ABSTRACT

The study was conducted to determine and analyze the ability of the Bixa Orellana (atsuete) solution (75%, 50%, and 25%) in distinguishing parts of a human cheek cell and onion cell clearly.

The making of annatto solution is done manually by putting the different concentration annatto 75%, 50%, and 25% on the same container. Different amounts of water (75%, 50%, and 25%) was put in each container. The atsuete was soaked in the water for some minutes until all the color of it was already in the water. It was dropped on the thin piece of an onion and human cheek cell. It was viewed in the microscope and the data were gathered.

Results under the microscope method showed that if 75% of the third solution was used to see the specimen, it is better to use because the parts of the cell has a clearer view in this concentration. While using the second solution, it is not clearer but you can still view the cells of it. And if you use the first solution, you cannot determine well the parts of the cell because it is lighter in color and it is quite visible.

It was concluded that using 75% atsuete and 25% water is the best way in viewing the parts of a human cheek cell and onion cell.
