Obvious differences occur in nuclear size in those species in which endopolyploidy occurs (Cutter & Feldman 1970b; Dosier & Riopel, 1978), and significant increases in nucleolar size in trichoblasts have also been noted (Lowary & Avers, 1965; Rothwell, 1964; Lewis & Rothwell, 1964).
The number of chloroplasts in guard cells varies with ploidy (auto- including endopolyploidy, or allopolyploidy, without a pertinent difference).
