Study Notes

Reproduction in Plants

  • Living things reproduce to create new individuals of the same species, preventing extinction
  • Reproduction is a distinguishing characteristic of living things
  • There are two main types of reproduction in organisms: sexual and asexual
  • Many plants, animals, and simple organisms can reproduce both sexually and asexually
  • Asexual reproduction does not require the fusion of male and female gametes
  • Asexual reproduction produces genetically identical offspring to the parent plant
  • Asexual reproduction occurs through various methods including vegetative propagation, budding, fragmentation, and spore formation

Vegetative Propagation

  • In vegetative propagation, new plants grow from parts of a plant like leaves, stems, or roots
  • Vegetative propagation is a type of asexual reproduction
  • Examples of plants that reproduce by stem include potatoes and ginger
  • Potato tubers have "eyes" which sprout to form new plants

Vegetative Reproduction by Stem

  • Plants like potatoes and ginger can form new plants from their stems
  • Cuttings of stems can grow into new plants (e.g., sugarcane, rose)
  • Planting the cut pieces of potato (containing "eyes") in soil leads to new plants, due to stem modification/tubers
  • These methods commonly used to grow plants, as a simple and efficient way for new plants to sprout

Artificial Methods of Vegetative Reproduction

  • Grafting: Joining a stem cutting (scion) from one plant to the stem of another (stock) promotes growth into one plant
  • A method of growing plants that are difficult to cultivate by other means, or for preserving certain qualities of existing plants
  • Layering: Bending a stem to ground then covering with soil stimulates rooting, allowing the plantlet to grow as a new plant

Advantages of Vegetative Reproduction

  • Fast growth, as it bypasses the need for seeds to germinate
  • Produce more plants from existing plants
  • Suitable for plants that cannot produce viable seeds e.g. bananas
  • Useful for maintaining desirable plant characteristics across generations

Disadvantages of Vegetative Reproduction

  • Offspring are exact copies of the parent, inheriting both desirable and undesirable traits
  • Makes plants susceptible to diseases as they are genetically identical
  • Less genetic diversity in the plant population.
  • Increased vulnerability to diseases and environmental stresses
