Today Mr. Paek was with us. First in class, we talked about the Organelle quiz that we took last friday. The Organelle quiz is total 15 points and there was total 30 questions.

Next, We got our two labs back which was cell structure and function lab and second was diffusion and drawing of cell. Mr. Paek promised us that we'll get our oil spill project scores by thursday. Mr. Paek said if he dosen't get it graded by thirsday he'll give us 5% more of the grade.

Next we went over Enzyme lab our unit packet which was page 24 to page 32 we had to simply start on this during the weekend. Mr. Paek gave us 10 to 15 minutes to graph the individual and group data of enzyme lab.

We had to make sure that
Independent variable is on X-axis
dependent variable on the Y-axis

3 definition that will help you during lab tomorrow



-Crenated is word for animals
-plasmolysed is word for plants
-Plasolysed: meaning when cell shrinks in hypertonic solution

1.Hypertonic solution : more stuff outside the cell so outside stuff tries to come inside like the first picture above so the cell looks like its shrinked . More thing comes in and less thing comes out.

2. Isotonic solution: Cell shape dosen't change. Same ratio of water coming out and same amount going in. The middle one of the picture above. Its just regular size of blood cell.

3.Hyponic solution : more amount exist insides so it trieds to go out so the cell expands. Third picture above the blood cell got bigger. More thing comes out and Less thing comes in.

makes sure you know all these definitions above

OUR HOMEWORK TODAY is to finish the Enzyme lab it is page 24 to 32 of your Unit packet
