Endosperm
Endosperm explained in an easy to understand way:
Imagine you're preparing for a long road trip, and you need to pack enough snacks and drinks to keep you energized along the way. Similarly, an endosperm acts like a packed supply of food for a growing angiosperm embryo, ensuring it has the necessary nutrients to develop. Just as your snacks fuel your journey by providing energy and sustenance, the endosperm nourishes the plant embryo, giving it the resources it needs to grow until it can sustain itself.
