Plants reproduce through a process called pollination, where pollen from the male reproductive organs (stamen) is transferred to the female reproductive organs (pistil) of a flower. This can occur through wind, insects, birds, or other animals. Once the pollen reaches the pistil, fertilization occurs and a seed is formed. The seed then develops into a new plant through germination.

Sexual Reproduction:
- Pollination: Transfer of pollen grains from the male anther to the female stigma.
- Fertilization: Pollen grain germinates on the stigma, sending down a pollen tube that fertilizes one or two egg cells in the ovary.
- Seed formation: Fertilized egg cell develops into an embryo, which is surrounded by a protective seed coat.
Asexual Reproduction (Vegetative Propagation):
1. Rhizomes, Stolons, and Bulbs:
- Rhizomes: Horizontal underground stems that send out shoots and roots.
- Stolons: Above-ground stems that grow horizontally and produce new plants at their tips.
- Bulbs: Swollen underground stems that store food and water.
2. Cuttings:
- Stems, leaves, or roots are cut from a parent plant and rooted to produce new individuals.
3. Grafting:
- Joining two different plant species by connecting their cut surfaces.
4. Tissue Culture:
- Growing new plants from small pieces of tissue taken from a parent plant.
5. Sporulation:
- Some plants produce spores, which can germinate and grow into new individuals.
