Mandel used pure lines in his experiment to ensure that the light sources had well-defined and narrow spectral characteristics, which is crucial for studying quantum interference effects. By using pure lines, he could minimize the impact of spectral broadening and ensure coherence in the light, allowing for a clearer observation of phenomena such as the Hong-Ou-Mandel effect. This approach helped in demonstrating the fundamental principles of quantum optics and the behavior of photons in a controlled manner.
Mendel used all tall plants in his F1 experiment because that was the offspring from his cross of a pure tall plant and a pure short plant. By crossing two of the tall plants from F1, he proved that the recessive gene (t) was still present in the F1 generation, despite the phenotypes of all of these plants being tall. (The result of the F1 cross gave 3 tall plants and 1 short plant.)

Mendel used pea plants in his experiment because they have distinct traits that are easy to observe and manipulate. Pea plants also have a relatively short life cycle which allowed Mendel to conduct multiple generations of controlled breeding experiments. This made it an ideal model organism for studying inheritance patterns.
