Summary: Any proposed mechanism for organelle size control should be able to account not only for average size but also for the variation in size. We analyzed cell-to-cell variation and within-cell variation of length for the two flagella in Chlamydomonas. finding that cell-to-cell variation is dominated by cell size. whereas within-cell variation results from dynamic fluctuations. https://www.jalyttlers.shop/product-category/flat-cap/
