1. How do osmotic power plants work?

2 Research the structures that protect plant and animal cells from damage resulting from osmotic pressure. Write a few paragraphs explaining what they are, how they work, and where they are located.

Expert Solution

Please find the answers below:

Answer 1: The osmotic pressure has a very strong influence on plant. The osmotic pressue is the pressure created by the solvent phase from inside or outside of the cell depending upon the salt concentration against the cell wall. This pressure helps in movement of solvent across the cells and thus maintains a proper water head and water potential across the plant cells. Since this water potential is necessarily involved in controlling rate and extent of absorption of water from roots as well as transpiration from leaves, osmotic pressure thus controls the physiological functions in the plants.

Answer 2: The osmotic pressure is vital, but can be destructive in nature, if uncontrolled. The plant cells bear a protective cell wall around them which holds their structure intact and prevents any collapse or shrinkage taking place due to osmotic pressure disturbance. Similarly, the animal cells contain a semi-permeable cell membrane or plasma membrane around them which protects them from unhostile water disturbances. This membrane assists inwards and outwards movement of water/solvent depending upon the external and internal concentrations.

Thus, these two structures protect the plant and animal cells from osmotic disturbances.

Application of the A&P of the Animal & Plant Cell: Relate the structures of the cell (animal or plant) to parts of some other concrete or abstract structure and explain how each structure connects. Example: Gas to a car is to the mitochondria of the cell. Explanation: Without gas a car would have no means of energy for power to move. Just as the mitochondria "powerhouse" provides energy for the cell. * Whatever structure chosen to compare the cell to...

Comparing plant cells and animal cells Plant cells and animal cells share many of the same structures, but each type of cell also has unique structures.

Part A - Comparing plant cells and animal cells Plant cells and animal cells share many of the same structures, but each type of cell also has unique structures. In this activity, you will indicate which cell structures are found only in plant cells, only in animal cells, or in both plant and animal cells. Drag each cell structure to the appropriate bin. If a structure is found in both plant cells and animal cells, drag it to the "both"...

A power company operates three power generation plants. One is a wind plant, and the other two consume a combination of Fuel 1 and Fuel 2, emitting carbon dioxide in the process. In addition, all three plants require maintenance. The amount of fuel consumed (in Mg), maintenance required (in person-hours), carbon dioxide (CO2) emitted (in Mg), and power generated (in MWh) per day of operation is as follows: Maintenance Fuel 1 Fuel 2 CO2 Power Plant Required Required Required Emitted...
