He introduced bacteria into liquid sterile nutrient gelatin.
To effect this some of the nutrient gelatin containing yeast cells is placed on the under-surface of the cover-glass of the moist chamber.
The spore-cell multiplies by division, while the enveloping cell is nutrient and protective.
A soft nutrient substratum penetrate it and become absorbing organs.
Besides the aphids, other insects, such as scale insects (Coccidae), caterpillars of blue butterflies (Lycaenidae), and numerous beetles, furnish the ants with nutrient secretions.
The cell body, or cytoplasm, is apparently composed of a fine reticulum or network, containing within the meshes a soft viscid, transparent substance, the cell-sap, or hyaloplasm, which is probably a nutrient material to the living cell.
In the female, each ovary consists of a large number of ovarian tubes, in which swollen chambers containing the egg-cells alternate with smaller chambers enclosing nutrient material.
Maculosa, but as a rule only one fully develops in each uterus, the embryo being nourished on the yolk of the other eggs, which more or less dissolve to form a large mass of nutrient matter.
The yeast-conidia, which bud off from the conidia or their resulting mycelium when sown in nutrient solutions, are developed in successive crops by budding exactly as in the yeast plant, but they cannot ferment sugar solutions.
" When the antlers are freed from the velvet - a process usually assisted by the animal rubbing them against tree stems or boughs - they have a more or less rugose surface, owing to the grooves formed in them by the nutrient blood-vessels.
Sensors can constantly monitor moisture levels in the soil, the size and color of the plants, air quality, nutrient levels in the soil, amount of sunlight, and hundreds of other variables.
