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
What cell structure is referred to the powerhouse of the cell and why?
Mitochondria because cellular respiration takes place releasing energy as a product
one produces gas toxic for humans to inhale while the other produces a gas that humans need to survive
cellular respiration and photosynthesis
A solar panel converts sunlight into energy which is stored in a battery. The stored energy is then used to power a light bulb. What kind of energy transformations take place in this entire process?
A. Electrical energy to chemical energy and thermal energy to light energy
B. Chemical energy to electrical energy and solar energy to mechanical energy
C. Kinetic energy to electrical energy and chemical energy to radiant energy
D. Solar energy to electrical energy and electrical energy to light energy
D.
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)
Plant and animal cells vary in a few ways. How does the presence of a cell wall and chloroplasts distinguish plant cells from animal cells?
A. Plant cells lack a cell wall and chloroplasts which animal cells have used for cellular respiration, which are absent in plant cells.
B. Plant cells have a rigid cell wall and chloroplasts used for photosynthesis, which are absent in animal cells.
C. Both plant and animal cells have cell walls and chloroplasts.
D. Animal cells have a cell wall, whereas plant cells have chloroplasts.
B.
How do the locations of photosynthesis and cellular respiration differ within a cell?
Photosynthesis occurs in chloroplasts, while cellular respiration occurs in mitochondria.
Where are protons found in the atom and state their charge
Nucleus, and positive
what are the main products of photosynthesis
glucose and oxygen
What is the most likely explanation for the decrease in glucose and oxygen levels?
A. Muscle cells convert glucose and oxygen into carbon dioxide and water to produce energy.
B. Muscle cells absorb glucose and oxygen from the bloodstream.
C. Muscle cells store glucose and oxygen for later use.
D. Muscle cells release glucose and oxygen as waste products.
A.
Vacuoles can vary in their structure and function. How do these differ between plant and animal cells?
A. Plant cells contain many small vacuoles, while animal cells have a single large vacuole.
B. Animal cells use vacuoles predominantly for energy production, while in plant cells, vacuoles aid in photosynthesis.
C. Plant cells typically have a large central vacuole for storage and maintaining turgor pressure, whereas animal cells have smaller, numerous vacuoles for storage and waste disposal.
D. Vacuoles in plant cells are used exclusively for storing genetic information.
C.
What is the primary functions of photosynthesis and cellular respiration
Photosynthesis produces glucose and oxygen, providing energy, while Cellular respiration breaks down glucose to produce ATP for cellular processes.
Colleen waters the plants in her greenhouse once every day. She wants to find out if the plants will grow more leaves if they are watered more often. She counts the number of leaves on each plant before she starts. She then continues to water half of each type of plant once daily, but she waters the other half of each type twice a day. What is the dependent variable in Colleen’s experiment?
A. The type of plant being grown.
B. The number of leaves the plants grow.
C. The amount of light the plants receive.
D. The number of times the plants are watered.
B.
What is the energy transformation during photosynthesis?
3
In which organelle does cellular respiration take place?
Mitochondria
In both plant and animal cells, this semi-permeable structure surrounds the cell, controlling the passage of substances in and out. What is the name of this structure?
Cell membrane
Every organism needs energy to survive. A process in which oxygen is combined with the breakdown of sugar (glucose) molecules, releasing energy and giving off carbon dioxide and water, is known as which of the following reactions?
1. Cellular repsiration
While sitting in science class, your teacher states that tomorrow you will be completing a lab activity using liquids that are considered alkaline. What type of liquids will you be using?
A. Base
B. Salt
C. Acid
D. Neutral
Base
Two plants were placed in a sealed beaker of water. As time goes on the plant will use up all the carbon dioxide in the water. How will this affect the bubble(gas) formation?
oxygen bubbles will decrease

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
