Tropical orchids are mostly epiphytal - that is, they grow upon trees without deriving nourishment from them.
Ten years before, John Worlidge, one of his correspondents, and the author of the Systema Agriculturae (1669), observes, " Sheep fatten very well on turnips, which prove an excellent nourishment for them in hard winters when fodder is scarce; for they will not only eat the greens, but feed on the roots in the ground, and scoop them hollow even to the very skin.
For insects provided with a biting mouth, which take nourishment from the whole leaf, shoot or fruit, the poisonous washes used are chiefly arsenical.
Others are biennials producing a number of leaves on a very short stem in the first year, and in the second sending up a flowering shoot at the expense of the nourishment stored in the thick tap-root during the previous season.
The parasites, which cling to the intestinal mucous membrane, draw their nourishment from the blood-vessels of their host, and as they are found in hundreds in the body after death, the disorders of digestion, the increasing anaemia and the consequent dropsies and other cachectic symptoms are easily explained.
The effect of overwork upon an organ or tissue varies in accordance with (a) the particular organ or tissue concerned, (b) the amount of nourishment conveyed to it, and (c) the power of assimilation possessed by its cells.
In the case of muscle, if the available nourishment be sufficient, and if the power of assimilation of the muscle cells remain unimpaired, its bulk increases, that is to say, it becomes hypertrophied.
He showed that the gaseous constituents of the air contribute largely to the nourishment of plants, and that the leaves are the organs which elaborate the food; the importance of leaves in nutrition had been previously pointed out by Malpighi in a short account of nutrition which forms an appendix to his anatomical work.
One relates that he had no mother but was produced by Siva alone, and was suckled by six nymphs of the Ganges, being miraculously endowed with six faces that he might simultaneously obtain nourishment from each.
It does not supply the place of organic manures, but only renders that which is present available for the nourishment of the plants.
It is often resorted to as a means of restoring fertility in plants which have become over rank from an excess of nourishment in the soil, or sterile from want of it.
The greater number of them are epiphytes or plants that grow on others without absorbing nourishment from them, and heat and moisture afford all or nearly all the nourishment they require.
The number of years before flowering occurs depends on the vigour of the individual, the richness of the soil and the climate; during these years the plant is storing in its fleshy leaves the nourishment required for the effort of flowering.
PEMMICAN, a North American Indian (Cree) word for a meat prepared in such a way as to contain the greatest amount of nourishment in the most compact form.
A tapetal layer is derived from the cells surrounding the sporogenous group, and the arrest of a number of the spore-mother-cells further contributes to the nourishment of the remainder, each of which gives rise to four spores.
At the lower end of the albumen, and placed obliquely, is the minute embryo-plant, which derives its nourishment in the first instance from the albumen; this is destined to form the future plant.
For they cut the cheeks of the males with a sword, so that before they receive the nourishment of milk they must learn to endure wounds.
*Poisonous nourishment of a too sensitive soul, Thou, without whom happiness would for me be impossible, Tender melancholy, ah, come to console me, Come to calm the torments of my gloomy retreat, And mingle a secret sweetness With these tears that I feel to be flowing.
Discussions and questions of that kind, which are like the question of how to get the greatest gratification from one's dinner, did not then and do not now exist for those for whom the purpose of a dinner is the nourishment it affords; and the purpose of marriage is the family.
If the purpose of food is nourishment and the purpose of marriage is the family, the whole question resolves itself into not eating more than one can digest, and not having more wives or husbands than are needed for the family--that is, one wife or one husband.
