, REPRODUCTION IN FLOWERING PLANTS
REPRODUCTION
• Reproduction is the ability of an organism to produce a new generation of
themselves
• Genes are transferred to next generation during reproduction
• It ensures the survival and evolution of a species
TYPES OF REPRODUCTION
1. ASEXUAL REPRODUCTION:
production of a new generation by
one parent, producing offspring
with identical genetic composition
2. SEXUAL REPRODUCTION:
production of a new generation by
two parents of the same species,
producing offspring which different
genetic composition
ASEXUAL REPRODUTION SEXUAL REPRODUCTION
SIMILARITIES
• Produce the same kind of organism to prevent species becoming extinction (e.g.,
humans making humans)
• Result in the production of food to feed growing world population
DIFFERENCES
One parent Two parents
One stage of mitosis Two stages including meiosis
No gametes formed (sex cells) Gametes formed
Offspring are genetically identical to the Offspring are genetically different to
parent parents
• Results in no genetic variation • Genetic variation exists as genes are
combined
Well adapted individuals are preserved in Individuals with variation can adapt to
stable environments unstable environments
Fast rate of reproduction Slow rate
No energy input therefore more efficient Energy input needed to produce
gametes and for courting therefore less
efficient
No outside agents needed Pollinators necessary
