Biology learning requires students to carry out observations in practicum activities to form of concept understanding. In the other hand some microscopes had moldy lenses, and the unavailability of practical guidance media that contained photographs of plant tissue observations slashed manually. This development research using tree stages from the 4D development model, namely definition, design and development. The instruments were used interview guides, validity and practicality questionnaires. The validity test results obtained an average value of 3.73. with very valid criteria from the aspects of the appropriateness of content, language and readability, and presentation. Practicality test results obtained an average value of 3.81 with very practical criteria by teachers and 3.65 with very practical criteria by students in terms of learning activities, ease of use, and benefits of use. Based on these, it can be concluded that the Plant Tissues Atlas developed is very valid and very practical. Copyright © 2020 EAI
