Simple organisms may be unicellular, consisting of just one cell, while more complex organisms are multicellular. There are two types of cell division. Mitosis is used for growth and repair and produces diploid cells identical to each other and the parent cell. Meiosis is used for sexual reproduction and produces haploid cells different to each other and the parent cell. Unicellular vs multicellular An ameoba, a simple unicellular organism
Single celled organisms increase their numbers by dividing and making more cells like themselves. Cell Division . When cells are dividing, they grow in size for a bit and then split in two. The cells must make copies of their chromosomes (the information storing part of the cell) before they split. Bacteria only have one chromosome.
