Plant Reproduction
Flowering plants make the next generation through a process that involves pollen, flowers, seeds, and often a helpful animal or a gust of wind. Plant reproduction explains where seeds and fruit come from and why pollinators like bees matter so much. It is a clear, well-defined topic that appears often on tests.
This lesson covers how flowering plants reproduce.
Most plants reproduce using flowers. Pollination is the transfer of pollen from the male part of a flower to the female part. After pollination, fertilization joins pollen and egg to form a seed. Seeds are then dispersed, and each can grow into a new plant.
What are the parts of a flower?
A flower contains the reproductive parts. The male part, the stamen, produces pollen. The female part, the pistil, contains the eggs and a sticky top that catches pollen. Bright petals and scent are not just decoration; they attract pollinators. Understanding these parts makes the rest of the process easy to follow.
How do pollination and fertilization work?
Pollination is the transfer of pollen from a stamen to a pistil. It can happen by wind, water, or animals such as bees, birds, and butterflies that move pollen as they feed. Once pollen reaches the pistil, fertilization occurs: the pollen joins with an egg to form a seed. The surrounding part of the flower often develops into a fruit that protects the seed.
| Step | What happens |
|---|---|
| Pollination | Pollen moves from stamen to pistil |
| Fertilization | Pollen joins egg to form a seed |
| Dispersal | Seeds spread to new places |
How do seeds spread?
A seed that sprouts right under its parent would struggle for light and water, so plants spread their seeds through dispersal. Wind carries lightweight seeds, animals eat fruit and drop the seeds elsewhere, and some seeds float on water or stick to fur. Spreading out gives each seed a better chance to grow. When conditions are right, a seed germinates and begins a new plant.

Garden Tips walks through this skill clearly in a few minutes. It is a helpful companion to the reading above:
A routine for plant reproduction questions
- Identify the flower parts: stamen (male, makes pollen), pistil (female, holds eggs).
- Pollination moves pollen from stamen to pistil.
- Fertilization joins pollen and egg to make a seed.
- Know pollinators (bees, wind) that carry pollen.
- Seeds disperse, then germinate into new plants.
Practice questions
- What is pollination?
- Which flower part produces pollen?
- What forms after fertilization?
- Name two ways seeds are dispersed.
- Why is spreading seeds away from the parent helpful?
- True or false: bees can act as pollinators.
Answers:
- The transfer of pollen from the male part of a flower to the female part.
- The stamen.
- A seed.
- Any two of: wind, animals, water, sticking to fur.
- It reduces competition and gives seeds a better chance for light and water.
- True.
Where this fits
Plant reproduction builds on plant structures and mirrors the sexual reproduction seen in reproduction and variation. Pollinators are part of the relationships in relationships and populations. Find all topics on the ASVAB General Science Learning Hub.
