Explanation:
new cells rather than growing bigger. Why is this ?
There are two main reasons why cells divide rather than continuing to grow larger and larger: ... If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. Cell Division. Cell division is the process by which cellular material is divided between two new daughter cells.
Why aren't you made of a few dozen, or a
few hundred cells, instead of trillions?
 if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.
Why don't single-celled organisms like amoebas and paramecia grow
as big as a human?     again The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.

The series explores strategies to sustainably feed more than 9 billion people by 2050. All pieces are based on research being conducted for the 2013-2014 World Resources Report. The world is projected to hold a whopping 9.6 billion people by 2050.
        
                    
             
        
        
        
Science isn't just gathering factual information and data, it's a body of knowledge. It's a way of thinking about problems, and how to solve them. Science shapes everything in our world since everything revolves around natural rules.
It's thanks to computer <em>science </em>that you're able to be on this site right now. It's thanks to <em>science </em>as a whole that we have any of the technology we have today, and the cures for the many once <em>deadly </em>diseases. So, if you want to know how science shapes our world... Just look around you. =)

<h2>Type of Organisam to a Characteristic </h2>
The chloroplast produces food from inorganic materials. Anaerobic organelles cannot survive in the presence of oxygen this is because oxygen does not help in it's growth. Though eukaryotic cells contain cell nucleus. This is why chloroplasts produce food through photosynthesis.
