Which are the raw materials of photosynthesis? Show Answer
Carbon Dioxide and water Answer for 5 Points Carbon Dioxide and water Back to Board
One sugar produced by photosynthesis is _______. Show Answer
Answer for 5 Points glucose Back to Board
What was the experimental control in the plants and snail lab? Show Answer
Test Tube D containing only bromythmol blue solution only Answer for 5 Points Test Tube D containing only bromythmol blue solution only Back to Board
What is the source of energy used in photosynthesis? Show Answer
Answer for 5 Points Sunlight Back to Board
What is the source of energy used in cellular respiration? Show Answer
Answer for 5 Points Glucose Back to Board
What are two products of photosynthesis? Show Answer
Answer for 10 Points Glucose and Oxygen Back to Board
What is the source of energy for nearly all life on Earth? Show Answer
Answer for 10 Points The Sun Back to Board
What products of cellular respiration are the starting materials for photosynthesis? Show Answer
Carbon Dioxide and Water Answer for 10 Points Carbon Dioxide and Water Back to Board
Photosynthesis takes place in organelles called _________. Show Answer
Answer for 10 Points Chloroplasts Back to Board
What organelle is called the power house of the cell and why? Show Answer
Answer for 10 Points Mitochondria because that is where the 2nd stage of cellular respiration takes place which releases a lot of energy. Back to Board
What is the main purpose of photosynthesis? Show Answer
Answer for 15 Points To make food/glucose Back to Board
What is the main purpose of cellular respiration? Show Answer
To produce energy for cell/life functions Answer for 15 Points To produce energy for cell/life functions Back to Board
The two tubes contain bromthymol blue. The lights are off The two tubes contain bromthymol blue. The lights are off. After 24 hours, what will the color of the water be in tube C? A. Green (it won't change) B. Yellow C. Blue D. Colorless (clear) Show Answer
Answer for 15 Points Correct Answer: B — Yellow Explanation: Plants take in oxygen and release carbon dioxide constantly, just as animals do. They also do the opposite - taking in carbon dioxide and releasing oxygen - through the process of photosynthesis, but ONLY when the lights are on. With the lights off, the Elodea sprigs will be releasing carbon dioxide into the water, which will cause the bromthymol blue solution to turn yellow. Back to Board
What is the difference between an independent and dependent variable What is the difference between an independent and dependent variable? Give an example from the plants and snail gizmo. Show Answer
Answer for 15 Points Independent variable is what the experimenter changes and dependent variable is what the experimenter measures. Example= Changing what is inside the test tubes-plants, snails, number of organisms, or lights on/off is the independent variable. While measuring the carbon dioxide and oxygen levels along with the bromthymol blue solution is the dependent variable. Back to Board
The two tubes contain bromthymol blue The two tubes contain bromthymol blue. After 24 hours, what will the color of the water be in tube B? A. Green (it won't change) B. Yellow C. Blue D. Colorless (clear) Show Answer
Answer for 15 Points Correct Answer: B — Yellow Explanation: The snails will be producing carbon dioxide no matter whether the lights are on or off. Carbon dioxide makes bromthymol blue turn yellow. Back to Board
Describe what occurs during photosynthesis? Show Answer
Answer for 20 Points During photosynthesis, plants absorb energy from the sun and use the energy to convert carbon dioxide and water into sugars and oxygen. Back to Board
Describe what occurs during cellular respiration? Show Answer
Answer for 20 Points During cellular respiration, cells from all organisms break down glucose and other molecules from food in the presence of oxygen, releasing energy. Back to Board
Does your body get all its energy from the sun? Explain. Show Answer
Answer for 20 Points Yes, all of the energy I get comes from the sun. I eat plants which capture light energy from the sun to make food. The energy in animals I eat comes from plants, which in turn get energy from the sun. Back to Board
Could cellular respiration happen without photosynthesis Could cellular respiration happen without photosynthesis? Explain your reasoning. Show Answer
Answer for 20 Points No. The starting materials of cellular respiration are the products of photosynthesis. Without photosynthesis, there wouldn’t be any oxygen or glucose for cellular respiration. Back to Board
Plants cells produce their own food Plants cells produce their own food. They also need energy from the food, which they use for cell activities, growth, and reproduction. What is the name of the process in which plant cells use oxygen to get energy? Show Answer
Answer for 20 Points Cellular Respiration Back to Board
When do cells carry out respiration and why? Show Answer
Answer for 25 Points All the time because cells need a constant supply of energy to carry on all the processes necessary for survival. Back to Board
Why are cellular respiration and photosynthesis opposite processes? Show Answer
Answer for 25 Points Cellular respiration and photosynthesis are opposite processes because the raw materials of photosynthesis are the products of cellular respiration, and the products of photosynthesis are the raw materials of cellular respiration Back to Board
How does the mass of the products of respiration compare with the mass of the reactants? How do you know? Show Answer
Answer for 25 Points The mass of reactants is equal to the mass of the products. Due to conservation of mass the number of atoms of each element does not change, they are only rearranged. Back to Board
What is the chemical equation for Photosynthesis? Show Answer
Answer for 25 Points 6CO2 + 6H2O C6H12O6 + 6O2 Light Energy Back to Board
What is the chemical equation for Cellular Respiration? Show Answer
C6H12O6 + 6O26CO2 + 6H2O + Answer for 25 Points Energy Back to Board
