Mitochondria

ATP synthesis or aerobic/cellular respiration.

Mitochondria (c.)

Contain their own DNA, ability to self-replicate, contain ribosomes similar to bacterial ribosomes.

Chloroplast (c.)

Contain their own DNA, ability to self-replicate, contain ribosomes similar to bacterial/prokaryotic ribosomes.

Nucleus

Contains hereditary information/DNA/chromosomes or is the site of RNA synthesis.

Nucleus (b.)

Hereditary information/DNA/chromosomes or RNA synthesis in cytosol.

Smooth ER (b.)

Lipid synthesis or detoxification occurs in cytosol.

Smooth ER

Lipid synthesis or detoxification or transport.

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

Identify four organelles that should be present in the eukaryotic organism and describe the function of each organelle.

Nucleus, ribosomes, smooth endoplasmic reticulum, mitochondria

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

Mitochondria (b.)

Other membranes or cytosolic molecules function in ATP synthesis.

General Description

Prokaryotic cells have been engulfed by and are living within ancestral/precursor eukaryotes.

Ribosomes

Site of protein synthesis.
