The presence of which cell organelle would be most helpful in classifying a cell as either prokaryotic or eukaryotic?

• Ribosomes

• Nucleus

• Mitochondria

• Chloroplast

For any activity such as running, jumping and hunting,

animals have to use energy obtained from food. What

organelle performs a similar function within a cell to fuel

cellular activities?

• Nucleus

• Mitochondria

• Vacuole

• Cell membrane

The diagram illustrates some of the organelles found in a cell. Which statement best describes the central organelle indicated by the arrow (#2) in the diagram?

• It is a nucleus and is found in both plant and animal cells.

• It is a cell wall and is found in both plant and animal cells.

• It is a central vacuole and is only found in animal cells.

• It is a mitochondrion and is only found in plant cells

The various parts of a cell, called

organelles, are beneficial to the cell in

what way?

• The parts require nutrients in order

  to work properly.

• The organelles increase the energy

  used by the cell.

• The functions of the cells are

  controlled by genes.

• Each part performs a unique and

  necessary function.

  have died.

• Cell organelles are the smallest

  units of life.

• All cells have the same internal

  structures.

• All living things are made up of

  cells.
