Abstract
One of the misconceptions can be identified by using CRI (Certainty of Response Index). The purpose of this study was to identify the misconceptions of class XII high school students in the city of Pekanbaru on the material of Photosynthesis and Plant Respiration using the Certainty of Response Index (CRI) method. This research is a survey research. The location of this research was carried out at two high schools in Pekanbaru, namely SMA N 15 Pekanbaru and SMA IT Az-Zuhra Pekanbaru. The number of samples in this study is the total population of the two SMAs. The data collection technique was carried out using a written test instrument in the form of a multiple choice test accompanied by CRI. The average percentage of students' misconceptions of SMA IT AZ-ZUHRA and SMAN 15 Pekanbaru on the concept of photosynthesis, the highest percentage is in the sub-concept of the benefits of photosynthesis for plants by 96.15% and the lowest percentage is in the sub-concept of photosynthetic pigments at 53.19%. The average percentage of students' misconceptions at SMA IT AZ-ZUHRA and SMAN 15 Pekanbaru on the concept of plant respiration, the highest percentage is found in the sub-concept of understanding respiration in plants of 84.62%. The lowest percentage is found in the sub-concept of understanding breathing and the sub-concept of when plants breathe, each of which is 67.58%.

Summary
The setting of standards for the content of basic education is to confirm the urgency of understanding, analyzing, and applying the principles, concepts, and laws of biology to solve real and environmental problems. Biology has a very important role in the development of science and technology. Biology is a branch of natural science that examines scientific conceptions of the life of living things and the interactions between living things. One of the concepts studied in biology is the concept of Photosynthesis and Plant Respiration. This concept is the most important concept in the study in biology because it examines the transfer of energy and matter in an ecosystem. To be able to understand the function of organisms in an ecosystem or biosphere, one must be able to understand the concepts of Photosynthesis and Respiration in Plants well
