Pink97 Posted June 10, 2015 Report Share Posted June 10, 2015 The answer is C not D. If the second statement was ''All cells come from pre-existing cells'' then it would be correct. 3 Reply Link to post Share on other sites More sharing options...

a_djoko Posted June 10, 2015 Report Share Posted June 10, 2015 (edited) 2.1.1 Outline the cell theory. The cell theory states that: All living organisms are composed of cells. Multicellular organisms (example: humans) are composed of many cells while unicellular organisms (example: bacteria) are composed of only one cell. Cells are the basic unit of structure in all organisms. Cells are the smallest unit of life. They are the smallest structures capable of surviving on their own.Cells come from pre-exsisting cells and cannot be created from non-living material. For example, new cells arise from cell division and a zygote (the very first cell formed when an organism is produced) arises from the fusion of an egg cell and a sperm cell. IBQuestionBanks answer is C. Edited June 10, 2015 by a_djoko Reply Link to post Share on other sites More sharing options...

ShootingStar16 Posted June 10, 2015 Report Share Posted June 10, 2015 answer's C because not all cells come from pre-existing cells from mitosis. Reply Link to post Share on other sites More sharing options...
