NEET BIOLOGY

Detailed explanation-1: -Hyphal growth is greatly influenced by stimuli and will grow toward a food source, water, or even toward reproductive units of other fungi. Collectively, a mass of hyphae are referred to as a mycelium.

Detailed explanation-2: -Hyphal tip growth is initiated by establishment of a growth site and the subsequent maintenance of the growth axis, with transport of growth supplies, including membranes and proteins, delivered by motors along the cytoskeleton to the hyphal apex.

Detailed explanation-3: -The basic unit of a filamentous fungus is the hypha, which usually consists of a chain of elongated cells that expand at the apex of the tip cell (10, 41, 115). Hyphal tip growth is characterized by the initial establishment of one growth site, which is followed by its continuous maintenance.

Detailed explanation-4: -The environmental conditions required by the fungi are: warm temperatures, moisture, poor ventilation and the presence of oxygen. Wood fungi will not grow if temperatures are too low (optimum temperature is between 70º and 90º F), the moisture content is less Page 2 72 than 20%, and if oxygen is absent.
