ThinkRankReproduction in Plants
Plants reproduce through seeds, spores, and vegetative parts. In flowering plants, pollination allows male and female reproductive cells to meet, after which a fertilised ovule can develop into a seed. Asexual methods produce new plants from one parent and are useful in agriculture.
Learning Objectives
- •Describe sexual reproduction in flowering plants
- •Distinguish pollination from fertilisation
- •Compare seed and vegetative propagation
- •Explain how dispersal helps young plants survive
Key Concepts
Flowers are reproductive structures
Stamens produce pollen, while the pistil includes the stigma, style, and ovary that receives pollen and contains ovules.
Pollination precedes fertilisation
Pollen transfer may occur within a flower or between flowers; fertilisation occurs when male and female cells fuse.
Dispersal reduces competition
Wind, water, animals, and explosive fruit actions spread seeds away from the parent plant.
Terminology
Historical Insight
Cutting
Rose, sugarcane, and some other plants can grow from stem cuttings under suitable conditions.
Seed dispersal
Hooks, wings, fleshy fruits, and light seeds show how plant structures aid different dispersal methods.
