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

Answer 1

Answer:

B. Diageotropism, phototropism

1. Runners and rhizomes are types of vegetative structures used by plants for propagation.

2. Sporangia of Pilobolus exhibit phototropism, which is the directional growth response of plants towards or away from light.

Diageotropism is a type of tropism where plants grow at an angle to the gravitational force, often seen in roots.
