Identifying flower reproductive structures by position

Steps:

• Locate the male structure at the top of the stamen: this is the anther, which produces pollen.
• Identify the sticky tip of the pistil: this is the stigma, where pollen lands.
• Find the swollen base of the pistil: this is the ovary, protecting developing seeds.
• Spot the small structures inside the ovary: these are ovules, which become seeds after fertilization.

Why A is correct:

• Option A lists structures in standard longitudinal section order: anther (male), stigma (female receptive), ovary (base), ovule (inside ovary), matching typical flower diagrams.

Why the others are wrong:

• B swaps stigma and anther, reversing male-female order.
• C swaps ovule and ovary, placing ovule outside its container.
• D reverses ovary and ovule, ignoring ovule's position within the ovary.

Final answer: A
