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

Because plants can’t search out sources of water, they have special adaptations for storing water. This is reflected in the larger size, in plants, of what organelle?

• Nucleus

• Vacuole

• Mitochondria

• Chloroplast

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.
