Well if i am reading the question right then particles of matter are either ions, protons, neutrons or electrons is this have to do with chem or physics bc the question is a little vague
Polyploidy (more than two complete sets of chromosomes) is not rare among plants. For example, pollen grains may reach female flowers via animals or wind. In some cases, pollen grains from species with 4 complete sets of chromosomes will have 2 sets of chromosomes. Pollen grains may fuse with a female reproductive organ with 1 set of chromosome (so, female plant must have 2 sets of chromosomes). The resulting zygote will have 2 + 1 sets of chromosomes, so the plant will have 3 complete sets of chromosomes.
The membrane structures that function in active transport are proteins and lipids. Proteins function in active transport as pumps.
