With the aid of a well-labelled diagram, show how pollination and fertilization occur in a monocot such as the sugar cane flower.

Here are the solutions to your biology questions.

1. Seed bearing plants

• a) What do you understand by pollination? Pollination is the transfer of pollen grains from the anther (male reproductive part) to the stigma (female receptive part) of a flower. This process is crucial for sexual reproduction in flowering plants, leading to fertilization and subsequent seed formation.

• b) Outline five causes of self-pollination in flowers.

  1. Bisexual flowers: The flower contains both functional male (stamens) and female (pistil) reproductive organs.
  2. Homogamy: The anthers and stigma of the same flower mature simultaneously.
