What is a seeds food supply?
Seeds. A seed is a mature, fertilized plant ovum containing an embryo, a food supply, and a protective covering called the testa, or seed coat.
Where does a seed gets its first food?
cotyledons
The cotyledons are the first seed leaves and can store food for the embryo but also aid as a food source once the plant germinates. The perisperm is storage tissue that is only found in a few plant families. It is usually digested by the endosperm during seed development.
Do seeds have a food supply?
Seeds carry the food that helps the new plant begin to grow. This food store is in the endosperm, and/or in the cotyledons. Many kinds of seeds are good food for animals and people.
Where does the food in a seed come from?
During the formation of seeds, plants store their food like oils, starch and protein inside the seed. This food is stored so that a growing embryo may use it for nourishment. When the seed consumes water then hydrolytic enzymes are activated and stored food is converted into metabolic chemicals.
Where does the food for germination come from?
In most of the germinating seeds, the food for the nourishment of the seed is reserved in the seed coat. When the seed gets suitable conditions then it starts germination and takes the food from the seed coat. Now you must be surprising that from where does food come in the seed coat?
Where do seedlings get the food they need?
Cotyledons are the seed leaves and they also contain storage of food for the developing plant. The cotyledons in many cases perform major photosynthetic producers during germination. Mature seedlings get their food from photosynthesis done by young leaves, just like adult plants.
Where do germinating seeds get their energy from?
Germinating seeds get their energy by breaking down stored food material in endosperm of a seed. This role is later taken up by cotyledons in growing seedlings.

Why does a seed need a food store?
All seed plants store food within the seed; this takes the form of the cotyledons which are there to provide nutrition to the embryo while it is dormant and then while the seed is germinating and before it is able to produce its own food Where do plants store their extra food? Plants store extra food in the central vacuole
