Unit 6 Review: Cell Energy

Front

What are Guard Cells?

Back

Guard Cells are specialized cells in the epidermis of leaves that control the opening and closing of stomata, regulating water loss and gas exchange.

Front

What is the primary energy source for photosynthesis?

Back

The primary energy source for photosynthesis is sunlight.

Front

Where does cellular respiration occur in a cell?

Back

Cellular respiration occurs in the mitochondria.

Front

What organelle is responsible for photosynthesis in plant cells?

Back

The organelle responsible for photosynthesis in plant cells is the chloroplast.

Front

What processes do plants undergo to produce energy?

Back

Plants undergo both photosynthesis and cellular respiration to produce energy.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

Define cellular respiration.

Back

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

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs sunlight, providing the energy needed for photosynthesis.

Front

What are stomata?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange (oxygen and carbon dioxide) and transpiration (water loss).

Front

What is the equation for photosynthesis?

Back

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