To improve our metabolism. If we were just one big bubble, we would never have enough place on our surface to exchange enough O2, CO2, and the like to be able to live. But if you calculate the surface of the millions of small cells, you'll get a multiple of the surface than that of the big bubble.
if we didnt have cells we wouldnt be alive. cells are a big part in out lives : )

∙ 11y agoFirstly, I assume this refers to multicellular organisms. Multicellular organisms use cells for several reasons; firstly, to increase surface area and thus the organism's durability and capability of intake and expulsion of materials. Moreover, cells are used to differentiate between functions of the organism through their placement in organs.

Why is ATP necessary for the body to function normally?
Adenosine Triphosphate (ATP) provides the energy necessary for the activities of all body cells.
What has everything necessary to carry out life's activities?
Food. Shelter. Water. Love.
Which cellular organelle is required for photosynthesis in eukaryotic cells?
The organelles necessary for photosynthesis in plants are chloroplasts. They hold the chlorophyll that is a necessary part of the process.
Why is ATP necessary for cell nutrition?
ATP allows our cells to maintain, repair and reproduce themselves.
Explain how stem cells are necessary for cell differentiation?
Stem cells are necessary for cellular differentiation because when they divide, they become specialized cells.
Is sugar necessary for growth and division of yeast cells and algae cells?

Why is an replication of DNA essential in al cells?
DNA replication is necessary as cells constantly divide.
How do haploid cells differ from diploid cells?
Haploid cells only have half the necessary amount of DNA (sex cells). Diploid cells have a full set of DNA (body cells).
What is necessary for oxygen transport in red blood cells?
hemoglobin
