Question

which of the following statements is not part of the cell theory? * all cells contain a nucleus. all living things are made up of one or more cells. cells are the basic units of structure and function in living things. all cells come from pre - existing cells. a student places a fresh cucumber slice in a bowl of salty water. after 30 minutes, the cucumber becomes limp and shriveled. what caused this change? salt entered the cucumber cells, causing them to expand.

Explanation:

Cell theory has three main tenets: all living things are made of one or more cells, cells are the basic units of structure and function in living things, and all cells come from pre - existing cells. Prokaryotic cells do not have a nucleus. In the cucumber scenario, water moves out of cells via osmosis when the external environment (salty water) has a higher solute concentration.

Answer:

All cells contain a nucleus.
