Question : 97
Total: 100
The source of oxygen liberated as byproduct during photosynthesis is
carbon dioxide
water
glucose
chlorophyll
Validate
Solution:
The correct answer is
water
.
With the help of
chlorophyll
, plants obtain their nutrients and
water from the soil
, and
sunlight provides solar energy
for photosynthesis.
The proportion of
carbon
in their chemical makeup can
rise on a particularly sunny day
because more photosynthesis occurs.
The
fungus receives sugar
from the plant—made by photosynthesis in the
leaves and transported to the roots
via the plant’s sap.
In places where there is
no sunlight, organisms producing their food
are called
chemotrophs
.
Those in the deep ocean, organisms get the energy from chemicals released by
hydrothermal vents
.
Bacteria can do photosynthesis.
