Hey All-Stars, Here is a summary of big ideas of this unit:
-All living things are made of cells.
-There are different types of cells, some more organized (eukaryotic) than others (prokaryotic).
-Cells sustain life, grow, and reproduce and therefore need energy.
-Organelles make up eukaryotic cells and all have different jobs.
-Cells have a membrane that is selectively permeable so the cells can survive without bad stuff getting in or too much good stuff leaving.
-Life on a small scale is studied in microbiology.
-Microbes are microscopic organisms. There are many types, including bacteria, archaea/extremophiles, viruses (non-living!), protists, and fungi.
-Microbes are critical to life - they help digest food, make food, break down dead things, create the atmosphere...
-Microbes that make people sick are called pathogens.
-Disease is studied in epidemiology.
-Infectious diseases are caused by pathogens that can be spread.
-Disease didn't become widespread (epidemics and pandemics) until people moved from hunting/gathering to living in cities w/ animals.
-Vaccines and antibiotics can help stop disease.
-Vectors are organisms that spread, but don't have, disease.
-Biotechnology is useful in all parts of life, but is controversial.
*I will continue to add links, images, and videos to this post to help you study.
Enjoy!
