1,Match the descriptions to the type of transport.

- A. B. C.	Water enters a cell because it is hypertonic compared to the extracellular environment, increasing its turgor pressure
- A. B. C.	Water enters guard cells because the guard cells are hypertonic compared to the surrounding cells
- A. B. C.	Potassium ions are pumped into guard cells
- A. B. C.	The motor cells of a Venus fly trap are hypotonic compared to surrounding cells, causing water to leave the motor cells
- A. B. C.	Sugar is loaded into the phloem

A.	Both active and passive transport
B.	Passive Transport
C.	Active transport

2,Describe what is wrong with the following statement and explain why:

All prokaryotic and eukaryotic cells contain plasma membrane, nucleus, ribosomes, organelles, cytoplasm, and cell walls.

What is short-distance transport?

	a,	The movement of solutes from a region of low concentration to a region of high concentration
		b,The movement of water, nutrients, and other substances between cells
c,		The movement of substances from a region of high concentration to a region of low concentration
d,		The movement of water across a semipermeable membrane from a region of low solute concentration to a region of high solute concentration.

What terms describe the movement of water across a semipermeable membrane from a region of high water concentration towards a region of low water concentration (and high solute concentration.)

What is found in the proptoplasm?

Cell wall, cytoplasm, plasma membrane, nucleus, and other cell organelles

Plasmodesmata, cell wall, and plasma membrane

Cell wall, cytoplasm, and plasma membrane

Cytoplasm, nucleus, and other cell organelles

The channels that allow nutrients and protoplasm to pass between plant cells are called _________________.

What happens when a plant cell is placed in a hypotonic solution?

Water will enter the plant cell and the plasma membrane will swell and cell lysis will occur

Water will leave the plant cell and the plasma membrane will pull away from the cell and plasmolysis will occur

Water will enter the plant cell and the plasma membrane will swell and push against the cell wall

Water will leave the plant cell and the plant cell will lose turgor pressure, causing the plant to wilt

________________ transport uses cellular energy.

What molecules make plasma cell membranes hydrophilic on the outside and hydrophobic on the inside?

What type of cells do plants have?

		Bacterial
		Archaeic
		Eukaryotic
		Prokaryotic

So I learned osmosis and
Marine fish and Freshwater fish

as I know, for the osmosis, water follows higher solute.
For example, when I think about the hypertonic,
I think like this :
because surrounding has higher concentration,
water goes out.

For hypotonic,
because cell(?) has higher concentration than surrounding,
water get into the cell.

But when my lecture was talking about
Fish for Marine and Freshwater, my knowledge was messed up.

the lecture say that fish in freshwater need to maintain a higher ion concentration than surrounding, and they said that the fish in freshwater is hyper osmotic regulator (maintain a hypertonic state)

So what I cannot understand from here is
if fish has more concentration than surrounding,
shouldn't this fish be hypotonic?

why lecture is saying
environment is hypotonic and fish is hypertonic or hyperosmotic regulator????????????

plz explain this on screen
I usually have a really hard time to read with hand writing

Exercise 2: Osmosis

Demonstrating Osmosis with an Artificial Cell Membrane

	Initial Weight	Final Weight	Percent Difference
T= Tube B= Beaker	Group A Group B	Group A Group B	Group A Group B
T= 40% Sugar B= Water			5% 11%
T-20% Sugar			-2.9% -7.4%
T-10% Sugar B- 10% Sugar	40.2 40.2	40.2 40.2	0% 0%
T- Water B-20% Sugar			3.2% 3.6%
T-Water B-40% Sugar			11.04% 9.95%

(Other group of classmates percent difference for artificial cell results)
