are seeds derived from an ovule
Lecture 17. Seed and Fruit Development. The seed develops from the ovule and contains the embryo and endosperm, surrounded by the maternally derived seed coat. The function of the seed is to protect the embryo, to sense environmental conditions favorable to germination and to nourish the germinating seedling.n early development all angiosperm seeds also contain an endosperm, but in many seeds the endosperm is completely absorbed by the developing embryo. The embryo and endosperm are products of fertilization while the seed coat develops from the integuments of the ovule. 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.n endospermic seeds, there are two distinct regions inside the seed coat, an upper and larger endosperm and a lower smaller embryo. The embryo is the fertilised ovule, an immature plant from which a new plant will grow under proper conditions. Frequently associated with accessory structures (such as receptacle tissue). Seed = ripened ovule. C. Fruits vs. veggies Botanically, fruits are derived from the ovary or reproductive parts of the plants. Vegetables are derived from vegetative parts, such as leaves, roots and stems.. Seed coat (also called the testa) - the suitcase. It is derived from the integuments of the ovule. Thus, it is maternal tissue (the only part of the seed that is not part of the new generation). The seed coat is primarily for protection. The seed coat may have hairs (i.e., cotton) or other appendages. The seed coat develops from the material tissue, the integuments, originally surrounding the ovule. The 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.n endospermic seeds, there are two distinct regions inside the seed coat, an upper and larger endosperm and a lower smaller embryo. The embryo is the fertilised ovule, an immature plant from which a new plant will grow under proper conditions. In early development all angiosperm seeds also contain an endosperm, but in many seeds the endosperm is completely absorbed by the developing embryo. The embryo and endosperm are products of fertilization while the seed coat develops from the integuments of the ovule.The seed coat contains a variety of adaptations related to protection and dispersal mechanisms.n early development all angiosperm seeds also contain an endosperm, but in many seeds the endosperm is completely absorbed by the developing embryo.

A fruit consists of pericarp, that develops from the ovary wall, and seed derived from ovule. 2  The pericarp may be thin or thick and is usually differentiated into an outer epicarp, a middle mesocarp, and an inner endocarp. 3  But in dry fruits, the pericarp is undifferentiated and is usually papery or woody. seed potatoes, seeds of corn or sunflower seeds . In the case of sunflower and corn seeds, what is sown is the seed enclosed in a shell or husk, whereas the potato is a tuber. Many structures commonly referred to as seeds are actually dry fruits.n endospermic seeds, there are two distinct regions inside the seed coat, an upper and larger endosperm and a lower smaller embryo.

In endospermic seeds, there are two distinct regions inside the seed coat, an upper and larger endosperm and a lower smaller embryo. The embryo is the fertilised ovule, an immature plant from which a new plant will grow under proper conditions.The embryo has one cotyledon or seed leaf in monocotyledons, two cotyledons in almost all dicotyledons and two or more in gymnosperms.n endospermic seeds, there are two distinct regions inside the seed coat, an upper and larger endosperm and a lower smaller embryo. The embryo is the fertilised ovule, an immature plant from which a new plant will grow under proper conditions. A fruit is a matured ovary containing one or more seeds. In flowers, the ovary is a protective vessel in which ovules are nourished to their mature form, seeds. Within this vessel, the ovules remain attached to parent tissue along zones of placentation. These zones of placentation are known as carpels.n flowers, the ovary is a protective vessel in which ovules are nourished to their mature form, seeds.
