how would you expect the concentrations of solute inside a plant cell to compare to that of its extracellular fluids? Would you expect the same to be true of the cells of an animal?
Homework Answers
The intracellular concentration of solute inside a plant cell would be expected to be hypertonic when compared to extracellular fluids which causes the cells to gain water and maintain turgor pressure.
The concentration of solute inside animal cells would be expected to be same as that of extracellular fluid so intracellular fluid of it is isotonic solution which would neither cause gain and loss of water.

Of Solute particles. If a cell is in a hypotonic solution, the extracellular fluid has a osmolarity then the inside of the cell. This means it has a solute concentration outside of the cell. Water will move the cell. If a cell is in a hypertonic solution, the extracellular fluid has a osmolarity then the inside of the cell. This means it has a solute concentration outside of the cell. Water will move the cell. If the osmolarity of the...

Question 19 (Mandatory) (2 points) Saved How is plant cell cytokinesis different from animal cell cytokinesis? The contractile filaments found in plant cells are structures composed of carbohydrates; the cleavage furrow in animal cells is composed of contractile proteins. Plant cells deposit vesicles containing cell wall building blocks on the metaphase plate; animal cells form a cleavage furrow. Plant cells divide after metaphase but before anaphase; animal cells divide after anaphase. The structural proteins of plant cells separate the two...

1. Animal cells have a Na,K pump that couples the energy of ATP hydrolysis to transport 3 Na ions out of the cell and 2 K ions into the cell. Inside astrocytes, the concentration of Na is 20 mM and the concentration of K is 130 mM. The extracellular concentrations of Na and K are 145 mM and 5 mM, respectively. Calculate the energy required for the transport of Na and K , with this stoichiometry; assume that the cell...

Describe how a selectively permeable membrane is involved in osmosis. Include the role that the solute concentration plays in the direction of water movement. Now think about how this process may differ between plant and animal cells. For instance, how might cell walls disrupt the role of solute concentration and cause one to refute a hypothesis for the direction of water movement based on water concentration alone?
