they protect the cell from damage
WHEN it works - solar by day, wind when its blowing.
The movement of materials out of the cell by using a vacuole or vesicle is generally referred to as exocytosis.
the advantages are that solar cells use the power of light from the sun, wich is ultimately free. solar cells pay for themselves within a relatively short period of time. In some areas, you can even tap into the local power distribution facility and sell excess electricity your cells produce back into there power grid. Good quality cells may last a very long time. they take up a relatively small amount of space verse wind turbines and water turbines.The disadvantages of solar cells is that they are initially expensive to produce. They are fairly fragile. The only time a solar cell produces electricity is when it is in direct exposure to significant amounts of solar light (during the day time). even though they are thin, they still must take up a significant surface area to receive enough exposure to provide adequate electrical current.
Molecules pass through the plasmodesmata in the cell membrane to get in or get out of the cell. Organelles move around the cell with help of the cytoskeleton - microtubules etc. Substances inside the cell move around with the help of vesicles that come from the Golgi Apparatus or the Endoplasmic Reticulum. sHaYlEn GoVeNdEr.

The advantages of cell phones on human health are the social experience and certain features that may help with health issues. The disadvantages are the distractions from something important, such as driving, and the levels of radiation emitting from the phone.
•The major disadvantages of air-lift fermenters are - high energy requirements - excessive foaming - cell damage due to bubble bursting; particularly with animal cell culture
Advantages are very low emissions. Disadvantage is rarity of hydrogen fuel stations.
Advantages of Daniel cell. 1.it gives a small current for much longer time than the simple cell. 2.polarization does not occur at the copper electrode because of the presence of depolarizer copper (ii)sulphate solution.
Using a satellite phone has many advantages over cell phones. Cell phones require the use of a cell tower which are not available in remote areas. Satellite phones use satellites which are always available as long as you can see the sky.
by mitosis cell can maintain its 2n number , it duplicates without loosing its charecteristics, hence mitosis is the way by which cell maintain its population.
