Table 2 Number of chloroplasts per cell during development.

From: A multiple-method approach reveals a declining amount of chloroplast DNA during development in Arabidopsis

Tissue Chloroplasts per cell Number of cells analyzed
Young 25.6 ± 1.9a 27
Intermediate 39.1 ± 3.3b 34
Mature 48.4 ± 7.5b 17
  1. Young: first and second leaves from 10-day-old plants. Intermediate: first and second leaves from 12-day-old plants. Mature: first and second leaves from 24-day-old plants. Superscript letters indicate means that are significantly different from one another (P < 0.05). Values are means ± standard error.
