Parts of a Plant Cell

1. Cell Wall – The outermost part of a plant cell. It is a hard wall that is made up of many sugars ( polysaccharides). It helps the cell maintain its shape and

it protects the cell.

2. Cell Membrane – Every cell is enclosed by a membrane. The cell

membrane is a double layer of lipids (lipid bi-layer) and is also made of

proteins. The cell membrane allows materials in and out of the cell.

3. Nucleus – (membrane bound) The nucleus contains the DNA and directs

the cell’s activities.

4. Nuclear Envelope - A membrane that surrounds and protects the nucleus.

5. Chromatin - Thin strands in the nucleus that contain genetic material.

6. Nucleolus – This is where the ribosomes are made.

7. Cytoplasm – The cytoplasm is the “soup” inside the cell. The cytoplasm is

made mostly of proteins and water. The cell communicates through the

cytoplasm.

8. Mitochondrion – Converts carbohydrates to energy for the cell.

9. Endoplasmic Reticulum – (membrane bound) It carries material from one part of the cell to another.

10. Rough Endoplasmic Reticulum – This part of the ER contains ribosomes that were made in the nucleolus. This

is the site of protein production.

Page 13: Parts of a Cell 2008

Parts of a Plant Cell

11. Smooth Endoplasmic Reticulum – This part of the ER lacks ribosomes and

is the site of lipid production.

12. Ribosomes – These are found on the RER and throughout the cell.

Ribosomes are factories that assemble proteins.

13. Golgi Body – This receives material from the ER for packaging and

distributes them to other parts of the cell (the mail room).

14. Chloroplasts – Large green structures that contain chlorophyll and

is the site of photosynthesis. They produce food (carbohydrates) for the

cell.

15. Vaculoes – Large storage area in the cell where food, water, and/or waste is

stored.

16. Cytoskeleton – Protein fibers that aid in the internal movement of cell organelles, as well as muscle fiber

contraction.

17. Centrosome – Aids in cell division.

18. Lysosomes – Small round structures that contain chemicals that aid in breaking

down large food particles into smaller particles.
