Summary:
The nourishment that the plant receives from the ground by an עציץ נקוב is greater than the nourishment it receives from the ground through its branches.
And do they not argue when it took root; but be learnt, ‘two gardens, etc.' -ובדאשרוש לא פליגי והתנן שתי גנות כולי
Summary:
Initially we assumed that the basis of the מחלוקת between ר"מ ור"י (is not who can destroy the plant, but rather it) is whether we follow the root or the plant.
Summary:
קלף is not mentioned either because it is not considered ‘hide’ anymore (רש"י), or because its שיעור was already explicitly mentioned in a משנה elsewhere ('תוס).

Summary:
A woman must bring ע"מ (according to ר"א), only if it is a כתב שיכול להזדייף, otherwise we can rely on the ע"ח. According to ר"מ even if she brings עדים that nothing was changed it is not effective since it is not מוכח מתוכו (רש"י seems to disagree).
