Cell Structure and Function

What is a prokaryotic cell?

• A cell with a nucleus and membrane-bound organelles
• A cell without a nucleus or other membrane-bound organelles
• A cell with only a nucleus and no other organelles
• A cell with no nucleus but membrane-bound organelles

What is a eukaryotic cell?

• A cell with no organelles
• A cell with a true nucleus and membrane-bound organelles.
• A cell with only a nucleus
• A cell without a nucleus

What is cell theory?

• Cell theory is the scientific theory that describes the properties of cells.
• Cell theory is the belief that cells are not the basic unit of life
• Cell theory is the theory that all living things are made of cells
• Cell theory is the study of stars and planets

What are the three parts of cell theory?

• 1. All living organisms are composed of one or more cells. 2. The cell is the basic unit of structure and organization in organisms. 3. All cells come from pre-existing cells.
• 1. All living organisms are composed of two or more cells. 2. The cell is the basic unit of function and organization in organisms. 3. All cells come from non-living matter.
• 1. All living organisms are composed of atoms. 2. The cell is the basic unit of energy and organization in organisms. 3. All cells come from non-living organisms.
• 1. All living organisms are composed of one or more molecules. 2. The cell is the basic unit of structure and organization in non-living matter. 3. All cells come from non-living cells.
