So next time you have your peas or corn remember that the former is a dicot while the latter is a monocot. Summary: 1.Monocots are single seeds while dicots seeds can be split into two halves. 2. The flowers of monocots have petals in multiples of three while dicot flowers have in multiples of 4 or 5.
Some examples of monocot seeds are maize, rice, wheat, coconut, grasses, etc. Dicot seeds contain two cotyledon, which are thick and fleshy. The cotyledon is responsible for the absorption of nutrients from the endosperm before the germination of the seed. Some common examples of dicot seeds are pea, bean, peanut, apple, etc. Each dicot seed has a unique seed coat, which provides a distinctive appearance. Testa is the outer layer of seed coat, which protects the seed from damage and prevents it from drying out. Tegmen is the thin layer lying next to testa.
