Reproduction in
flowering plants
, Intro
• Reproduction = the ability of organisms to produce new generations of themse
• Vital for the survival of a species
• Types = asexual and sexual
Asexual Sexual
Production of a new generation from one parent Production of a new generation of same species by bringing tog
genetic material fo 2 parents
One stage…mitosis 2 stages…meiosis
No genetic variation introduced Genetic variation (crossing over & random arrangement)
No gametes Gametes
Occurs in favourable environments…well adapted organisms are In changing environments, species can adapt due to variation
preserved
Fast process Slower process (gamete formation, courtship, gestation, mating
No energy input Large energy input
No outside agents Pollinators
Low chance of evolution High chance of evolution
