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.
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.he seed coat in the mature seed can be a paper-thin layer (e.g. peanut) or something more substantial (e.g. thick and hard in honey locust and coconut), or fleshy as in the sarcotesta of pomegranate. The seed coat helps protect the embryo from mechanical injury, predators and drying out.
The seed can be planted to start this life-cycle over again. However, it is seed-chauvinism to start here. Many plants do not reproduce via seeds at all. Seed Structure. A seed consists of three parts: a Dormant Embryo, a Storage Tissue, and a Seed Coat. Not every seed that has evolved on this planet has precisely the same structure. In some seeds, the endosperm is retained as the storage tissue. In other seeds, the endosperm is more or less used up to put storage chemicals into the embryo itself (commonly in the cotyledons). Below is a diagram of two hypthetical seeds.
