Adaptations of flowers to wind and insect pollination practice exercise 3

In a busy Nairobi estate, a butterfly garden was planted, but insects rarely visited. The flowers had scent and nectar. Based on flower adaptations, explain why insects may have failed to locate the flowers.  (2 marks)

During a school trip to a windy hillside in Nyandarua, learners observed a flower with long, hanging anthers and feathery stigmas (as shown in the image). One pupil asked why this flower looked so plain compared to others in the garden. Based on its structure, explain how this flower is adapted for pollination.  (2 marks)

A student compared two maize farms: one planted during the dry windy season and the other during rainy season. The dry-season maize had better seed formation. Explain the difference using flower adaptations.  (2 marks)

A class visited a garden with both dull and bright flowers, as shown below. Some had feathery stigmas, others had scent and nectar. How can learners tell which flowers depend on wind and which on insects?  (2 marks)

A farmer in Kajiado grew a new variety of grass in a sheltered valley with little wind movement. The plants grew healthy but did not produce seeds. Explain how the location affected pollination based on the flower’s adaptations. (2 marks)
