Identify and state the function of the labeled parts of a flower, and describe its pollination type and advantages.

Here are the answers to question 3:

Question 3:

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

• I: Petal
• II: Sepal
• III: Ovary
• IV: Filament
• V: Anther
• VI: Stigma
• VII: Style

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

• I (Petal): Attracts pollinators (e.g., insects) with its color, shape, and scent.
• II (Sepal): Protects the flower bud before it opens.
• III (Ovary): Contains ovules and develops into the fruit after fertilization.
• IV (Filament): Supports the anther to hold it in position for pollen dispersal.
• V (Anther): Produces and contains pollen grains.
• VI (Stigma): Receives pollen during pollination.
• VII (Style): Connects the stigma to the ovary and provides a pathway for pollen tubes.

c) State one (1) type by which the flower is pollinated.

• Insect pollination (or entomophily)

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

• Targeted pollen transfer: Insects can carry pollen directly from one flower to another of the same species, making the process more efficient than wind pollination.
• Less pollen wastage: Because pollen transfer is more targeted, less pollen is needed compared to wind pollination, which relies on chance.
