Low-power plan diagrams This type of diagram only shows the outlines of the different tissues. It should never show individual cells. Students may be familiar with the specimen (e.g. a cross section of a root or stem) but it is important that they only draw what they can see and not what they think they should see.

What is low power diagram?
Low power drawings The purpose of a low power drawing is usually to show the distribution of the main tissues within an organ, for example in a transverse section of a stem or a trachea. Students are required only to identify the tissues and to delimit the different tissues with boundary lines.
