Organelles
Muscle cells are often required to be in motion and use lots of energy. If you were to look at a muscle cell up close you would most likely see a lot of what organelle?
Mitochondria
Name the three inputs (ingredients) of photosynthesis.
sunlight, water, carbon dioxide.
Explain the difference between passive and active transport.
Active transport requires energy while passive transport does not.
Which of the following is an example of osmosis?
A. Water crossing the cell membrane or cell wall from a higher to a lower concentration
B. Water moving from the large vacuole into the cytoplasm from a lower to higher concentration
You are a doctor attempting to make a diagnosis. You notice a patient's cells have been affected with a disease that shuts off the organelle that controls cellular activities and initiates reproduction. What organelle is this disease most directly damaging?
Nucleus
Prokaryotic cells lack what vital organelle?
nucleus
Name two processes that occur in BOTH plant cells and animal cells.
Draw a diagram explaining diffusion.
lots of dots to a little.
While playing basketball, a student scrapes her knee. Which explanation best describes what organelles work together for her skin to heal after being cut?
A. The chloroplasts provide nutrients for the nucleus to give instructions to the other organelles so that mitosis can occur.
B. The cell membrane controls the amount of energy released so that the lysosomes can give the commands for cellular reproduction.
C. The nucleus gives instructions to start cellular reproduction and the chloroplasts provide ATP for this process.
D. The mitochondria provides the energy for the cell membrane to undergo the process of cellular reproduction.
D
When an analyzing a sample from a patient you notice a buildup of waste in their cells. What organelle is not functioning properly in their cells?
lysosome
List three differences between a plant cell and an animal cell.
Plant cells contain: Chloroplasts, Cell Wall, Large Central Vacuole, No Lysosomes
What is mitosis? Explain the process and what organelles are involved.
Cell division. Nucleus contains DNA on chromosomes that separate to opposite sides of the cell before the cell membrane pinches off and creates two IDENTICAL daughter cells.
Draw a diagram explaining active transport.
a little to a lot, or big molecules. ATP is used.
How do plant and animal cells maintain homeostasis?
A. Both cells obtain nutrients and make food, but only animal cells extract energy by converting sunlight into useable energy
B. Both cells extract energy by converting sunlight into usable energy, but only animal cells obtain nutrients and expel waste from the cell
C. Both cells extract energy through the process of cellular respiration, but only animal cells use lysosomes to expel wastes from the cell.
D. Both cells use energy through the process of cellular respiration and make food through the process of photosynthesis, but only animal cells use lysosomes to process waste
C
You are a scientist looking at the difference between the root cell and leaf cell of a plant. You notice the leaf cell has a significantly larger amount of chloroplasts while the root cell has a higher number of vacuoles. What can you gather about each of these cells?
the root cell plays a bigger role in storage while the leaf cell makes more glucose.
List the three organelles (in order) involved in the production and movement of protein within a cell.
ribosomes make protein, the golgi body packages and ships out protein, it then travels through the ER.
Your teacher throws you a starburst and you eat it. What are the steps taken by your body to get the glucose into your cells, break it down, and then turn it into energy. List the organelles involved.
moved into the cell via the cell membrane (bonus point for active transport), broken down by the lysosomes, turned into energy in the mitochondria via cellular respiration.
Thanks to diffusion, the concentration of many substances...
A. remains higher in the cell
B. remains lower in the cell
C. becomes balanced on both sides of a cell
D. dissappears
C
A student placed a test tube of elodea (an aquatic plant) and pond water 10cm from a light source. He observed that the plant gave off bubbles of a gas and counted how many bubbles were released in one minute. He moved the plant farther away from the light source to see if distance from the source made a difference. The data table below shows his results. What process was occurring and what gas was being released?
Photosynthesis/Oxygen
Dr. Johnson finds a cockroach in his room and decides he wants to keep it as a class pet. He places it in a jar and closes the lid. The next morning he runs through the connecting door in tears, trying to figure out what caused his pet to pass away. Explain to him what he did wrong and what cell process could not take place in his jar.
Lack of oxygen prevented cellular respiration from happening causes his cockroach to transition to the other side.
Name and correctly describe the function of FIVE different cell organelles.
responses will vary.
Explain how food is MADE and then CONVERTED INTO ENERGY in a plant cell. List the organelles involved and the inputs and outputs of each reaction.
Photosynthesis in the chloroplasts (sunlight, CO2, water > glucose, O2). Then mitochondria does cellular respiration (glucose and O2 > energy, water, CO2).
Give an example (small or large scale) of two of our types of transport: diffusion, osmosis, and active transport.
responses will vary.
Which of the following best explains what would happen to animal cells if plant cells did not perform photosynthesis?
A. Animal cells would not be able to process ATP from sunlight.
B. Animal cells would not be able to produce glucose through cellular respiration.
C. Animal cells would not be able to produce oxygen through cellular respiration.
D. Animal cells would not be able to get ATP as a byproduct of cellular respiration.
D
Bromothymol blue (BTB) is a chemical indicator for carbon dioxide (CO2). In the presence of carbon dioxide (CO2), BTB turns from blue to yellow. An aquatic plant was placed into two test tubes containing BTB, and the test tubes were closed with a stopper. Then, one test tube was placed in the dark, and the other test tube was placed in direct sunlight. The test tube in sunlight stayed blue indicating no CO2 was present, while the test tube in the dark changed to yellow. Why did the tube with no light turn yellow?
It performed cellular respiration, adding CO2 to the solution and turning it yellow.
