Why do cells don't just continue to grow larger as organisms grow larger. why do cells divide

Because an organism needs even more cells to help it function better and change as it grows (like metamorphosis and yes, puberty :p) and if the same amount of cells stay then the organism's cells will be functioning and working harderso cells divide so many different ones can continue to work on different parts of the organism as it grows and changes. Plus it'd be weird if we only had like 1 thousand cells in our body from mothers' pregnancy the size of hi-polymer erasers (the big ones)

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
