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 cells
  activities.

6
Parts of a Plant Cell

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

7
Parts of a Plant Cell

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

8
Parts of a Plant Cell

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

9
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.

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

11
Parts of a Plant Cell

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

12
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.

13
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.

16
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).

17
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.

18
Parts of a Plant Cell

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

19
Parts of a Plant Cell

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

20
Parts of a Plant Cell

• 17. Centrosome Aids in cell division.

21
Parts of a Plant Cell

• 18. Lysosomes Small round structures that
  contain chemicals that aid in breaking down large
  food particles into smaller particles.

  animal cell has NO cell wall.

  food, water, and/or waste is stored. Notice it
  is much smaller in an Animal Cell!

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