Cell organelle presentation Cell organelle presentation Presentation Transcript

  • Prokaryotic structures, Eukaryotic Organelles.
  •  Be able to identify cell structures and organelles on a diagram. Be able to state the function of cell structures and organelles. Know which organelles and structures are specific to prokaryotes, animal and plant cells.
  •  Outer layer which helps a cell adhere to surfaces, or be slippery to avoid antibodies. Found in prokaryotes. Review: What is an example of a prokaryote?
  •  Is a rigid layer surrounding plant, fungi and prokaryotes. It protects cell contents, and imparts rigidity to the plant, fungi, etc.Are plants prokaryotic, or eukaryotic?
  •  Separates the interior of all cells from the outside environment. It is the gate keeper, it controls what comes into and goes out of a cell. Also referred to as a phospholipid bilayer, or the fluid mosaic model. Found in prokaryotes, plants, and animals.Are lipids hydrophobic, or hydrophilic? What does this mean?
  •  Gel-like substance residing between the cell membrane holding all the cells internal sub- structures. Found in prokaryotes, plants, and animals.
  •  Sites where cells produce proteins at the direction of DNA. Are not bound by a membrane. Are made in the nucleolus out of RNA and protein. May be free in cytoplasm, or bound to the Endoplasmic Reticulum (plants and animals) Are found in prokaryotes, plants, and animals.
  •  The genetic material of prokaryotic organisms. Found only in prokaryotes
  •  Hair like structure used for attaching to solid surfaces, and in the transfer of DNA from one cell to another (bacteria during reproduction). Also used for cell mobility. Found in prokaryotes.
  •  Movement in external medium. ◦ Works similar to a propeller on a boat. Found in prokaryotes and animal cells.
  •  Non-membrane bound area which contains genetic material in prokaryotes. Only in prokaryotic cells.
  • Golgi Body
  •  Is a flattened stack of tubular membranes. Sorting, packaging, processing, and modification of proteins. Can be thought of as the post office of the cell. It packages proteins into sacs called vesicles, and makes sure they get to where they belong. Found in plant and animal cells.
  • Golgi Body Lysosomes
  •  Membrane bound organelles which contain digestive enzymes. The enzyme are contained to protect the rest of the cell. Breakdown of large molecules (e.g., proteins and polysaccharides). Removal worn out parts, food particles, viruses and bacteria. Found in plant and animal cells. Review: What kind of macromolecule is an enzyme?
  • Golgi Body Lysosomes Centriole
  •  Anchor for cytoskeleton. Helps in cell division by forming spindle fibers. Found in plant, and animal cells.
  • Golgi Body Lysosomes Centriole Endoplasmic Reticulum
  •  Site of cellular chemical reactions. Arranged in a series of highly folded membranes. • Folds in membranes increase surface area, which provides more room for chemical reactions to take place. Found in plant and animal cells. Smooth E.R.  Rough E.R. ◦ No ribosomes attached ◦ Has ribosomes attached ◦ Production and storage of ◦ Creates proteins for use lipids inside the cell, and to be sent out of the cell for various jobs. Review: What are the functions of lipids? What is a protein made of?
  • Golgi Body Lysosomes Centriole Endoplasmic Reticulum Nucleolus
  •  Located within the nucleus. It is the site of ribosome production. Found in plant and animal cells.

  • Golgi Body Lysosomes Centriole Endoplasmic Reticulum Nucleolus NucleusCell Membrane Ribosomes Cytoplasm
  •  Control center of the cell. Place where DNA is stored and maintained. DNA is the directions for making proteins. Site of RNA transcription (for making proteins, and duplicating DNA) Contains the nucleolus, which is where ribosomes are made. Found in plant and animal cells.Review: What macromolecule makes up DNA?
  • Golgi Body Lysosomes Centriole Endoplasmic Reticulum Mitochondria Nucleolus NucleusCell Membrane Ribosomes Cytoplasm
  •  Is the power plant of the cell. Transforms energy from the breaking down of glucose into ATP (adenosine triphosphate) which is used for energy by other organelles. Have and outer membrane, and an inner membrane with a lot of folds called cristae. The folds increase the surface area for the storage of more energy- storing molecules. Cells which require more energy have more mitochondria in them. ◦ For example: Muscle cells have more mitochondria than skin cells because they require more energy. Found in plant and animal cells. Review: What type of macromolecule is glucose?
  • Golgi Body Lysosomes CentrioleNuclear Pore Endoplasmic Reticulum Mitochondria Nucleolus NucleusCell Membrane Ribosomes Cytoplasm
  •  Nuclear pores allow the transport of water- soluble molecules across the nuclear envelope. RNA and ribosomes move from nucleus to the cytoplasm. Proteins (DNA), carbohydrates and lipids move into the nucleus. Found in plants and animals.
  • Golgi Body Lysosomes CentrioleNuclear Membrane Nuclear Pore Endoplasmic Reticulum Mitochondria Nucleolus Nucleus Cell Membrane Ribosomes Cytoplasm
  •  Double membrane, separating the contents of the nucleus (DNA in particular) from the cytoplasm. Found in plants and animals.
  • Golgi Body Lysosomes Centriole VesiclesNuclear Membrane Nuclear Pore Endoplasmic Reticulum Mitochondria Nucleolus Nucleus Cell Membrane Ribosomes Cytoplasm
  •  Materials packaged at the Golgi apparatus are transported in vesicles. Storage, transportation, helps maintain homeostasis by moving packaged materials to the cell surface for release out of the cell. Found in plants and animals.
  • Vacuole Golgi Body Lysosomes Centriole VesiclesNuclear Membrane Nuclear Pore Endoplasmic Reticulum Mitochondria Nucleolus Nucleus Cell Membrane Ribosomes Cytoplasm
  •  Membrane bound compartment for temporary storage – food, enzymes, waste, etc. Small in animal cells. Very large in plant cells where they store water for the plant.

  • Vesicles Lysosomes Nucleus Endoplasmic Reticulum Cytoplasm Nucleolus Golgi Body Nuclear MembraneChloroplast Ribosomes Mitochondria VacuoleCell Membrane
  •  Site of photosynthesis – using sunlight to produce energy. Contains the pigment chlorophyll, which traps light and give leaves their green color. Found mainly in plants, and some protists (mostly unicellular eukaryotes).

  •  In plants the cell wall is made up of cellulose. It helps provide structure and rigidity for the plant. It protects the cells. Found in plants and prokaryotes.
  •  Cillia: hair like structures around a cell to provide motion. In prokaryotes, plants, and animals. Cytoskeleton: interior scaffolding, plays important roles in both intracellular transport and cellular division. Found in prokaryotes, plants and animals. Thylakoid: Responsible for photosynthesis in protists, and are found inside chloroplasts. They are made of stacks of discs called grana.
  • Remember…All cells have a cell membrane.Prokaryotes have no membrane bound organelles.Prokaryote DNA is not in a nucleus, and eukaryotic DNA is.Plant cells have chloroplasts, large central vacuoles, and a cell wall; animal cells do not.
