Model Answer
Diagram:
```
Stigma ← pollen grain lands here
|
Style
|
Ovary
(contains ovule with egg cell)
Pollen tube grows from pollen grain → travels through style → reaches ovary
```
(Draw a neat labelled diagram showing a pistil with a pollen grain on stigma, pollen tube growing down through the style into the ovary.)
(a) The part that receives the pollen grain is the Stigma (the sticky terminal part of the pistil).
(b) The Pollen tube grows out of the pollen grain and travels through the style to carry the male germ cell to the female germ cell in the ovary.

Explanation
- The diagram must show: pollen grain on stigma → pollen tube → style → ovary. Label only the two asked parts: Stigma and Pollen tube.
- (a) Stigma is the correct term; do not write "style" or "pistil."
- (b) Pollen tube is the key term here — it is not the pollen grain itself that moves, but a tube that grows out of it.
- Since it's 2 marks, one mark each for correctly naming and labelling the two parts (the diagram supports both). Keep the diagram simple but neat.
