PLANT EMBRYO with COTYLEDONS (or Seed Leaves), RADICLE and HYPOCOTYL (Capsella bursa-pastoris, Shepherd's Purse), 25X. The two cotyledons are in the seed and store food that is utilized by the embryo. This plant is a dicot (has two cotyledons). The radicle produces the primary root. Monocot plants have a single cotyledon. In dicots, the hypocotyl extends above ground and gives rise to the stem of the plant. The red cells on the outside are part of the seed coat which provides protection for the embryo.
