Photosynthesis
What is the primary pigment in plant cells that captures light energy for photosynthesis?
Chlorophyll
A test tube is filled with water and a green plant called elodea. When the plant is exposed to sunlight, it begins to produce bubbles. What is the most likely conclusion for the identity of the gas in the bubbles, and what process is responsible for producing them?
oxygen
Name one molecule that is both produced during photosynthesis and used during cellular respiration.
Oxygen (O2) or glucose
one produces gas toxic for humans to inhale while the other produces a gas that humans need to survive
cellular respiration and photosynthesis
Why is photosynthesis essential for maintaining oxygen levels on Earth?
Photosynthesis produces oxygen , which is necessary for the respiration of most living organisms
Which gas is taken in by plants during photosynthesis to be used in the process?
Carbon Dioxide (CO2)
Which gas is required for cellular respiration and is a product of photosynthesis?
Oxygen (O2)
where does the energy to start photosynthesis and to cellular respiration come from?
The sun / solar energy
How do the locations of photosynthesis and cellular respiration differ within a cell?
Photosynthesis occurs in chloroplasts, while cellular respiration occurs in mitochondria.
why must cells perform cellular respiration?
It provides cells with the energy they need to function
what are the main products of photosynthesis
glucose and oxygen
what is the equation of cellular respiration?
how are photosynthesis and cellular respiration related?
The products of one process are the reactants of the other.
Compare the primary functions of photosynthesis and cellular respiration in plants.
Photosynthesis produces glucose and oxygen, providing energy, while Cellular respiration breaks down glucose to produce ATP for cellular processes.
Explain how the concepts of photosynthesis and cellular respiration are relevant to agriculture and food production.
Photosynthesis grows the crops, while cellular respiration in plants and animals contributes to growth.
In which organelle does photosynthesis take place in plant cells?
Chloroplasts
In which organelle does cellular respiration take place?
Mitochondria
Organisms digest different foods into glucose. Cells then break down the glucose to provide energy. Which of these substances is also produced during cellular respiration?
Carbon dioxide
what main things do cellular respiration and photosynthesis bring?
Photosynthesis: Carbon dioxide (CO2), water (H2O), light energy. Cellular Respiration: Glucose (C6H12O6), oxygen (O2)
how do humans use the products of photosynthesis?
For energy
what is the equation of photsynthesis?
6CO2 + 6H2O → C6H12O6 + 6O2
Jackson is trying to beat his fastest time running a mile. He finds himself taking long, deep breaths. Which of the statements below apply to Jackson?
A. Jackson’s muscles are undergoing rapid photosynthesis.
B. Jackson’s rate of cellular respiration is increasing to produce more energy.
C. Jackson needs to take in more carbon dioxide to increase energy production.
D. Jackson requires oxygen from air.
B and D
How do both processes contribute to keeping an ecosystem alive?
Both processes are necessary to keep ecosystems alive. Plants create glucose and oxygen which are used in cellular respiration and animals create carbon dioxide and water which are used in photosynthesis.
During photosynthesis, plants take in carbon dioxide, water, and energy from the Sun and produce carbohydrates and oxygen. Which of the following statements best explains how plants follow the law of conservation of mass during photosynthesis?
2
The energy that animals need for their life functions is released when their cells carry out which of the following processes?
4
