Study Notes

Vegetative Reproduction

Plants reproduce asexually using vegetative parts
New plants are genetically identical to parent plants
Agriculture and horticulture use methods like cuttings, grafting, tissue culture to propagate plants
Examples of methods :
- Cuttings: a piece of a plant with buds
- Grafting: a portion of a stem (scion) is joined to a rooted plant (stock)
- Tissue culture: growing a small amount of plant tissue

Sexual Reproduction

Fusion of two compatible gametes (sex cells)
Maturity is needed to reproduce sexually
End of the juvenile/vegetative phase signifies the reproductive phase in plants
Flowers are specialized reproductive structures that make haploid gametes
Flower parts: calyx, corolla, androecium, gynoecium
Sexual reproduction involves meiosis and fusion of gametes, producing a diploid zygote and genetically diverse offspring
This is important for species' survival and evolution
Stages in sexual reproduction:
- Pre-fertilization
- Fertilization
- Post-fertilization
