Review for Plant Homeostasis and Photosynthesis Test

Front

What are guard cells?

Back

Guard cells are specialized cells that surround stomata and control their opening and closing, regulating gas exchange in plants.

Front

What is capillary action?

Back

Capillary action is the ability of water to move upward through narrow spaces against gravity, often observed in plants as water travels from roots to leaves.

Front

Why are plants called producers?

Back

Plants are called producers because they can make their own food through the process of photosynthesis, converting sunlight into energy.

Front

What is the role of feedback mechanisms in organisms?

Back

Feedback mechanisms help organisms respond to stimuli and maintain homeostasis by returning to normal levels after a change.

Front

How do high temperatures affect photosynthesis?

Back

High temperatures can slow down photosynthesis because they can damage enzymes that are crucial for the process.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What are stomata?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, including the intake of carbon dioxide and the release of oxygen.

Front

What is the significance of chlorophyll in plants?

Back

Chlorophyll is the green pigment in plants that captures sunlight for photosynthesis, allowing plants to convert light energy into chemical energy.

Front

What is transpiration in plants?

Back

Transpiration is the process by which water vapor is released from plant leaves into the atmosphere, helping to regulate water and nutrient uptake.

Front

What factors affect the rate of photosynthesis?

Back

The rate of photosynthesis is affected by light intensity, carbon dioxide concentration, temperature, and the availability of water.
