  • Mutation- is a permanent change of the nucleotide sequence of the genome of an organism, virus, or extra chromosomal DNA or other genetic elements.
  • Gene flow- the transfer of alleles or genes from one population to another. Migration into or out of a population may be responsible for a marked change in allele frequencies.
  • Nonrandom mating- when the probability that two individuals in a population will mate is not the same for all possible pairs of individuals.
  • Genetic drift- random changes in the frequency of alleles in a gene pool.
  • natural selection-which heritable biological traits become either more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment.


  • stomata- minute aperture structures on plants found typically on the outer leaf skin layer. They consist of two specialized cells, called guard cells that surround a tiny pore called a stoma.
  • roots and roots hair- typically, from the radicleand grows downward into the soil, anchoring the plant and absorbing nutriment and moisture.
  • xylem- compound tissue in vascular plants that helps provide support and that conducts water and nutrients upward from the roots.
  • pholem vascular bundle consisting of sieve tubes.
  • flowers- the reproductive organs and their envelopes if any, especially when such envelopes are more or less conspicuous in form and color.
  • cones -the more or less conical multiple fruit of the pine.
  • meristems-embryonic tissue in plants; growing, actively dividing cells.
  • seeds- the fertilized, matured ovule of a flowering plant, containing an embryo or rudimentary plant.
  • cones-the more or less conical multiple fruit of the pine
