What are cotyledons?

Hint: A cotyledon is a portion of the embryo inside the grain of a plant. Often while the seed grows or starts to grow, the cotyledon may enhance the first petals of the seedling.

Complete Answer:
- Cotyledons are the first leaflets dropped by plants. Cotyledons are not supposed true petals and are sometimes pointed to as "seed petals," because they are a portion of the seed or nucleus of the plant. The seed leaflets assist to obtain the saved nutrients in the seed, nurturing it until the true petals grow and produce photosynthesizing.
- Flowering plants are classified into two categories: Monocotyledones (monocots) and Dicotyledones (dicots). As the names suggest, the main variation is the number of cotyledons existing in the seed nucleus–1 or 2.
- Monocots consist of bulbing plants and seeds, such as bamboo, corn, asparagus, agapanthus, daffodils, bananas, garlic.
- Dicots involve numerous of the most commonly planted greenhouse flowers and legumes, including the cabbage family, and the aster species, such as apples, berries.
- Cotyledons produce the seed with the food supplies for the nurture of the embryo while germination (Contains particularly starch) is a major function of cotyledons.
- A valuable role of the cotyledon is to assist botanists to divide flowering shrubs, also known as angiosperms.

Note: Not all plants have cotyledons, which suggests they are not monocots or dicots. Plants that produce spores, such as pteridophytes, and plants that form seeds, as with most pines, do not have cotyledons. However, all plants that shoot can be classified into unless monocots or dicots.
