Photosynthesis Unit

Photosynthesis & cellular respiration unit test CMS

QuestionAnswer
Series of chemical reactions that convert the energy in food molecules into ATP Cellular Respiration
Considered by biologists to be the energy currency of life. It is the high-energy molecule that stores the energy we need ATP (Adenosine Triphospate)
Pigment which absorbs the sun's energy, gives plants their green color Chlorophyll
Organelle that contains chlorophyll Chloroplasts
The result of carbon dioxide, water, and light energy (product of photosynthesis, provides food and energy for the plant) Glucose
The variable to observe for effects caused by the independent variable. It's the variable that is measured. Dependent variable
Variable in the experiment that changes Independent variable
Variables that are kept the same to keep each test consistent across an investigation Control variable (constant)
Small openings on the underside of leaves that allow gases (carbon dioxide and oxygen) to flow in and out Stomata
Organisms that makes its own food, also known as a producer Autotroph
Organism that cannot make their own food, also known as a consumer Heterotroph
Anything that has mass and takes up space Matter
How is carbon dioxide recycled back into the food chain? Plants undergo photosynthesis where they take in carbon dioxide and convert it into sugar
How do organisms get the energy they need? Plants break down the glucose they produced in photosynthesis, and animals get energy from eating other organisms
Series of chemical reactions that convert light energy, water, and carbon dioxide into glucose and gives off oxygen Photosynthesis
How is cellular respiration different from photosynthesis? Photosynthesis produces oxygen and cellular respiration produces carbon dioxide
What do animals do with the carbon dioxide produced in their cells during cellular respiration? Exhale it in the breathing process
True or false. Oxygen is one product of photosynthesis True
The two products from photosynthesis are oxygen and _________ Glucose
Why is the sun necessary for plants to live on Earth? Plants convert the sun's energy into food
What are the three reactants for photosynthesis? Carbon dioxide, water, energy
What process changes light energy into chemical energy in living organisms? Photosynthesis
Penny writes a word equation to describe photosynthesis, what is that word equation? Carbon dioxide and water combine to produce sugar and oxygen
Which molecule in plant cells first captures the radiant energy from sunlight? Chlorophyll
What are the two products of photosynthesis? Glucose and oxygen
Deforestation (cutting down trees) can _________ the amount of carbon dioxide in the atmosphere. Increase
What are the products of cellular respiration? ATP, carbon dioxide, and water
What are the reactants of cellular respiration? Oxygen and glucose
What are the three functions of the stoma? Breathe in carbon dioxide from the air, release oxygen, release water
During cellular respiration, what happens to the total number of atoms during the chemical reaction? The total number of atoms stays the same.
If sunlight amount goes up, would the rate of photosynthesis increase or decrease? Increase
A HUGE asteroid is thought to have hit Earth near Mexico 65 million years ago which sent up so much dust that it actually blocked the Sun for many years. Because of this, plants were not able to undergo ________ Photosynthesis
The cell process used by both plants and animals to access glucose energy is called __________ Cellular Respiration
What organisms currently on Earth produce oxygen from sunlight? Plants and bacteria
What would happen if photosynthesis did not occur on earth? Every plant and animal would become extinct and the world would be practically deserted
The gas _______ is an input in photosynthesis Carbon dioxide
What is the formula for photosynthesis? Sunlight + Water + Carbon Dioxide → Glucose + Oxygen
What is the main role for cellular respiration? To break down glucose into energy in the form of ATP
What is the flow of energy in a leaf in a swampland? sunlight → chlorophyll → glucose → starch
Is the following describing photosynthesis, cellular respiration, or both: Carbon dioxide is a product Cellular respiration
Is the following describing photosynthesis, cellular respiration, or both: Carbon dioxide is a reactant Photosynthesis
Is the following describing photosynthesis, cellular respiration, or both: Produces a source of energy for an organism Both
Is the following describing photosynthesis, cellular respiration, or both: Chlorophyll is needed Photosynthesis
Is the following describing photosynthesis, cellular respiration, or both: Chlorophyll is not needed Cellular respiration
Is the following describing photosynthesis, cellular respiration, or both: Glucose is a reactant Cellular respiration
Is the following describing photosynthesis, cellular respiration, or both: Glucose is a product Photosynthesis
Is the following describing photosynthesis, cellular respiration, or both: Occurs in the mitochondria Cellular respiration
Is the following describing photosynthesis, cellular respiration, or both: Occurs in the chloroplast Photosynthesis
Is the following describing photosynthesis, cellular respiration, or both: Can be described as a chemical reaction Both
