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.
Parts of a Plant 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.
Parts of a Plant Cell
3. Nucleus – (membrane bound) The nucleus contains the DNA and directs
the cell’s activities.
Parts of a Plant Cell
4. Nuclear Envelope - A membrane that surrounds and protects the nucleus.
Parts of a Plant Cell
5. Chromatin - Thin strands in the nucleus that contain genetic material.
Parts of a Plant Cell
6. Nucleolus – This is where the ribosomes are made.
Parts of a Plant Cell
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.
Parts of a Plant Cell
8. Mitochondrion – Converts carbohydrates to energy for the cell.
Parts of a Plant Cell
9. Endoplasmic Reticulum – (membrane bound) It carries material from one part of the cell to another.
Parts of a Plant Cell
10. Rough Endoplasmic Reticulum – This part of the ER contains ribosomes that were made in the nucleolus. This
is the site of protein production.
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.
Parts of a Plant Cell
13. Golgi Body – This receives material from the ER for packaging and
distributes them to other parts of the cell (the mail room).
Parts of a Plant Cell
14. Chloroplasts – Large green structures that contain chlorophyll and
is the site of photosynthesis. They produce food (carbohydrates) for the
cell.
Parts of a Plant Cell
15. Vaculoes – Large storage area in the cell where food, water, and/or waste is
stored.
Parts of a Plant Cell
16. Cytoskeleton – Protein fibers that aid in the internal movement of cell organelles, as well as muscle fiber
contraction.
Parts of a Plant Cell
17. Centrosome – Aids in cell division.
Parts of a Plant Cell
18. Lysosomes – Small round structures that contain chemicals that aid in breaking
down large food particles into smaller particles.

13. Vaculoes – Storage area in the cell where food, water, and/or waste is
stored. Notice it is much smaller in an Animal Cell!

Parts of an Animal Cell
17. Peroxisome – Protects the cell from its own production of toxic chemicals (hydrogen peroxide)

1. Nucleoid – This is not membrane bound and is generally where the DNA
is located. Notice there is no nucleus in a bacterial cell.

5. Pilus – These are hair-like structures made of protein that allow bacteria to
attach to other cells.

6. Capsule – This layer protects the bacterial cell.

7. Flagella – Flagella are made of protein, and they help the bacteria cell
move.
