Semester 1 Final Review

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 chlorophyll in photosynthesis?

Back

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

Front

What is the equation for photosynthesis?

Back

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

Front

What is the significance of sunlight in photosynthesis?

Back

Sunlight provides the energy required for plants to convert carbon dioxide and water into glucose and oxygen during photosynthesis.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable physical characteristics of that organism.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What is the function of stomata in plants?

Back

Stomata are small openings on the surfaces of leaves that allow for gas exchange; they enable carbon dioxide to enter the leaf and oxygen to exit.

Front

What role do bacteria play in the nitrogen cycle?

Back

Bacteria are crucial in the nitrogen cycle as they help convert nitrogen from the atmosphere into forms that plants can use, such as ammonia.

Front

What is the importance of glucose produced in photosynthesis?

Back

Glucose serves as an energy source for plants and is also used to build other organic compounds necessary for growth and development.
