cotyledon
There is no food supply for seeds but there is a food supply for animals that eat seeds is called food seed supply.
Like all other plants, the growth or germination of a seed is affected by the food supply by how abundant or how scarce it happens to be. A seed which needs special requirements may be very senstive to the amount of available food.
The food supply stored in a seed is called endosperm. It provides essential nutrients for the developing embryo until it can photosynthesize on its own.
A monocot stores its food supply in the endosperm of the seed. Dicots store the bulk of their food in the two cotyledons.
The complete package containing an embryonic plant and its food supply is called a seed. The seed consists of an embryo (the young plant) and endosperm or cotyledons (the food supply) enclosed within a protective seed coat. This structure allows for the plant to survive and germinate when conditions are favorable.
an embryo, the endosperm (food supply), and the seed coat.
Petals
If you are referring to a seed, then the embryo, the food store and the seed coat. If you actually mean the embyo itself, then precursor tissues for the leaves, stem and root, as well as one or more cotyledons.
Portions of the seed supply food for the plant before it emerges from the soil. The plant's seed actually stores food for use during the germination phase of growth.
The endosperm, which contains both the embryo and its starchy food supply.
