Photosynthesis HW

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 is the role of chloroplasts in photosynthesis?

Back

Chloroplasts are organelles in plant cells that contain chlorophyll, the pigment that captures light energy for photosynthesis.

Front

What is the equation for photosynthesis?

Back

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

Front

What is homeostasis in plants?

Back

Homeostasis in plants refers to the ability to maintain a stable internal environment, such as regulating water loss and gas exchange.

Front

What are guard cells?

Back

Guard cells are specialized cells that surround stomata (pores) in plant leaves and control their opening and closing to regulate gas exchange.

Front

What is autotrophic nutrition?

Back

Autotrophic nutrition is the process by which organisms, such as plants, produce their own food from inorganic substances using light or chemical energy.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is produced as a byproduct of photosynthesis and is essential for the respiration of most living organisms.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is an inorganic molecule that plants take in from the atmosphere and use as a raw material to produce glucose during photosynthesis.

Front

What is a feedback mechanism in plants?

Back

A feedback mechanism in plants is a process that helps regulate physiological functions, such as the opening and closing of stomata by guard cells in response to environmental conditions.

Front

What is the importance of light in photosynthesis?

Back

Light provides the energy required for the photosynthesis process, enabling plants to convert carbon dioxide and water into glucose.
