The main function of the nucleus is

• To make proteins

• Move substances around the cell

• Store DNA - this is the blueprint of life

• Create a vesicle

The main function of the mitochondria is to

• Create energy

• Make proteins

• Move wastes out of the cell

• Create structure for the cell

The definition of a eukaryotic cell is

• A eukaryotic cell has a membrane-bound nucleus and other membrane-bound organelles.
• A eukaryotic cell has a prokaryotic structure.
• A eukaryotic cell has a cell wall and no nucleus.
• A eukaryotic cell has a circular DNA structure.

The eye piece of a light microscope is also known as the

• objective lens
• eyepiece lens
• ocular lens
• magnifying lens

To calculate the magnification of an object (using a microscope) you must

• Divide the magnification of the objective lens by the magnification of the eyepiece lens.
• Subtract the magnification of the objective lens from the magnification of the eyepiece lens.
• Add the magnification of the objective lens to the magnification of the eyepiece lens.
• Multiply the magnification of the objective lens by the magnification of the eyepiece lens.
