*Compare and contrast the
functions of chloroplasts
and mitochondria
• 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
CHO
Chloroplasts
• Plants and algae (plant-like
protists) harness light energy
thru photosynthesis
• Found only in Eukarya
autotrophs/producers
Chloroplasts
• Light Energy
• ENERGY
Chemical
Energy
of
Sugars
water & carbon dioxide
• Found only in Eukarya autotrophs or
producers
• Two membranes
• Fluid filled space
(stroma)
• Disk shaped
structures
(thylakoids)
• Stack of disks
(granum)
• Multiple stacks
(grana)
