fruit - Multiple fruit develop from many individual flowers along a common inflorescence.  As the individual fruit grow and develop they fuse forming a single multiple structure.
Slide 15
Dry Dehiscent Fruit - Legume		 Opens along two seams to release seed.
Slide 16
Dry Dehiscent Fruit - Capsule		 Release seed by pores or multiple seams.
Slide 17
Dry Indehiscent Fruit - Caryopsis or Grain
Each individual grain of corn is an individual fruit.  The pericarp and the seed coat of a caryopsis are fused together and can not be separated.
Slide 18

The seed coat and the pericarp are not fused in the achene thus they can be separated.  Ex. Sunflower seed
Slide 19
