Plates from
Opera Omnia

Figures 1-3

Figures 5-7

The original drawings are lost. The figures here, from Opera Omnia, the fourth edition of Arcana Naturae Microscopiorum, originally titled Anatomia Seu Interiora Rerum.

In the text, Leeuwenhoek indicated that someone else drew the first nine figures.

And when I had them drawn a little larger they appeared as in fig. 2. ABC. ... The reason why I have had these leaves - together with the part from which the root and the stem will come forth drawn so large is to show the leaves with the ribs or vessels, and the dark green round globules which are in the leaves - as indicated here in fig. 3.

He also noted that he had Fig. 14 drawn by someone. If, so then Fig. 13 was probably done by the same person because it seems beyond Leeuwenhoek's skills. However, Nos, 15, 16, and 17 are not, so he probably drew them himself.
