**Compare and contrast the functions of chloroplasts and mitochondrionCompare and contrast the functions of chloroplasts and mitochondrion
• The cellular machinery requires a continuous energy supply to do all the work of life.
• The two types of cellular power stations are organelles called chloroplasts & mitochondria.
• One harnesses light energy from the sun, and the other "unpacks" this captured energy into smaller packets that are useful for powering cellular work.
Cellular Respiration
• The process by which cells make ATP
Photosynthesis
• Process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and C6H12O6 (glucose or sugar).
ChloroplastsChloroplasts
• Plants and algae (plant-like protists) harness light energy through photosynthesis.
• Found only in Eukarya autotrophs/producers
the sunsugar
ChloroplastsChloroplasts
• Light Energy + water & carbon dioxide Sugars (which are used as chemical energy) & oxygen
• Found only in Eukarya autotrophs or producers
• Two membranes• Fluid filled space
(stroma)• Disk shaped
structures (thylakoids)
• Stack of disks (granum)
• Multiple stacks (grana)

MitochondriaMitochondriasingular: mitochondrionsingular: mitochondrion
• In all eukaryotic cells, mitochondria perform cellular respirationSugar
ATP = energy
MitochondriaMitochondriasingular: mitochondrionsingular: mitochondrion
• Sugar ATP
• (adenosine triphosphate)
ATPATP
• Adenine (blue part)• Ribose (red part)• 3 phosphates (green part)
MitochondriaMitochondriasingular: mitochondrionsingular: mitochondrion
• Double membrane
• Inner membrane has many folds .
MitochondriaMitochondriasingular: mitochondrionsingular: mitochondrion
• Inner membrane also has many enzymes for cellular respiration.
• MATRIX-Inner fluid filled space
Plant cells have both mitochondria and chloroplasts
