He did not attain the excellence of Giovanni Bellini, nor did he give the same grandeur to his proportions, and the same enlargement of the ancient style, although he continued to flourish until the year 1535.

He richly deserves a place in history as the instructor of Paolo, an artist excellent in many branches of painting, and in architecture almost divine.
It is supposed that Paolo must have acquired this degree of excellence by studying at first under Carotto, and afterwards perfecting himself, as we shall shew, by means of Badile.
Among other figures is a Madonna, between two angels, upon a large scale, and in good design, sufficient to entitle Pietro to an honourable rank in the history of art.
He had also been a scholar or rather imitator of Jacopo Bellini, to whose style, says Vasari, he invariably adhered.
His brother Giovanni, a noble architect, and designer of ancient edifices, was but a feeble imitator of his style.
In this instance the seed may be exalbuminous, and the embryo may be folded on itself; or albuminous, the embryo surrounding more or less completely the endosperm and being peripherical.
Upon the side of the embryo next the endosperm and enveloping it is a large shield-shaped body, termed the scutellum.
The endosperm formed in the embryo-sac of angiosperms after fertilization, and found previous to it in gymnosperms, consists of cells containing nitrogenous and starchy or fatty matter, destined for the nutriment of the embryo.
In grasses, by the enlargement of the embryo in a particular direction, the endosperm is pushed on one side, and thus the embryo comes to lie outside at the base of the endosperm (figs.

When the embryo is surrounded by the endosperm on all sides except its radicular extremity it is internal (see figs.
The relative size of the embryo and of the endosperm varies much.
In Monocotyledons the embryo is usually small, and the endosperm large, and the same is true in the case of coffee and many other plants amongst Dicotyledons.
As the endosperm increases in size along with the embryo-sac and the embryo, the substance of the original nucellus of the ovule is gradually absorbed.
It will be observed further that the endosperm is filled with a network of thin-walled cells closely packed with starch granules, and smaller granules of protein matter (fig.
The embryo lies embedded in a mass of cells, the part dividing it from the endosperm being known as the scutellum.
The mealy appearance in the endosperm of barley is assumed to be a direct consequence of the formation of interspaces around the cell-contents and within the cell walls.
This deformation is followed by complete disintegration of the nucleus, and at the end of seven or eight days nearly the whole of the endospermhas been involved.
The endosperm of green malt which is ready for the kiln should be soft and mealy, and should not exude moisture when pressed between the thumb-nails, but should crumble and disintegrate to a chalky mass having little or no adhesiveness.
Gruss has pointed out that the action which takes place on the cell walls of the endosperm during germination does not consist in their complete solution.
In properly made malt the modification of the endosperm should proceed pari passu with the growth of the acrospire.
The contents of the endosperm should present a white friable or mealy appearance when the corns are bitten or cut in two with a penknife.
Moisture must also be carefully excluded, as it initiates germination in a few cells only of the endosperm and causes heating.
Brown has shown recently that the embryo and endosperm of a barleycorn are enclosed in a semi-permeable membrane, i.
These three products of roller mills are practically identical in composition, but represent different stages in the process of reducing the endosperm of the wheat to flour.
This is an important organ as its function is to absorb nourishment from the endosperm during germination.
The caryopsis consists of an embryo on one side at the base and the endospermoccupies the remaining portion.
Just outside the endosperm and within the epidermis lies a layer of cells containing much proteid substance.
Cross section of bean showing folded endosperm with hard and soft tissues.
His work with normal, caffein-free coffee and with Thum's purified coffee led him to state that a part of these substances was derived from the crude fiber, probably from the hemi-cellulose of the thick endosperm cells.
The grains of the cereal crops become shrunken as a result of potassium starvation; and are plump and well filled with starch in the endosperm when sufficient potassium is available for the crop's needs.
Extracellular enzymes are also developed in seeds during germination, in order that the stored food material of the endosperm may be rendered soluble and translocated into the tissues of the growing seedling.
The part in contact with theendosperm is plate-like, and is known as the scutellum; the surface in contact with the endosperm forms an absorptive epithelium.
Its position is remarkable, closely applied to the surface of the endosperm at the base of its outer side.
The testa is thin and membranous but occasionally coloured, and the embryo small, the great bulk of the seed being occupied by the hard farinaceous endosperm (albumen) on which the nutritive value of the grain depends.
Thirdly, the outermost layer or layers of cells of the endosperm are filled with proteids, and are known as the Aleurone layer.
The dark line e represents the surface where the face of the scutellum is applied to the endosperm and where absorption of the latter takes place.
The only case of purely vegetative cell-formation which takes place by either of these processes is that of the formation of endosperm in Selaginella and phanerogams, which is a process of free-cell formation.
He followed the pollen tube to the tip of the embryo-sac and the development of the endosperm in its upper portion, where the embryo appeared.
In some speculations concerning the embryology of Loranthus he came, by a wrong line of approach, within touch of the right comparison, when he compares the endosperm to the confervoid green growth (i.
He saw the growth of the endosperm leading to its complete protrusion from the ovule and inverting the embryo so that its cotyledons point to the surface.
The cells of this tissue become filled with starch, and serve the same purpose as the endosperm of other seeds.
The fruits resemble those of the sedges, but the embryo is usually larger and placed at one side of the endosperm (N, em.
The embryo is small, surrounded by abundant endosperm (Fig.
In the suborders Mimosoideae and Papilionatae the embryo fills the seed or a small quantity of endosperm occurs, chiefly round the radicle.
In Caesalpinioideae endosperm is absent, or present forming a thin layer round the embryo as in the tribe Bauhinieae, or copious and cartilaginous as in the Cassieae.
The study of a thin section of the corn grain under the compound microscope shows us that the starch grains in the endosperm are large and regular in size.
Although we find a little starch in the corn cotyledon, still it is evident from our tests that the endosperm is the chief source of food supply.
This kernel consists of the embryo plus the endosperm or its remains.
The large size of the endosperm and the thick and complex seed-coats are characteristic features of both these structures.
Seed Essentially similar to the preceding, except in the possession of an embryo e, which is, however, small in comparison with the endosperm which fills the spore S.
The corn pushed a slender growing point to the surface leaving the cotyledon and endosperm behind in the soil but still attached to the little plant (Fig.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "endosperm" in a variety of sentences. We hope that you will now be able to make sentences using this word.
