Microscope Lab

This week in biology has been a pretty interesting one. Wednesday we started a new lab about plant and animal cells. During the first part of the lab,that was completed on Wednesday, we had to get  a small piece from an onion and a cilantro plant. We then put those pieces on slides on looked at them through the microscope and sketched what they looked like. Then on Thursday we finished up the lab. One of us in our group had to scrape the inside of their cheek with a toothpick and put it on the slide along with methylene blue. The methylene blue was used so the cells would show up. We also had to sketch what the cheek cells looked like.  

Cell Model Presentation/Enzyme Lab

     This week in biology has been a busy one. We had 2 hour delays Monday and Tuesday which limited  our class time. Our cell model projects were due this week. The presentations started Tuesday but were cut short. Then Wednesday we finished the presentations, but I was absent during that time so I had to present on Thursday. On Friday we finished the enzyme lab that we started the week before. We had to test the different reactions rates with different substances. We used apples, potatoes, and chicken liver. Then we put H2O2 in the test tubes with the differentfoods and recorded their reaction rates. 

                

1st Week of Biology

This past week we were learning about the different types of organic molecules. There are four different organic molecules. Those included: carbohydrates, proteins, lipids, and nucleic acids. Then, we had to work with our table partners to make a graphic organizer on one of those molecules. My table partner and I had proteins. I learned that there are different types of proteins which are enzymes,  hormones, collagen, and hemoglobin. Enzymes speed up chemical reactions. Hormones a substances produced by cells or glands in one part of the body that affects the functions of cells or organs. Collagen is used to form bones, tendons, ligaments and cartilage. Hemoglobin is found in red blood cells of most vertebrates. It transports oxygen to the cells of these organisms.
