* Definition: Cotyledons are embryonic leaves present within the seed. They serve a crucial role in the early stages of plant growth.
* Function:
* Food storage: In many plants, cotyledons store food reserves (like starches, proteins, and lipids) that nourish the developing seedling until it can produce its own food through photosynthesis.
* Photosynthesis: In some plants, cotyledons are green and capable of carrying out photosynthesis, providing energy for growth.
* Protection: Cotyledons can also help protect the young shoot as it emerges from the soil.
* Types:
* Monocotyledons (monocots): These plants have one cotyledon, like grasses, corn, and lilies.
* Dicotyledons (dicots): These plants have two cotyledons, like beans, sunflowers, and oak trees.
In summary, seed leaves are essential for a plant's initial development and survival, providing food, energy, and protection until the seedling can establish itself.
