During an investigation of a freshwater lake, an AP Biology student discovers a previously unknown microscopic organism. Further study shows that the unicellular organism is eukaryotic. (a) Identify FOUR organelles that should be present in the eukaryotic organism and describe the function of each organelle.

Nucleus-Contains hereditary information/DNA/chromosomes or is the site of RNA synthesis. Ribosomes-Site of protein synthesis. ER-Internal transport or compartmentalization. Rough ER-Protein synthesis/packaging/transport. Smooth ER-Lipid synthesis or detoxification or transport. Mitochondria-ATP synthesis or aerobic/cellular respiration. Chloroplasts, plastids-Light absorption/photosynthesis/carbohydrate synthesis. Vacuole, vesicles-Storage or transport. Cilia/flagella-Motility. Basal bodies-Support cilia/flagella. Centrioles-Assist chromosome movement in mitosis. Golgi bodies-Protein modification/packaging/transport. Lysosomes-Enzymatic hydrolysis of wastes/metabolites/pathogens. Peroxisomes-Catalase/peroxidase function or detoxification. More test answers on https://studyhippo.com/ap-bio-essay/

What is AP Biology?

AP Biology is an exciting and challenging course designed to provide students with a comprehensive overview of the biological sciences. This college-level course covers topics such as genetics, evolution, ecology, cell biology, physiology, biochemistry and molecular biology. Additionally, it also provides an introduction to laboratory skills and techniques used in modern scientific research. For many students taking AP Biology can open up new avenues for higher education opportunities in science or medicine related fields. During the course they gain invaluable experience that will benefit them when applying to universities or colleges. Furthermore the knowledge obtained during the class will give them an advantage on university entrance exams such as the MCAT or GRE. The curriculum for AP Biology includes foundational topics like cellular processes; energy transformation; genetic information transfer & expression; gene regulation & DNA replication; evolution & natural selection; organismal structure/function relationship; ecology concepts & population dynamics; evolutionary relationships among organisms and species diversity. In addition there are also advanced modules which cover more intricate aspects of these topics including lab based investigations into DNA manipulation techniques and statistical data analysis. The format of this course encourages independent learning as well as active participation within group activities/labs in order to fully understand all content areas covered during class time. It’s also important for students to stay current with any relevant news articles about recent discoveries made in science so that they can discuss their implications with their peers during class discussions and projects assigned by teachers throughout the year. In conclusion AP Biology offers a unique opportunity for high schoolers who wish to pursue further studies after graduation in any field relating to life sciences (medicine, veterinary medicine etc). The subject matter taught is highly specific yet incredibly broad at same time allowing one to become knowledgeable about various aspects related life sciences quickly but efficiently over time through extensive studying supported by both laboratory experiments as well as written assignments such us essays/reports etc.
