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.
Pollen is produced by seed plants, both angiosperms and gymnosperms. Pollen has a cellulose wall around the protoplasm called the intine, outside this is the sporopollenin layer which is inert, very tough and resistent to bacterial attack, this layer is called the exine.he following images are of a representative selection of spores and pollen aimed at giving a general overview of the different morphotypes. Each specimen is given a generic and, if possible, a species name followed by its age range, the site location from which the sample was obtained and its size in microns.
