End of Semester 1 Test

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

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (a sugar) and oxygen.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed for photosynthesis to occur, allowing plants to convert carbon dioxide and water into glucose and oxygen.

Front

What is the chemical equation for photosynthesis?

Back

The chemical equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the importance of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What gas is consumed during photosynthesis?

Back

Carbon dioxide is consumed during photosynthesis.

Front

What is the density formula?

Back

The density formula is D = M/V, where D is density, M is mass, and V is volume.

Front

How do you calculate mass using density and volume?

Back

Mass can be calculated using the formula M = D x V, where D is density and V is volume.

Front

What is the relationship between mass, density, and volume?

Back

Mass is directly proportional to density and volume; if density increases while volume remains constant, mass increases.
