BiologyChapter 11: Reproduction
Pollination, Fertilisation, Seed — Pollination Types
Self: same flower or same plant.
Learning objectives
- Define pollination types using accurate biology terms.
- Explain why pollination types matters within pollination, fertilisation, seed.
- Apply the learning unit to an FBISE-style example, comparison, diagram, or calculation.
Definition
Self: same flower or same plant. Cross: other plant, more mix. Dichogamy and self-incompatibility named as anti-self tricks. Wind: lots of light pollen. Insect: sticky pollen. Self-pollination: same flower or plant — less variation. Cross-pollination: different plant — more variation. Adaptations: dichogamy, self-incompatibility, showy flowers for insects. This page separates the idea from the wider topic “POLLINATION, FERTILISATION, SEED” so it can be revised and assessed on its own.
Important terms
- POLLINATION TYPES
- Self: same flower or same plant.
- POLLINATION, FERTILISATION, SEED
- Pollination: pollen from anther to stigma (self or cross).
Overview
Study this learning unit in three steps:
Key Idea
Self: same flower or same plant. Cross: other plant, more mix. Dichogamy and self-incompatibility named as anti-self tricks. Wind: lots of light pollen. Insect: sticky pollen. Self-pollination: same flower or plant — less variation. Cross-pollination: different plant — more variation. Adaptations: dichogamy, self-incompatibility, showy flowers for insects.
Examples Anemophily named · Entomophily named · No GM pollen-lab method
Exam Application
Worked double fertilisation: Sperm 1 + egg -> 2n zygote. Sperm 2 + polar nuclei -> 3n endosperm (school). Unique to angiosperms in the syllabus tale.
Examples Anemophily named · Entomophily named · No GM pollen-lab method
WHAT — POLLINATION, FERTILISATION, SEED — POLLINATION TYPES
Self: same flower or same plant. Cross: other plant, more mix. Dichogamy and self-incompatibility named as anti-self tricks. Wind: lots of light pollen. Insect: sticky pollen. Self-pollination: same flower or plant — less variation. Cross-pollination: different plant — more variation. Adaptations: dichogamy, self-incompatibility, showy flowers for insects. This page separates the idea from the wider topic “POLLINATION, FERTILISATION, SEED” so it can be revised and assessed on its own.
WHY — Why this topic matters
POLLINATION, FERTILISATION, SEED — POLLINATION TYPES is an independent FBISE learning unit because students must connect its structures and processes with their biological functions and examples.
HOW — How it works
Self: same flower or same plant. Cross: other plant, more mix. Dichogamy and self-incompatibility named as anti-self tricks. Wind: lots of light pollen. Insect: sticky pollen. Self-pollination: same flower or plant — less variation. Cross-pollination: different plant — more variation. Adaptations: dichogamy, self-incompatibility, showy flowers for insects. Examples: Anemophily named; Entomophily named; No GM pollen-lab method. Exam use: Worked double fertilisation: Sperm 1 + egg -> 2n zygote. Sperm 2 + polar nuclei -> 3n endosperm (school). Unique to angiosperms in the syllabus tale.

Common misconception
- Do not treat pollination types as the same as every other part of pollination, fertilisation, seed; define this unit and use its own evidence, steps, or conditions.
FBISE exam check
- Define pollination, fertilisation, seed — pollination types, explain how it works, and support the answer with one relevant example.
60-second revision
- Self: same flower or same plant.
- Anemophily named
- Exam link: self vs cross.
