1.Cell Membrane- the outermost living structure of a cell. a.It controls the passage of materials into and out of the cell.

2.Vacuole- liquid-filled sacs that store materials that the cell has taken in or produced.

3.Nuclear Membrane – the outermost part of the nucleus.

4.Cytoplasm – the material in the cell that surrounds the nucleus. It carries out most of the activities in the cell.

5.Cell wall – it is a rigid material, that is nonliving. It protects all of the living parts of the __plant cell __.

6.Chloroplasts- small green bodies; where photosynthesis occurs.

7.Nucleolus- a round body containing protein. It sends messages to the cytoplasm.

8.Chromatin- made up of very fine coiled threads. Before cell division and reproduction – they shorten and thicken into rods called Chromosomes.

9.Mitochondrion- oblong structure scattered in the cytoplasm. They produce energy for the cell. Sometimes called the Powerhouse of the cell.

10.Nucleus- round body near the middle of the cell; contains genes, which control all cell activity.

11.Centriole- a pair of small organelles near the nucleus. They assist in cell division.
