A 2 mm plant cell and a 2 mm animal cell are both placed in a beaker of water. At the end of the experiment, the plant cell is 4 mm in size and the animal cell is 6 mm in size. Which cell type was more impacted by Osmosis?
animal cell!
200
What are 2 characteristics of living things?
Movement, need for energy, reproduction, made of cells, maintain homeostasis, growth and development, response to stimulus.
200
Which organelles are only found in plant cells?
Chloroplasts, Cell Wall
200
The sugar plants produce during photosynthesis is ___________.
Glucose
200
Diffusion and Osmosis are controlled by which cell organelle?
Cell membrane
200
Osmosis = water moving from a high concentration to low concentration area through a cell membrane.
A cell biologist was curious about osmosis and the differences between plant and animal cells. She got 1 mm2 sized-samples of cells from an onion and from her cheek and put them in pure water. After the cells soaked for 1 hour in the water, she measured the surface area they covered to answer this investigative question:
Question: What is the effect of type of cells on the amount they expand by osmosis?
What is the controlled variable in this experiment? (stays the same in both groups?)
What is the independent variable in this experiment? (What is being tested, and changes between groups?)
Control= Size of the cells
Independent= type of cell (plant or animal)
300
You used to be a baby, now you are a young adult. What characteristic of living things does this satisfy?
Growth and Development
300
Provide two organelles that both plant and animal cells share, as well as their function
mitochondria- produce energy
nucleus- control center
cell membrane- controls what enters/leaves
vacuole- stores food/water
300
What gas is produced during photosynthesis, and what gas is produced during cell respiration?
P= Oxygen
CR= Carbon Dioxide
300
Which of the following are functions of cells:
A. Use energy
B. Take in Nutrients
C. Get Rid of Wastes
D. Reproduce
All of the above!
300
According to the image, will molecules move into or out of the cell to reach equilibrium?
Into the cell
400
You're too cold, so your body shivers to warm back up. What characteristic of living things does this satisfy?
maintain homeostasis
400
Provide the function of the following organelles:
1. Mitochondria
2. Nucleus
3. Chloroplasts
4. Cell membrane
5. Cytoplasm
6. Lysosome
1. Produce energy
2. Control Center, has DNA
3. Produce glucose, photosynthesis
4. Controls what enters/leaves cell
5. holds organelles in place, jelly-like
6. get rid of wastes, "clean up crew"
400
What are the reactants of cell respiration (What two things go INTO cell respiration?)
Glucose, Oxygen
400
Why do different types of cells (for example, muscle cells and bone cells) look different?
They are from a different part of the body, and have different functions.
400
This type of transport requires energy, and moves molecules from areas of low concentration to high concentration.
A. Passive Transport
B. Active Transport
B. Active Transport
500
A student said that cars can be considered living things because they use energy, move, and age over time. Is the student correct? Provide evidence and reasoning for or against the student's claim.
No- they are not made of cells, and cannot reproduce. Both are essential characteristics of living things.
500
Two students are looking at a sample of cells under the microscope. One student says that they are animal cells, another says that they are plant cells. What organelle could you look for to determine if they are plant cells?
Cell Wall!
500
What are the reactants and products of photosynthesis? What are the reactants and products of cell respiration?
P reactants= carbon dioxide, water, sunlight
P products = glucose, Oxygen
CR reactants = glucose, Oxygen
CR products = carbon dioxide, energy, water
500
From this list, What do prokaryotic and eukaryotic cells BOTH have?
Cell membrane, nucleus, cytoplasm, DNA, ribosomes, membrane bound organelles
ribosomes, cytoplasm, DNA, cell membrane

In a minimum of two sentences, compare Osmosis and Diffusion.
Osmosis is movement of water, diffusion is movement of any other material. Both Osmosis and diffusion occur in cells. Both carry molecules from areas of high to areas of low concentration.
