The reactants of photosynthesis are
glucose and water.
glucose and oxygen.
carbon dioxide and water.
carbon dioxide and oxygen.
Plants get the energy they need for photosynthesis from
water.
soil.
sunlight.
oxygen.
What are the products of photosynthesis?
carbon dioxide and water
glucose and water
glucose and oxygen
carbon dioxide and oxygen
What pigment absorbs sunlight during photosynthesis?
chloroplast
thylakoid
grana
chlorophyll
What is the correct equation for photosynthesis?
6CO2 + 6H2O --> 6O2 + C6H12O6
6CO2 + C6H12O6 + 6H2O --> O2
6O2 + 6H2O --> 6CO2 + C6H12O6
C6H12O6+ 6O2 ---> 6H2O + 6CO2
Which gas is removed from the atmosphere during photosynthesis?
water vapor
oxygen
nitrogen
carbon dioxide
What is the primary function of the light-dependent reactions of photosynthesis?
To produce glucose
To split water and generate usable energy in the form of ATP
To use ATP
To fix gaseous CO2 into glucose
Within the chloroplast, where do the light dependent reactions occur?
thylakoid membrane
stroma
mesophyll
mitochondria
Plants need carbon dioxide from their environment to produce glucose during which stage of photosynthesis?
The light-dependent stage on the thylakoids
The light-independent stage in the stroma
The light-dependent stage in the stroma
The light-independent stage on the thylakoids
From which molecule does a plant get most of its mass?
carbon dioxide
water
sunlight
soil/nutrients
What is released as a byproduct during the light dependent reactions?
water
oxygen
glucose
carbon dioxide
Leaf disks in the leaf disk lab floated because
CO2 gas was released into the spaces in the leaf making them lighter
Leaf disks only float when they stop performing photosynthesis
O2 gas was released into the spaces in the leaf making them more buoyant and causing them to float
Glucose is stored in the spaces in the leaf, making them float
How does water enter root cells from the soil?
capillary action
osmosis
both osmosis and capillary action
transpiration
How does water travel up xylem tubes to reach the leaves?
capillary action
osmosis
both capillary action and osmosis
photosynthesis
How does water leave plants?
Pores in roots called stomata
Pores in leaves called stomata
Water doesn't leave; it automatically gets reused.
Water doesn't leave; it gets stored within the plant.
