respiration in plants Flashcards
What is respiration in plants?
Respiration in plants is the process by which they convert glucose and oxygen into energy, carbon dioxide, and water.
True or False: Respiration occurs only in the presence of light.
False
What are the two main types of respiration in plants?
Aerobic respiration and anaerobic respiration.
Fill in the blank: The main purpose of respiration is to release ________ for cellular activities.
energy
What is the chemical equation for aerobic respiration?
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (ATP)
During which part of the day do plants primarily perform respiration?
Plants perform respiration continuously, both day and night.
What is the role of mitochondria in plant cells?
Mitochondria are the sites of aerobic respiration where ATP is produced.
True or False: Anaerobic respiration produces more energy than aerobic respiration.
False
What is the byproduct of anaerobic respiration in plants?
Ethanol and carbon dioxide.
Which process do plants use to convert glucose into energy during anaerobic conditions?
Fermentation.
Fill in the blank: The process of respiration is crucial for ________ in plants.
growth and development
What is the primary source of energy for respiration in plants?
Glucose.
How does temperature affect the rate of respiration in plants?
Higher temperatures generally increase the rate of respiration up to a certain point before it declines.
What is the significance of oxygen in aerobic respiration?
Oxygen acts as the final electron acceptor in the electron transport chain, allowing for efficient ATP production.
Name one factor that can limit the rate of respiration in plants.
Availability of oxygen.
True or False: Respiration is the same as photosynthesis.
False
What are the end products of aerobic respiration?
Carbon dioxide, water, and ATP.
What is the term for the energy currency produced during respiration?
ATP (Adenosine Triphosphate)
Fill in the blank: The process of ________ involves the breakdown of glucose in the absence of oxygen.
anaerobic respiration
What is one adaptation of plants for respiration in low oxygen conditions?
Some plants can switch to anaerobic respiration to survive.
In which part of the plant does most respiration take place?
In the cells throughout the plant, especially in roots and stems.
How do plants obtain the glucose needed for respiration?
Through photosynthesis, where they convert light energy into chemical energy.
What is the relationship between photosynthesis and respiration in plants?
Photosynthesis produces glucose and oxygen, which are used in respiration to release energy.
What is the role of stomata in the respiration process?
Stomata allow for gas exchange, enabling oxygen to enter and carbon dioxide to exit.
