You will notice the apple with 5 places where seeds will grow. This corresponds with five petals of the apple flower (I believe). The last photo here is an apple seedling and also another just coming up. You see the hypocotyl as an upside down U with the remnants of its seed. Within the seed are the beginning leaves (cotyledons). Apple trees are dicots compared to monocots. Grass and corn are monocots. Dicots are plants that come up having two beginning leaves.
