Transcript of Plant rproductuon 2

Sexual and sexual reproduction
There are two types of reproduction - sexual reproduction and asexual reproduction.
Two parents are needed in sexual reproduction, and the offspring produced are genetically different to the parents.
Only one parent is needed in asexual reproduction, and the offspring produced are genetically identical, eg reproduction in bacteria, production of spores by fungi, and the formation of tubers in potatoes and bulbs in daffodils.
why sexual?
These are some of the advantages of sexual reproduction:
introduces variation into a population
the species can adapt to new environments
a disease is less likely to affect all the individuals in a population
These are some of the disadvantages of sexual reproduction:
time and energy are needed to find a mate
not possible for an isolated individual
