Can you explain this? 5% Starch Solution 25% Starch Solution (the purple represents molecules of starch)

What process? What does the arrow represent? osmosis time 5% Starch Solution 25% Starch Solution (the purple represents molecules of starch)

How could you tell which “cell” has the greatest concentration of starch? A B C Each cell has a different concentration of starch solution in it. Tap water is outside each cell.

Which process? Pinocytosis

Which direction (to the inside or to the outside) would molecule move by diffusion?

What specific changes to the cell will most likely occur? protein water K+

Which process? Phagocytosis

Which process?

What processes are occuring at arrows A and B? 90 % water B Active transport A osmosis 100 % water

Why is the contractile vacuole not needed in salt water? X 90 % water 90 % water

Which process?

What life process is happening here?

(neither passive or active transport) Which process? cyclosis The circulation of cytoplasm within certain cells and one-celled organisms. (neither passive or active transport)

neither passive or active transport occurs inside the cell cyclosis neither passive or active transport occurs inside the cell does not involve the cell membrane

Which process? Pinocytosis Phagocytosis

Facilitated diffusion Which process? Facilitated diffusion

What color was the bag in the initial state and the final state? What color was the solution outside the bag in the initial state and the final state? What happened to the size of the bag? Why?

Word Bank amber, blue/black, glucose, iodine, starch, water, white

Which direction would molecule move by active transport? ATP

1. What solution were these cells placed in? 1. Salt solution 2. What process is represented by the arrow? 2. Osmosis 3. What solution could be used to reverse this process? 3. Distilled Water

Label A Cytoplasm Cell Wall Cell Membrane BC

Which process? Exocytosis

Which process? Phagocytosis

In NYS lab, what would the red dots represent? Artificial cell glucose Pore What is the name of this process? Beaker diffusion

diffusion In which direction will the molecules move without energy being applied to them? High Concentration Low Concentration diffusion

When living yeast cells were placed in congo red dye and examined under the microscope, the yeast cells remained colorless. However, when placed in methylene blue, they became blue. Later, dead yeast cells were placed in congo red dye. These cells turned red. Explain these three observations.

A process that would result in the movement of these molecules out of the cell requires the use of 1. diffusion 2. energy 3. osmosis 4. cyclosis

Which process?

Which cell is using energy for the process shown above? Cell A What is the name of this process? Active Transport

In the human body, the potassium ion can pass easily through cell membranes, yet the potassium ion concentration is higher inside many cells than it is outside these cells. This condition is mainly the result of the process of Passive transport Active Transport Osmosis Pinocytosis

In the human body, the potassium ion can pass easily through cell membranes, yet the potassium ion concentration is higher inside many cells than it is outside these cells. This condition is mainly a result of the process of K+ Passive transport Active Transport Osmosis Pinocytosis K+ K+ K+ K+ K+ K+ K+ K+ K+ K+ K+ K+ K+ K+ K+ K+ K+ K+ K+ K+ K+

The change in the appearance off the cell resulted from more… 1. water flowing into the cell than flowing out of the cell 2. water flowing out of the cell than flowing into the cell 3. salt flowing into the cell than flowing out of the cell 4. salt flowing out of the cell than flowing into the cell

What process is this? Active Transport

Is the environment of the cell isotonic, hypotonic, or hypertonic?

1 11 2 3 10 4 9 5 8 7 6

What part of the cell is this? E.R microtubules microfilaments

What organelle is this a part of?

What level of organization is this? tissue

Which process? Facilitated Diffusion

In NYS lab, what would the red dots represent? What is the name of this process? Artificial cell diffusion Pore In NYS lab, what would the red dots represent? Beaker glucose
