⢠What is the structural and functional unit of living things? In other words, what is considered the basic building block of LIFE?
⢠What three structures are found in the cells of ALL organisms, both prokaryotic and eukaryotic? You may have to look at the pictures of the cells in the Basic Microscopy lab manual content to find all three structures. Note: plasma membrane = cell membrane
⢠List the major differences in prokaryotic cells and eukaryotic cells? Include the location of genetic material in a eukaryotic versus prokaryotic cell.
⢠List the organelles found in a eukaryotic cell that are not found in a prokaryotic cell. You may have to look at the pictures of the cells in the Basic Microscopy lab manual content to find all of these.
⢠In eukaryotic cells, genetic information is found in the form of DNA. Is this true for prokaryotic cells?
⢠Are flagella and cell walls unique to eukaryotes? Why or why not?
