BiologyChapter 11: Reproduction
Pollination, Fertilisation, Seed — Seed and Fruit
Endosperm feeds the embryo (cereal).
Learning objectives
- Define seed and fruit using accurate biology terms.
- Explain why seed and fruit matters within pollination, fertilisation, seed.
- Apply the learning unit to an FBISE-style example, comparison, diagram, or calculation.
Definition
Endosperm feeds the embryo (cereal). Cotyledons in beans. Dormancy: wait. Scarify/cold named as nature cues, not a warehouse process. False fruit (apple) if the book asks. Seed = embryo + endosperm/cotyledon store + testa (seed coat). Fruit develops from ovary wall. Dispersal: wind (dandelion), animal (berry), explosive (pea pod). This page separates the idea from the wider topic “POLLINATION, FERTILISATION, SEED” so it can be revised and assessed on its own.
Mathematical form
Seed = embryo + endosperm/cotyledon store + tes
fruit = ovary
Important terms
- SEED AND FRUIT
- Endosperm feeds the embryo (cereal).
- POLLINATION, FERTILISATION, SEED
- Pollination: pollen from anther to stigma (self or cross).
Overview
Study this learning unit in three steps:
Key Idea
Endosperm feeds the embryo (cereal). Cotyledons in beans. Dormancy: wait. Scarify/cold named as nature cues, not a warehouse process. False fruit (apple) if the book asks. Seed = embryo + endosperm/cotyledon store + testa (seed coat). Fruit develops from ovary wall. Dispersal: wind (dandelion), animal (berry), explosive (pea pod).
Examples True fruit = ovary · Dispersal away from parent · Germination needs water + O2 + T
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 True fruit = ovary · Dispersal away from parent · Germination needs water + O2 + T
WHAT — POLLINATION, FERTILISATION, SEED — SEED AND FRUIT
Endosperm feeds the embryo (cereal). Cotyledons in beans. Dormancy: wait. Scarify/cold named as nature cues, not a warehouse process. False fruit (apple) if the book asks.

WHY — Why this topic matters
POLLINATION, FERTILISATION, SEED — SEED AND FRUIT is an independent FBISE learning unit because students must connect its structures and processes with their biological functions and examples.
HOW — How it works

Core idea
- Endosperm feeds the embryo (cereal). Cotyledons in beans. Dormancy: wait. Scarify/cold named as nature cues, not a warehouse process. False fruit (apple) if the book asks. Seed = embryo + endosperm/cotyledon store + testa (seed coat). Fruit develops from ovary wall. Dispersal: wind (dandelion), animal (berry), explosive (pea pod). This page separates the idea from the wider topic “POLLINATION, FERTILISATION, SEED” so it can be revised and assessed on its own.

Common misconception
- Do not treat seed and fruit 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 — seed and fruit, explain how it works, and support the answer with one relevant example.
60-second revision
- Endosperm feeds the embryo (cereal).
- True fruit = ovary
- Exam link: embryo + store + coat.
