Question

can we write bio practical manual like this in the image(writings in the left and diagrams on right)

Answer 1

Yeah, you can do so as it is one of the most common ways of presenting a biology lab manual.It does not make much difference since all the students follow the norm of drawing a diagram with neat labeling on the blank page and writing in neat and clear handwriting on the roll pages.

Answer 2

yes you can but the most common way is to write on the right and draw diagrams on the left
