sexual vs asexual

• • sexual: The process involving the fusion of the nuclei of two gametes to form a zygote (fertilised egg cell) and the production of offspring that are genetically different from each other
  • asexual: The process resulting in genetically identical offspring being produced from one parent (clones)
• gametes and zygotes

  • gametes have half the chromosomes (1 copy of each - 23) (haploid nucleus)
  • male + female gamete = zygote (46 chromosomes) (diploid nucleus)
• sexual

  A) variation

  B) adapt

  C) advantage

  D) environments

  E) disease

  F) energy

  G) mates

  H) isolated

  I) reproduce

  
• asexual

  A) increased

  B) rapidly

  C) conditions

  D) suitable

  E) efficient

  F) faster

  G) genetic variation

  H) genetically identical

  I) clones

  J) changes

  K) conditions

  L) habitat

  M) disease

  N) whole

  
• label

  A) 1

  B) 2

  C) mitosis

  D) meiosis

  E) identical

  F) parent

  G) unique

  H) mutation

  I) 50

  J) 2

  K) gametes

  L) meiosis

  M) combinations

  N) alleles

  O) chromosomes

  P) assortment

  Q) large

  R) limited

  S) fast

  T) slow

  
• natural asexual in plants 1: runners

  • side branches aka runners that have small plantlets at their ends
  • runners have horizontal stems that grow sideways out of the parent plant
  • once they touch the soil, the plantlets grow roots and the new plantlets will row and become independent from the parent plant

  
• other types of asexual

  A) binary fission

  B) identical

  C) daughter

  D) fragmentation

  E) parent

  F) smaller

  G) regeneration

  H) damaged

  I) missing

  J) budding

  K) organism

  L) bud

  M) vegetative propogation

  N) fragment

  O) parent

  P) sporulation

  Q) diploid

  R) spores

  
• artificial asexual - cuttings

  • a section of the parent plant with a new bud is cut off and placed either into water or soil
  • sometimes the stem of the cutting may be dipped into rooting powder which have hormones
  • cheap and quick
• label

  A) hormone

  B) clone

  C) small

  D) soil
