I have been raised under an autthoritative parenting style, and my parents were both raised under an authoritarian style (it was more evident in my mother, because my father's mum died when he was 13). I think it was authoritative because they didn't let me do whatever I wanted, but they also didn't keep so much control on me, so I had certain level of freedom, as long as I didn't break anything xD
Matthias Jacob Schleiden was a German botanist who, with Theodor Schwann, cofounded the cell theory. In 1838 Schleiden defined the cell as the basic unit of plant structure, and a year later Schwann defined the cell as the basic unit of animal structure.
