In some the protoplasmic contents may persist, in others they disappear.
If its contents were like the reports she'd seen in the past, it would be full medical nonsense.
In the Cyanophyceae the contents of the cell are differentiated into a central colorless region, and a peripheral layer containing the chlorophyll and other coloring matters together with granules of a reserve substance called cyanophycin.
Tissues.The component parts of the tissues of which plants are composed may consist of but slightly modified cells with copious protoplasmic contents, or of cells which have been modified in various ways to perform their several functions.
Sieve Tubes.The sieve tubes consist of partially fused rows of cells, the transverse cr lateral walls being perforated by minute openings, through which the contents of the cells are connected with each other, and which after a certain time become closed by,the formation of callus on the sieve plates.
Pulling the contents out, she stared at the ultra sound.
Fred had emptied the carton and spread the contents on the office floor.
Beneath the epidermis is a longitudinal layer of muscle-fibres which are separated into four distinct groups by the dorsal, ventral and lateral areas; these are occupied by a continuation of the epidermic layer; in the lateral areas run two thin-walled tubes with clear contents, which unite in the anterior part of the body and open by a pore situated on the ventral surface usually about a quarter or a third of the body length from the anterior end.
(After Kleinenberg, from Gegenbaur.) access of water to the contents; when the cnidocil is stimulated it sets in action a mechanism or perhaps a series of chemical changes by which the plug is dissolved or removed; as a result water penetrates into the capsule and causes its contents to swell, with the result that the thread is everted violently.
What, however, with the idealists was an object of thought alone, the absolute, is to Lotze only inadequately definable in rigorous philosophical language; the aspirations of the human heart, the contents of our feelings and desires, the aims of art and the tenets of religious faith must be grasped in order to fill the empty idea of the absolute with meaning.
It is evident that if our experiments are solely directed to the verification of this law, they should, if possible; be carried out in a hermetically closed vessel, the vessel and its contents being weighed before and after the chemical change.
His papers were sensational in form and contents and had an enormous popular circulation.
There Seems A Fairly Well Marked Annual Variation In Ionic Contents, As The Following Figures Will Show.
In the 19th century the doctrine of evolution received new biological contents and became transformed from a vague, partly metaphysical theory to the dominant modern conception.
A description of the contents of all these books in the canon is given in Rhys Davids's American Lectures, PP. 44-86.
The cells of hairs may have living contents or they may simply contain air.
The sieve-tubes differ, however, from the tracheids in being immediately associated, apparently constantly, not with starchy parenchyma, but with parenchymatous cells, containing particularly abundant proteid contents, which seem to have a function intimately connected with the conducting function of the sieve-tubes, and which we may call proteid-cells.
In some cases (Allium, Convolvulaceae, &c.) rows of cells with latex-like contents occur, but the walls separating the individual cells do not break down.
The naked cells which have been alluded to live in water, and call therefore for no differentiation in connection with this necessity; but those which are surrounded by a cell-wall always develop within themselves a vacuole or cavity which occupies the greater part of their interior, and the hydrostatic pressure of whose contents keeps tha protoplasm in contact with the membrane, setting up a condition of turgidity.
It was formerly the custom to regard as parasites all those pants which inserted roots or root-like organs into the tissues of other plants and absorbed the contents of the latter.
It has the appearance of a delicate tube which has granular contents, and is provided withani apexthatappears to be open.
As the tube grows down the hair it maintains its own independence, and does not fuse with the contents of the root-hair, whose protoplasm remains quite distinct and separate.
If a mass of living plant-tissue is cut, the first change observed is one of color: the white flesh of a potato or an apple turns biown as the air enters, and closer examination shows that cell walls and contents are alike affected.
The spot or patch is an area of injury; on (or in) it the cell-contents are suffering destruction from shading, blocking of stomata, loss of substance or direct mechanical injury, and the plant suffers in proportion to the area of leaf surface put out of action.
The opening, which is at first very small, increases in size, and before the cross-wall has entirely disappeared the contents of the two cells become continuous (Scott).
The contents of the volumes of Migne's patrologies are given in the Catalogue general des livres de l'abbe Migne, and a useful list in alphabetical order of the writers in the Greek Patrologia has been compiled by Dr J.
At dinner the conversation did not cease for a moment and seemed to consist of the contents of a book of funny anecdotes.
Something was boiling in a small cauldron at the edge of the fire and a soldier in a peaked cap and blue overcoat, lit up by the fire, was kneeling beside it stirring its contents with a ramrod.
He detailed the man's selection of clothes and the contents of his medicine cabinet as he shaved.
Pushing the door open with his foot, he dropped the contents of his arms on the bed and opened the dresser drawers.
Hating himself for it, he walked directly to the dresser and drank the entire contents of the large carafe of blood he found there.
Contents of the two cells fuse together, cytoplasm ~ B
If the attack of a parasite is met by the formation of some substance in the protoplasm which is chemo- tactically repulsive to the invader, it may be totally incapable of penetrating the cell, even though equipped with a whole armoury of cytases, diastatic and other enzymes, and poisons which would easily overcome the more passive resistances offered by mere cell-walls and cell-contents of other plants, the protoplasm of which forms bodies chemotactically attractive to the Fungus.
Then come the glandular surface (C), which is formed of smooth polished epidermis with numerous glands that secrete the fluid contents of the pitcher, and finally the detentive surface (D), of which the cells are produced into long and strong bristles which point A FIG.
An account of the contents of these manuscripts was given by Mark Napier in the appendix to his Memoirs of John Napier, and the manuscripts themselves were edited in their entirety by him in 1839 under the title De Arte Logistica Joannis Naperi Merchistonii Baronis Libri qui supersunt.
