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.
The spore-cell multiplies by division, while the enveloping cell is nutrient and protective.
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.
Besides the aphids, other insects, such as scale insects (Coccidae), caterpillars of blue butterflies (Lycaenidae), and numerous beetles, furnish the ants with nutrient secretions.
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.
