AP Biology cell frq Questions and Answers
Identify four organelles that should be present in the eukaryotic organism and describe the function of
each organelle. - ✅✅Nucleus, ribosomes, smooth endoplasmic reticulum, mitochondria
Nucleus - ✅✅Contains hereditary information/DNA/chromosomes or is the site of RNA synthesis.
Ribosomes - ✅✅Site of protein synthesis.
Smooth ER - ✅✅Lipid synthesis or detoxification or transport.
Mitochondria - ✅✅ATP synthesis or aerobic/cellular respiration.
Prokaryotic cells lack membrane-bound organelles found in eukaryotes. However, prokaryotes must
perform many of the same functions as eukaryotes. For three of the organelles identified in part (a),
explain how prokaryotic cells carry out the associated functions. - ✅✅Nucleus, smooth er,
mitochondria
Nucleus (b.) - ✅✅Hereditary information/DNA/chromosomes or RNA synthesis in cytosol.
Smooth ER (b.) - ✅✅Lipid synthesis or detoxification occurs in cytosol.
Mitochondria (b.) - ✅✅Other membranes or cytosolic molecules function in ATP synthesis.
According to the endosymbiotic theory, some organelles are believed to have evolved through a
symbiotic relationship between eukaryotic and prokaryotic cells. Describe three observations that
support the endosymbiotic theory. - ✅✅Mitochondria, Chloroplast, general description
General Description - ✅✅Prokaryotic cells have been engulfed by and are living within
ancestral/precursor eukaryotes.
