A bean seed is a Dicot.
• Seed coat
• The bean seed has a split going down the middle
of the seed.
• The two large parts of the seeds are called
cotyledons.
Cotyledons supply food for the young plant as its
growing.


Monocots are seeds that only have 1
cotyledon, such as the corn seed, The corn
seed has a seed coat but it does not slip off
as easily as the bean seed does.
It stays in one piece.
