Question

Runners and rhizome : _________________;

Sporangia of Pilobolus: ________________.

• A. Apogeotropism , chemotropism
• B. Diageotropism, phototropism
• C. Plageotropism , geotropism
• D. Thigmotropism , hydrotropism

Answer 1

Answer:

B. Diageotropism, phototropism

• Runners and rhizomes: These grow horizontally at right angles to gravity. This phenomenon is called 'Diageotropism'.

• Sporangia of Pilobolus: The sporangiophores of this fungus grow toward light (positive phototropism) and subsequently aid in discharging spores. Therefore, it exhibits 'Phototropism'.
