Photosynthesis in Plants Questions
What is the process by which plants make food?
-
Photosynthesis
-
Cellular respiration
-
Transpiration
-
Nitrogen fixation
A
Correct answer
Explanation
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to make food.
Which astrochemical process is responsible for the formation of carbon-based molecules in space?
-
Photodissociation
-
Radiative association
-
Charge transfer
-
Dissociative recombination
C
Correct answer
Explanation
Charge transfer is a process in which an electron is transferred from one atom or molecule to another, resulting in the formation of new chemical species. This process is considered to be a key mechanism for the formation of carbon-based molecules in space.
What is the term used to describe the process by which plants absorb carbon dioxide from the atmosphere and release oxygen during photosynthesis?
-
Carbon sequestration
-
Photosynthesis
-
Respiration
-
Transpiration
B
Correct answer
Explanation
Photosynthesis is the process by which plants absorb carbon dioxide from the atmosphere and release oxygen during photosynthesis.
What is the process by which trees remove carbon dioxide from the atmosphere?
-
Photosynthesis
-
Respiration
-
Transpiration
-
Decomposition
A
Correct answer
Explanation
Photosynthesis is the process by which plants, including trees, use sunlight to convert carbon dioxide and water into glucose and oxygen.
What is the term for the process by which plants absorb carbon dioxide from the atmosphere?
-
Photosynthesis
-
Respiration
-
Transpiration
-
Decomposition
A
Correct answer
Explanation
Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen.
What is the process by which organic molecules are formed from inorganic molecules under conditions similar to those found on early Earth?
-
Abiogenesis
-
Biogenesis
-
Photosynthesis
-
Metabolism
A
Correct answer
Explanation
Abiogenesis is the process by which organic molecules are formed from inorganic molecules under conditions similar to those found on early Earth.
Which process is responsible for the removal of carbon dioxide from the atmosphere by forests?
-
Photosynthesis
-
Cellular respiration
-
Decomposition
-
Transpiration
A
Correct answer
Explanation
During photosynthesis, trees and other plants use sunlight to convert carbon dioxide and water into glucose and oxygen, storing carbon in their tissues.
What is the term used to describe the process by which plants use sunlight, water, and carbon dioxide to produce food?
-
Photosynthesis
-
Cellular respiration
-
Transpiration
-
Nitrogen fixation
A
Correct answer
Explanation
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to produce food. During photosynthesis, plants use the energy from sunlight to convert carbon dioxide and water into glucose, a type of sugar that plants use for energy. Oxygen is also produced as a byproduct of photosynthesis.
What is the term used to describe the process by which plants absorb carbon dioxide from the atmosphere during photosynthesis?
-
Carbon Sequestration
-
Carbon Capture
-
Carbon Storage
-
Carbon Fixation
D
Correct answer
Explanation
Carbon fixation is the process by which plants absorb carbon dioxide from the atmosphere and convert it into organic compounds during photosynthesis.
What is the process by which animals take in oxygen and release carbon dioxide?
-
Respiration
-
Photosynthesis
-
Transpiration
-
Germination
A
Correct answer
Explanation
Respiration is the process by which animals take in oxygen and release carbon dioxide.
What is the process by which plants convert sunlight into energy?
-
Photosynthesis
-
Cellular Respiration
-
Fermentation
-
Glycolysis
A
Correct answer
Explanation
Photosynthesis is the process by which plants convert sunlight into energy, using chlorophyll and carbon dioxide to produce glucose and oxygen.
