Fat and glycogen
The fleshy part of the seed is called the cotyledon. This is the part of the plant where food is stored. Some seeds have one cotyledon, for example corn, and other have two cotyledons, for example a lima bean.
A monocot stores its food supply in the endosperm of the seed. Dicots store the bulk of their food in the two cotyledons.
For the most part foods were stored by cooking and salting them, like making beef jerky for example. This allowed the foods to last through the winter.
when a seed begins to grow the young plant uses the food stored in the seed. the spores of the seedless plants dont have stored food to help a new plant grow.
The shelf life of dehydrated food is typically one to two years when stored in a cool, dry place.
A dicot seed
Life cycle of seed : Seed Coat - Protects the inside of the seed. Embryo - the beginning of the new plant. Endosperm - Stored food in a monocotyledon. Stored Food - a plant uses stored food until it grows leaves that can make food. Monocot - a type of seed that has only one cotyledon. Dicot - a type of seed that has two cotyledons. Cotyledon - Leaf-like structure that absorbs and digest food stored in the seed. Germination - the process of growing a new plant from a seed.
Cross contamination: for example storing raw chicken above salad greens; the salad greens are contaminated with salmonella. Time/Temperature abuse: Foods stored in the temperature danger zone; 41-164 degrees.
Seeds need a supply of stored food to provide energy for germination and initial growth before they can photosynthesize. This stored food source ensures the seedling has enough energy to establish itself and begin growing into a mature plant. It also increases the chances of successful germination and survival in challenging conditions.
Food that is stored inside of a seed is said to be stored in dormant form. This means that the seed will not grow until it is in a place with plenty of good soil, food, and water.
Two examples of polysaccahrides are cellulose (makes up plant cell walls) and glycogen (which is how carbohydrate is stored in the cells of the body).
Two different producers are grass and trees or a forest farmland food chain or in an ocean habitat alga for example.
