Question

Known as the “Pine Tree State,” Maine's state tree is the Eastern white pine. Consider the model. Carbon dioxide, water, and sunlight are reactants of photosynthesis and are used to produce glucose and release water as a byproduct. What advantage does the pine tree have in performing photosynthesis compared to deciduous trees such as oak or maple?
Responses
A Pine trees need less water to do photosynthesis.Pine trees need less water to do photosynthesis.
B Pine trees produce twice as much glucose as deciduous trees.Pine trees produce twice as much glucose as deciduous trees.
C Pine trees do not lose their leaves and can photosynthesize all year.
Pine trees do not lose their leaves and can photosynthesize all year.
D Pine trees get more sunlight than oak trees due to their darker color.

Answer 1

C — Pine trees do not lose their leaves and can photosynthesize all year. Their needlelike leaves persist through winter, allowing photosynthesis whenever temperatures and light permit, unlike deciduous trees that drop leaves in autumn.
