Is a cell more complex?
The cell is the most complex and most elegantly designed system man has ever witnessed. … The reason is that organic molecules are so complex that their formation cannot possibly be explained as being coincidental and it is manifestly impossible for an organic cell to have been formed by chance.
What is a complex organism?
A complex organism contains multiple organ systems with different functions. Multiple organisms of a single species may form a group called a population. Many populations of different species form diverse communities and communities that share the same geographical space are part of a larger ecosystem.
How are cells so complex?
To become more complex cells need more genes and more proteins – and so they need to get bigger. … This is a major problem because simple cells generate the energy they need using the membrane that encloses them. Lane and Martin calculate that if a bacterium grew to the size of a complex cell it would run out of juice.
Which cell is more complex plant or animal?

What does a centrosome look like?
Centrosomes are made up of two barrel-shaped clusters of microtubules called “centrioles” and a complex of proteins that help additional microtubules to form. This complex is also known as the microtubule-organizing center (MTOC) since it helps organize the spindle fibers during mitosis.
