What are the differences between chloroplasts and mitochondria?

Posted March 27, 2023


Answer

Basis of differentiation

Chloroplasts

Mitochondria 

Location

Chloroplasts are found in plant and algae cells

Mitochondria are found in all eukaryotic cells 

 

Color

Typically green in color

Typically colorless 

Shape

Disc-like shape

Bean-like shape

Presence of pigments

Chlorophyll and carotenoids exist as photosynthetic pigments

No pigments exist in mitochondria

Foldings

Foldings in inner membrane form stromules

Foldings in inner membrane form cristae

Compartment location

Its two compartments are: stroma and thylakoids

Its two components are: the matrix and cristae

Energy source

Store solar energy in the chemical bonds of glucose

Convert sugar into chemical sugar which is ATP

Glucose involvement

Use carbon dioxide and water to build glucose molecules (Calvin cycle)

Breaks down glucose into water and carbon dioxide (glycolysis) 

Functions

Are sites for photosynthesis and photorespiration

Are sites for oxidative phosphorylation, beta-oxidation, and photorespiration 

Size

Are 5-7 micrometers in diameter

Are 0.5-10 micrometers in diameter

Molecules formed

ATP and NADH are formed

ATP are formed
