Question

The drawing shows a longitudinal section through a flower, From the drawing, say whether you think the flower might be pollinated by the (a) wind, (b) ants, (c) butterflies or (d) bees. Explain the reason for your answer.

Accepted Answer

The flower is a delicate and highly specialised part of the shoot system. It contains the structures that are needed for reproduction.

The above drawing of a flower can be pollinated by ants, butterflies and bees. Pollination is the transfer of pollen grains from the anthers to the stigma of a flower.

Characteristics of insect-pollinated plants:

They are brightly coloured and have a sweet smell.

They produce a sweet liquid called nectar.

The pollen is heavy and sticky.

They have large petals so that insects can sit on them.

This flower cannot be pollinated by wind because the pollen is heavy and wind-pollinated pollen is very light so, they can fly to distant places.

Overwatered or underwater: Seeds need a minimum amount of water to grow and develop. Nina might have overwatered or underwatered the seeds.
Soil quality: Good soil quality is needed for the development of a seed into a plant as good soil contains all the nutrients needed by the embryo to grow. Nina might have sowed the seed in poor-quality soil.
Low viability: &nbsp;Nina&rsquo;s seeds might have had&nbsp;low viability. When a seed has low viability the chances of it growing into a plant are very less.
