CELL WALL PLANT

• A thick, rigid membrane that surrounds a plant
  cell
• Gives the cell most of its support and structure
• Bonds with other cell walls to form the structure
  of the plant

3
CELL MEMBRANE

• Thin layer of protein and fat that surrounds the
  cell
• Semi permeable, allowing some substances to pass
  into the cell and blocking others.
•

5
Chloroplast

• An elongated or disc-shaped organelle containing
  chlorophyll
• Photosynthesis (in which energy from sunlight is
  converted into chemical energy - food) takes
  place in the chloroplasts

6
Cytoplasm

• The jellylike material outside the cell nucleus
  in which the organelles are located.

7
Endoplasmic Reticulum

• Folded membrane that moves materials around in
  the cell.
• Extends from the nucleus to the cell membrane and
  takes up quite a bit of space.
• Similar to a system of conveyor belts in a
  business.
• Act as tunnels in which materials move from one
  place to another within the cell.

8
SMOOTH /ROUGH ENDOPLASMIC RETICULUM

• Smooth ER transports materials through the cell
• Rough ER is covered with ribosome's that give it
  a rough appearance

9
Golgi Bodies

• Are stacks of membrane-covered sacs that package
  and move proteins to the outside of the cell.
• Golgi bodies are the packaging and secreting
  organelles of the cell.

10
Lysosome

• Also called cell vesicles
• Spherical organelles surrounded by a membrane
• They contain digestive enzymes
• Where the digestion of cell nutrients takes place

11
Mitochondria

• Where energy is released.
• Spherical to rod-shaped organelles with a double
  membrane
• Membrane is infolded many times, forming a series
  of projections (called cristae)
• Converts the energy stored in glucose into ATP
  (adenosine triphosphate) for the cell.
•  

12
NucleusThe Manager

• Spherical body containing many organelles,
  including the nucleolus
• Controls many of the functions of the cell
• Contains DNA (in chromosomes)
• Surrounded by the nuclear membrane

13
Nucleolus

• An organelle within the nucleus
• Where ribosomal RNA is produced
• Some cells have more than one nucleolus

14
Nuclear membrane

• The membrane that surrounds the nucleus.

15
Ribosome's

• Small structures in the cytoplasm that create
  proteins.
• Ribosome's are either free floating in the
  cytoplasm of a cell or attached to endoplasmic
  reticulum in a cell.

16
Vacuole

• Fluid-filled, membrane-surrounded cavities inside
  a cell
• Fills with food being digested and waste material
  that is on its way out of the cell
• Like your suitcase, a vacuole is a temporary
  storage space for the cell.
