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.

  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.

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.

  made of protein that allow bacteria to
            attach to other cells.
