Question-

Identify the process shown in the image. What are the characteristics of the flowers shown in this process?​

Answer-

Self-Pollination

Look at points A and B in the illustration below:

This is when pollen from the stamen of a flower is transferred to the stigma of the same flower, or the stigma of another flower from the same plant.

Some plants have male and female parts on different flowers. Others have male and female parts on the same flower. Self-pollination does not result in genetic variation, and therefore the seed from this process is usually not viable or of quality. In some cases, the plant’s biochemical makeup can recognize pollen grains from its flower and abort the process in the event of self-pollination. The scientific name for this is self-incompatibility.

Cross-Pollination

Look at point C in the illustration above:

This is when pollen from one plant is transferred to the stigma of another plant (of the same species). This ensures genetic variety and seeds that result are usually of high quality.

Although possible, it is rare that pollen from one flower—say a coneflower, will fertilize a completely different flower such as a geranium. Sometimes cross-pollination is possible among different plants of the same family.
