A single-celled organism can be classified as a prokaryotic based on the absence of
Cell membrane
Ribosomes
Cytoplasm
Nucleus
Which of the statements below best describes what is taking place in the picture on the left?
The membrane is not permeable to anything and the movement is due to evaporation.
The membrane is permeable to water which allows the particles to move from one side of the membrane to the other.
The membrane is permeable to the particles, but is not permeable to the water. That is why the particles go to one side but the water stays where It is.
The membrane is permeable to water, but is not permeable to the particles. That is why the water goes to one side but the particles stay where they are.
How isit possible that some molecules are allowed to pass through a cell membrane while other molecules cannot?
A cell membrane is found in plant and animals cells
A cell membrane holds organelles in place
A cell membrane is semi-permeable
A cell membrane is surrounded by liquid.
Based off the cell pictures below as seen under a microscope, from which of the following did the specimen most likely come from?
Paramecium/bacteria
Water lily/rose/daisy
Frog/snake/bull
Sponge
One drop of red dye was dropped into a cup of water as seen below. What is causing the dye to "spread out" through the cup?
Diffusion
Osmosis
Photosynthesis
Excocytosis
When would osmosis most likely occur?
Across a non-permeable membrane that separates solutions of different concentrations.
Across a non-permeable membrane that separates solutions of the same concentration.
Across a semi-permeable membrane that separates solutions of different concentrations.
Across a permeable membrane that separates solutions of the same concentration.
What does a plant cell have that an animal cell doesn't?
Ribosomes
Chromosomes
Chloroplasts
Mitochondria
The picture above "H" standard for high concentration and "L" standards for low concentration. What explains what happened to the egg in the first picture (One on left)
The egg will decrease in size due to osmosis
The egg will achieve equilibrium through simple diffusion and remain the same size
The egg will increase in size due to osmosis
The egg will increase in size due to simple diffusion
The before picture is due to a lack of adequate rain fall. The after picture is after placing the plant in a small amount of water. What process caused the plant to become rigid again?
Diffusion
Osmosis
Photosynthesis
Active transport
Using the picture below, identify which is the prokaryotic cell and which is the eukaryotic cell.
The picture on the left:
Prokaryotic
Eaukaryotic
Using the picture below, identify which is the prokaryotic cell and which is the eukaryotic cell.
The picture on the right:
Prokaryotic
Eaukaryotic
Which of the following (left, middle, right) Indicated a plant cell that is in equilibrium and why?
Left: Because water is moving out of the cell which means there is a lower area of concentration on the outside of the cell.
Middle: Because water is moving into and out of the cell meaning the area of water concentration on the outside is the same as on the inside.
Right: Because water is moving into the cell which means there is a lower area of concentration in the cell.
Mitochondria are important in a cell. If the mitochondria stopped working what would happen?
(a)
Which would you find in a plant cell but not an animal cell? (Choose two)
Cell membrane
Cell wall
Chloroplasts
Nucleus
Cytoplasm
If the concentration of molecules on both sides of the membrane are the same during diffusion what will happen?
Molecules would only move to one side of the cell
Molecules would stop moving and stay where they are
Molecules will continue to move back and to keep equilibrium.
What does the nucleus control in a cell?
Maintains energy production
controls the activity of the cell
Stores waste products before they are disposed of.
Stores water and solutions.
What explains what happened to the egg in the second picture (one on right)
The egg will decrease in size due to osmosis
The egg will achieve equilibrium through simple diffusion and remain the same size
The egg will increase in size due to osmosis
The egg will increase in size due to simple diffusion
When put in distilled water, an onion cell will swell up and a red blood cell will burst. Why did the onion cell sweel and the red blood cell burst?
The onion cell is protected by the Chlorophyll
The onion cell is protected by the mitochondria
The onion cell is protected by the cell membrane
The onion cell is protected by the cell wall
Explain why your grandmother was correct when she told you to gargle warm salt water if you had a sore throat.
Draw an arrow on which way the water would flow if following the rules of osmosis,
