The actively dividing cells, or meristems, control plant growth. Primary (apical) meristems, the dividing tissue at the tips of the roots, grow longer roots, and secondary meristems, the dividing tissue seen in the cross-sections, grow thicker roots.
        
             
        
        
        
Answer:Each of us has the power, through our own choices and actions, to save American lives and rescue the most vulnerable among us.
That’s why we really have to do what we all know is right.  Every citizen is being called upon to make sacrifices.  Every business is being asked to fulfill its patriotic duty.  Every community is making fundamental changes to how we live, work, and interact each and every day, and I wouldn’t be surprised to see this going on long into the future, when this virus is gone and defeated.  Some of the things we’re doing now will be very good practice for the future, including for not getting the flu, which is very devastating also.  So some of what we’re learning now will live on into the future — I really believe that: shaking hands or not shaking hands; washing hands all the time; staying a little apart.

True
Explanation:
Meiosis is a type of cell division that occurs in gametic cells. In this cell division, one cell is divided into four cells and the chromosome number is reduced to half therefore it is also called reduction division.
During meiosis crossing over occurs between homologous chromosomes that allow the exchange of genetic material between them that results in the formation of genetically unique daughter cells.  
In spermatogenesis during the first meiosis division, the homologous chromosomes get separated into two daughter cells reducing the chromosome number by half and during second meiotic division sister chromatids separate into two more cells. Therefore four genetically different cells are generated.
