Executory and Executed Contracts. An executory contract has an act or obligation stipulated in a contract that has yet to be performed by one or more parties to the contract. For example, an equipment lease and a license to intellectual property are examples of executory contracts.
The seed contains and disperses the embryo. Around the whole seed is a layer called the seed coat. This layer may be thick or thin, depending on the species, but it often contains light-sensitive chemicals.When conditions are right -- there is appropriate light and water -- the seed coat may trigger the germination of the seed.his layer may be thick or thin, depending on the species, but it often contains light-sensitive chemicals.

A seed is an embryonic plant enclosed in a protective outer covering known as the seed coat. It is a characteristic of spermatophytes (gymnosperm and angiosperm plants) and the product of the ripened ovule which occurs after fertilization and some growth within the mother plant.eeds have been considered to occur in many structurally different types (Martin 1946). These are based on a number of criteria, of which the dominant one is the embryo to seed size ratios. This reflects the degree to which the developing cotyledons absorb the nutrients of the endosperm, and this obliterate it.
