Reproduction in plants.
Definition
Plant reproduction occurs through sexual reproduction involving flowers, pollination, and seed formation, or through asexual reproduction where new plants grow from vegetative parts without seeds. In flowering plants, pollen carries sperm to the egg inside the ovule, producing seeds that develop into new plants.
How it works · 6 phases
Step by step.
- Flowers produce pollen (male) in anthers and eggs (female) in ovules.
- Pollination transfers pollen from anther to stigma via wind, water, or animals.
- Pollen germinates on the stigma and grows a pollen tube down to the ovule.
- Fertilization occurs when sperm travels through the pollen tube to fuse with the egg.
- A seed develops from the fertilized ovule, and the ovary becomes a fruit.
- The seed disperses and germinates into a new plant under favorable conditions.
Examples
Real-world.
- 1 Bees pollinating apple blossoms to produce fruit
- 2 Strawberry plants sending out runners to clone themselves asexually
- 3 Dandelion seeds dispersing by wind to colonize new areas
