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
