Here's a breakdown:
* Endosperm: A tissue within the seed of flowering plants that provides nourishment to the developing embryo. It is typically formed by the fusion of a sperm cell with two polar nuclei within the female gametophyte (embryo sac).
* Embryo: The developing plant within the seed.
* Seedling: A young plant that has emerged from the seed and is able to photosynthesize and grow independently.
How it works:
The endosperm contains stored nutrients like starch, proteins, and oils. As the embryo grows, it absorbs these nutrients from the endosperm, providing the energy and building blocks it needs to develop. Once the seedling emerges from the seed and develops leaves, it can begin producing its own food through photosynthesis, making it self-supporting.
Examples:
* Grains: The endosperm of grains like wheat, rice, and corn is the primary source of food for humans and animals.
* Nuts: The endosperm in nuts like almonds and cashews is also a rich source of nutrients.
