What is the primary function of chloroplasts in plant cells?
Photosynthesis
Chloroplasts contain chlorophyll that absorbs light energy for the reaction.
Fill in the blank: Photosynthesis uses carbon dioxide and _______ to produce glucose and oxygen.
water
What is the word equation for photosynthesis?
carbon dioxide + water → glucose + oxygen
What is the balanced symbol equation for glucose in photosynthesis?
C6H12O6
In which part of the plant does photosynthesis take place?
chloroplast
True or False: Photosynthesis is a chemical reaction that uses glucose and oxygen to make carbon dioxide and water.
False
True or False: Photosynthesis takes place in the mitochondria.
False
Which part of the plant allows carbon dioxide to enter?
stomata
What is the role of the xylem in plants?
Transport water
True or False: Water travels through the plant in the phloem.
False
What does the plant do with the glucose produced during photosynthesis?
Release energy, use it to produce the cell wall, store it as starch
True or False: The gas produced during photosynthesis is collected in a test tube.
True
Explain what would happen to the number of bubbles if the plant was placed in the dark.
The number of bubbles would decrease.
What happens to the number of bubbles if more carbon dioxide is dissolved in the water?
The number of bubbles would increase.
In an experiment investigating light intensity’s impact on photosynthesis, what are the independent variables?
Light intensity
In the same experiment, what are the dependent variables?
Number of bubbles produced
SKIP
Water temperature, type of plant, carbon dioxide concentration
How could you change light intensity from low to high?
Adjust the distance of the lamp from the plant
What is the function of ribosomes in plant cells?
Protein synthesis
Fill in the blank: The _______ is a structure that surrounds the plant cell.
cell wall
What is the function of the vacuole in a plant cell?
Storage of substances and maintenance of turgor pressure
What is the role of the nucleus in a plant cell?
Control center of the cell, containing genetic material
True or False: Chloroplasts are red.
False
What gas do the bubbles produced during photosynthesis contain?
Oxygen
