Answer:
1. Are usually single-celled.
2. Do not contain membrane-bound organelles
3. Have DNA located in cytoplasm
Explanation:
Prokaryotic cells are single-celled organisms which have the following characters:
1. They lack a true nucleus and hence, they do not have their genetic material enclosed in a nuclear membrane-bound nucleus, rather it is present in the cytoplasm.
2. They lack all the membrane-bound organelles such as mitochondria, endoplasmic reticulum, etc.
3. They are usually. very small in size and hence are microscopic. 
 Examples include all the bacterias. 
 
        
                    
             
        
        
        
 
<span>The genotype is
required for you to use a punnet square. In the construction of a punnet's
square, the genotypes of both parents are required. In the three by three
square, the first column shows the genetic representation of one parent and the
first row shows the genotype of the other parent. The two are combined, and
they yield a genetic combination of both parents, giving all the possible
outcomes of the offspring's genotypes. Using the punnet's square, you can be
able to identify the percentage of the offspring that will be heterozygous or
homozygous.</span>
