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 kernel of the seed is the core of the operating system, providing operating system services to applications programs, which is surrounded by the shell of the seed that is what users see from the outside. Some people want to tie kernel (and, indeed, shell) down to be more specific than that.
