all offspring in every generation will have the same characteristics of parent plants
Not all Pea plants are true breeding, they can be cross pollinated with another pea plant that has a different genotype. True breeding only means that the traits passed on from the parents are either all dominant or all recessive.
It means they were produce a sexually and werent cloned.
True-breeding means that if they were allowed to self-pollinate, they would produce offspring identical to themselves.
Mendel did indeed use pea plants for his true breeding experiments. Mendel used pea plants because they were easy to breed and showed results very clearly.
True-breeding means that if they were allowed to self-pollinate, they would produce offspring identical to themselves.

all offspring in every generation will have the same characteristics of parent plants
A specific trait. There are true-breeding tall pea plants and true-breeding short pea plants, etc... .
The answer is all of the produced flowers would be Pp
Independently.

When Mendel crossed a true-breeding short plant with a true-breeding tall plant, all the offspring were tall. Which term describes the gene for tallness?

True breeding plants were homozygous for all the characters expressed, hence inheritance of characters was better understood with the help of these plants.
It means they were produce a sexually and werent cloned.
The correct term is "true-breeding". What that means is that if he takes his two pea plants with white flowers and breeds them together, he will always get a pea plant with white flowers. Something that is true-breeding for a particular trait is homozygous, i.e. if the allele for red flowers is R and the allele for white flowers is w, then a true-breeding white flowering plant is ww, and true-breeding red flowering plant is RR. If you cross-breed a true-breeding red flowering with a true-breeding white flowering plant, you would get 1/4 of the offspring as true-breeding red flowers, 1/4 of the off-spring as true-breeding white flowers, and 1/2 the offspring as heterozygous (not true-breeding) red flowers - Rw. If you don't start with true-breeding plants - say you start with Rw and ww (a red and a white plant) you get 1/2 the offspring heterozygous red, and 1/2 true-breeding white. Thus if you didn't know anymore, you would assume that half the time when you breed a red and a white plant, you would get a red plant, and half the time a white, which is incorrect. Furthermore, if you conducted the experiment again, say with RR and Rw, you would get a different result (in this case, all red). By starting with plants that are true-breeding, you ensure that you get the same results that properly show how the traits are passed on.
