Predict what's on your test 5 Must Know Facts For Your Next Test Cotyledons are classified into two types: monocotyledons (one cotyledon) and dicotyledons (two cotyledons). In monocots, cotyledons often remain below ground, whereas in dicots, they usually emerge above ground during germination. Cotyledons can vary significantly in shape and size between different plant species. They help jumpstart photosynthesis in seedlings until the true leaves develop and take over this function. Cotyledon presence is a key characteristic used to differentiate between major groups of angiosperms. Review Questions What is the primary function of cotyledons in seedling development? How do monocotyledonous and dicotyledonous plants differ in terms of their cotyledons? Why are cotyledons important for identifying different groups of angiosperms? "Cotyledons" also found in:
