Identify and explain the functions of the parts of a flower, and describe its pollination type and advantages.

here are the answers to question 4.

a) Name the parts labelled I, II, III, IV, V, VI and VII.

• I: Ovary
• II: Style
• III: Stigma
• IV: Petal
• V: Sepal
• VI: Pedicel (or Flower stalk)
• VII: Filament

b) Give one (1) function each of the parts labelled I, II, III, IV.

• I (Ovary): Contains the ovules which develop into seeds after fertilization, and the ovary itself develops into the fruit.
• II (Style): Connects the stigma to the ovary and provides a pathway for the pollen tube to grow down to the ovules.
• III (Stigma): The receptive tip of the carpel, which receives pollen during pollination.
• IV (Petal): Often brightly colored and scented to attract pollinators like insects.

c) State one (1) type by which the flower is pollinated.
The flower appears to have large, showy petals, which is characteristic of insect pollination.

d) Describe two (2) advantages to the type of pollination stated in (c).

• • Efficiency: Insect pollination is highly efficient because insects actively seek out flowers, ensuring targeted pollen transfer with less waste compared to wind pollination.
• • Genetic diversity: Insects can carry pollen between different plants, promoting cross-pollination which leads to greater genetic variation and stronger offspring.
