Why is DNA replication important for growth & repair in multicellular organisms?

• to ensure that the organism’s genetic information is passed on to every new cell.

• to ensure that every new cell gets half an organism’s genetic information.

• to ensure that the genetic information is passed down to an organism’s offspring.

• to ensure that life goes on after death.

• active transport using ATP and carrier proteins

• passive transport by osmosis

• phagocytosis

In 1838, scientists Matthias Schleiden and Theodor Schwann formulated an early version of the cell theory, stating that all organisms are made of cells and that the cell is the basic unit of life. Which statement best completes the modern cell theory?

• Cells contain hereditary information that can be passed on.

• Cells of different organisms have different chemical compositions.

• Cells have more than one origin.

• Cells are independent organisms.

• All cells come from pre-existing cells.

• Some cells can be instructed to be any type of cell.

• All living organisms are composed of one or more cells.

• The cell is the basic unit of structure, function and organization in all living organisms.
