Detailed explanation-1: -cotyledon, seed leaf within the embryo of a seed. Cotyledons help supply the nutrition a plant embryo needs to germinate and become established as a photosynthetic organism and may themselves be a source of nutritional reserves or may aid the embryo in metabolizing nutrition stored elsewhere in the seed.
Detailed explanation-2: -Final answer: A baby plant called an embryo is inside the seed coat.
Detailed explanation-3: -The embryo’s food, called endosperm, may be in the seed leaves (also called cotyledons) or it may be outside the seed leaves and be absorbed as the seed germinates. Endosperm food sources can be in the form of carbohydrates, proteins, or fats.
Detailed explanation-4: -In addition, the seed contains a food supply – called the endosperm – that is packed with nutrients to keep the seed nourished and allow it to grow. As the embryonic plant develops, the seed leaves, or cotyledons, absorb the food supply and continue to nourish the plant.
Detailed explanation-5: -A seed consists mainly of carbohydrates and these have to be is transported from the leaf where they are assimilated into the seed’s outer coat from the parent plant and then accessed by the embryo. If not enough food is delivered, the seeds won’t have the energy to grow when it’s time to germinate.
