Verified step by step guidance1
Review the fundamental principles of modern cell theory, which is a unifying concept in biology describing the properties of cells.
Recall that one of the core components of modern cell theory states that all living organisms are composed of one or more cells, emphasizing the cellular basis of life.
Understand that the statement 'All cells contain a cell wall made of cellulose' is incorrect because not all cells have cell walls, and cellulose is specific to plant cell walls.
Recognize that 'The nucleus is the control center of all cells' is not universally true, as prokaryotic cells lack a nucleus.
Note that the idea 'Cells arise spontaneously from nonliving matter' is outdated and was disproven by experiments supporting that cells arise from pre-existing cells.
