Cells in organisms need food, air, and waste removal. how are these needs met? organs and tissues perform these functions for the cells. each cell must specialize in all of these functions. cells get their food from the air and sunlight around them. cells share their waste with other cells.

I believe the correct answer from the choices listed above is the first option. Cells in organisms are able to met the said needs since they have organs and tissues that perform these functions for the cells. 
Hope this answers the question. Have a nice day.

The correct answer would be organs and tissues perform these functions for the cells.

In multi-cellular organisms, similar cells work in integrity to form tissues which in turn form organs.

The organs together form an organ system.

The organ system performs specific functions with the help of specific organs and tissues.

In addition, the organs and tissues help all the associated to get food, air, and remove waste.

For example, blood vessels supply blood to each and every organ and tissue which then ensure that each cell gets food and oxygen.

no it would not be effective against viruses. it'll only kill bacteria.

in case if you get a cold,it may help killing the bacteria which came along with the cold,but it doesn't cure the cold because it is caused by a virus.
