Cellular Energy Exam Review

Front

What is the role of guard cells in plants?

Back

Guard cells regulate the opening and closing of stomata to control water loss and gas exchange, helping maintain homeostasis.

Front

What is the definition of anaerobic bacteria?

Back

Anaerobic bacteria are organisms that can survive and grow in the absence of oxygen.

Front

What happens to sugar production in plants when carbon dioxide is removed?

Back

Sugar production decreases because carbon dioxide is a key reactant in photosynthesis.

Front

What gas do plants release during photosynthesis?

Back

Oxygen (O2) is released as a byproduct of photosynthesis.

Front

What gas do fish extract from water for cellular respiration?

Back

Fish extract oxygen (O2) from water for cellular respiration.

Front

Define photosynthesis.

Back

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

Front

What is cellular respiration?

Back

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

Front

Explain the importance of stomata in plants.

Back

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

Front

What is homeostasis in the context of plants?

Back

Homeostasis in plants refers to the ability to maintain stable internal conditions, such as water balance and gas exchange, despite external environmental changes.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen to produce energy, while anaerobic respiration occurs without oxygen.
