Depending on the organism, these needs may include: air, water, nutrients, food, light, shelter, space, certain temperatures, etc. Plants need soil, nutrients, sunlight, water, space, air and appropriate temperatures to survive. Animals need food, water, shelter, oxygen, space and appropriate temperatures.

DNA is the material that makes up a cell's chromosomes and genes. Therefore, without those chemical instructions, RNA couldn't copy the DNA, travel to the ribosome and manufacture necessary proteins. Although the mitochondria are important to carry out respiration in a cell, the nucleus is the most important organelle.

In order to duplicate and segregate correctly, chromosomes must contain three functional elements: (1) origins for initiation of DNA replication; (2) the centromere; and (3) the two ends, or telomeres.
