Compare the structure of a bean seed and a wheat caryopsis. What do they have in common? What is the difference? Draw a conclusion, what is the difference between the seeds of dicotyledonous and monocotyledonous plants.
The seeds of beans and wheat consist of an embryo: a root, a stalk, a bud with leaves and a cotyledon. And on top, the seeds are covered with a protective seed coat.
Beans have TWO cotyledons in the bud, which contain a supply of nutrients. Wheat has ONE cotyledon in the germ, which separates it from the ENDOSPERM, which contains a supply of nutrients.
Thus, the seeds of dicotyledonous and monocotyledonous plants differ in the number of cotyledons and the place where they store nutrients.
