Chemical Reactions

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

Where does photosynthesis take place in plant cells?

Back

Photosynthesis takes place in the chloroplasts of plant cells.

Front

What are the main reactants of photosynthesis?

Back

The main reactants of photosynthesis are carbon dioxide and water.

Front

What is produced as a result of photosynthesis?

Back

The products of photosynthesis are glucose and oxygen.

Front

How does heating affect the rate of a chemical reaction?

Back

Heating usually increases the rate of a chemical reaction, causing the reactants to collide more frequently and with greater energy.

Front

What are some common signs of a chemical change?

Back

Common signs of a chemical change include a change in color, the production of gas (bubbling), and a change in temperature.

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has the same number of each type of atom on both the reactant and product sides, indicating that mass is conserved.

Front

What is the word equation for photosynthesis?

Back

The word equation for photosynthesis is: water + carbon dioxide + energy → glucose + oxygen.

Front

What does it mean if a chemical equation is not balanced?

Back

If a chemical equation is not balanced, it means that the number of atoms for at least one element is not the same on both sides of the equation.

Front

What role do chloroplasts play in photosynthesis?

Back

Chloroplasts contain chlorophyll, which captures light energy needed for photosynthesis.
