PLANT ORGAN SYSTEM AND THEIR FUNCTIONS

Plant Reproduction

• Reproduction is crucial for species survival

• New generations are produced through reproduction

Modes of Reproduction

• Asexual Reproduction:

  • Involves a single parent

  • Offspring are genetically identical to the parent

• Sexual Reproduction:

  • Involves combining genetic material of two organisms

  • Offspring have traits of both parents

Types of Asexual Reproduction in Plants

• KATAKATAKA (Bryophylum):

  • Tiny new plants grow from detached leaves

• Ginger:

  • New plants develop from fleshy underground stems (rhizomes)

• Potato:

  • Bud from potato eye develops into a new plant

• Gabi:

  • Reproduces asexually from corms

• Banana:

  • Produces young shoots from underground stem

• Bermuda Grass:

  • Spreads through stolons or runners

• Roses:

  • Growth from cuttings leads to new plants

• Vegetative Reproduction:

  • New individuals formed without seeds or spores

Types of Asexual Reproduction in Animals

• Fission:

  • Parent cell splits into two identical daughter cells

• Fragmentation:

  • Parent organism breaks into fragments, each developing into a new organism

• Regeneration:

  • Regrowth of lost body parts, often with fragmentation

• Budding:

  • Parent cell forms a bud that develops into a new organism

  AGAMOGENESIS

  Any form of reproduction that does not involve a male gamete.
