9.2-asexual reproduction

• Binary fission is the process by which bacteria divide into two new bacteria.
• Asexual reproduction is when one parent produces offspring with the same genetic makeup as itself
• vegetation is where plants release runners that establish OT systems
• budding is the process of a plant cell creating a daughter trough growth
• budding is where organism beaks into smaller part for form daughter
• parthenogenesis is where embryo develop with no fertilisation.
• binary fission process

  1. replication
  2. attachment
  3. lengthening
  4. division
• longitudinal division

  • nucleus divides by mitosis
  • cytoplasm divides
  • 2 daughter cells formed
• vegetative propagation is where merismatic tissue constantly divide in mitosis for growth
• Runner is stem growth from parent that goes along ground
• cuttings - cloned by taking part of plant and planting it
• rhizomes are underground stems that grow horizontally
• tubers - swollen underground stem from which buds sprout
• bulbs- underground structures that have short steps and a central bud and loosely packed leaves
• Corms- enlarged bulb lie underground stem
• plantlets - tiny young plants that devolp from the meristem.
• fragments on - fragment of organism develops
• budding- organism develops ro division at an outgrowth form parent
• parthenogenesis0 rains made unfertilised
