'every multicellular organisms has arisen from a single cell'justify this statement
Answers
Answer:
omnis cellula e cellula
Explanation:
we know that all organisms arise from pre existing cells. yes that's the meaning of that statement . If we consider a cell first it grows. but it can grow up to a certain limit. growth is the irreversible increase of drymass. after a certain limit a cell cannot increase its size. then it's starts to divide . this process is considered as cell division. it happens in both asexual and sexual organs by mitosis and meisios respectively. in mitosis one cell grows in interphase and dna replication and duplication of centrosomes takes place and in mitotic phase it produce 2 genetically identical nucleus and in cytokinesis the cell pinches into 2. then these two grows and do the same procedure (cell cycle) and produce 4. by this a single cell grows then divides and produce a whole multicellular organism. meiosis is slightly different here crossing over takes place for sexual cells. here too 4 cells from a single cell produced which are not genetically identical.
