You need Sept 27 2018 Clean paper pencil

You need: Sept. 27, 2018 Clean paper / pencil HW: Intro to Microscopes (Task sheet) Cell coloring page Warm Up: What does an animal cell look like? I CAN: identify a basic animal cell and some organelles.

Housekeeping! v. Review v. Best behavior! – Cougar Mountain/subs/drills/silent lunch v. Progress reports – YESTERDAY!! v. Data sheets, etc

Today • • Review lab, timeline, microscope CELLS – animal Organelles Housekeeping

The lead up to cells… • Robert Hooke – first to say “CELLS” b/c cork looked like empty rooms. Was looking at dead wood cells. • Anton Van Leeuvenhoek – first to say “Animalcules” as he looked at MOVING stuff…seeing LIVING organisms.

The lead up to cells… • Schleiden…looked at lots of plants and could say with confidence that all plants were made of CELLS. • Schwann…looked at lots of animals and felt confident saying that all animals were made of CELLS. • Virchow – helped the other two finally agree that CELLS come from other CELLS.

The lead up to cells… Schleiden, Schwann, Virchow are credited with the Cell Theory: • All organisms are made of one or more CELLS. • CELLS are the basic unit of structure and function in all living things. • All CELLS come from pre-existing CELLS.

Compound Microscope 2. Body Tube – gives distance between eyepiece and objective. 3. Nose Piece – holds the objectives. 5. Objectives lens closest to the slide. 7. Stage clips – Holds the slide in place. 9. Diaphragm – Controls the amount of light. 11. Light – Shines light through the slide, lens, tube. 1. Eye Piece – lens closest to the eye. 4. Arm – holds the tube and lenses. 6. Stage – platform for the slides. 8. Coarse Adjustment knob – Moves stage up/down (to focus). 10. Fine Adjustment knob – Moves stage up/down slightly 12. Base – Holds up the entire microscope.

Cells!!!

On the laptop… You may use Brain. Pop to help with microscope use AND with “building” an animal cell (and learning the parts). • Brain. Pop • Username: carrington 1 • Password: cougars • Search for “Using the Microscope” – work through • Search “Build-a-cell” (for animal cells) – work through

Amoeba Sisters – intro cells https: //youtu. be/8 Ilz. Kri 08 kk Write the names of the organelles that you hear in the video.

Cells and their Organelles • Organelles are like organs…but MUCH smaller. 1. At what level of organization does life begin? 2. What surrounds all cells? 3. What is meant by semi-permeable?

Cells and their Organelles • Organelles are like organs…but MUCH smaller. 4. The cell membrane is also called the ________ membrane. 5. Centrioles are found inside what type of cell? 6. What additional layer is found around the outside of a plant cell?

Cells and their Organelles DNA = deoxyribonucleic acid 7. Where is DNA found inside the cell? 8. What cell process is controlled by the nucleus? 9. DNA coils tightly during division and assembles into visible _________.

Cells and their Organelles DNA = deoxyribonucleic acid • Where are organelles located? • Where are proteins made in the cell? • Do all cells need ribosomes? • The process of making proteins is called _________________.

Cells and their Organelles Endoplasmic reticulum • • • How does rough ER differ from smooth ER? Rough ER is connected to the ____________ and to the __________ ER. Proteins made by rough ER travel to the Golgi in

CELLS

Cell Membrane • BOTH Plant and Animal Cells • Function: controls what substances enter and exit the cell • Analogy to City: City “Gate Keeper”

Cell Wall • PLANT CELLS ONLY • Function: surrounds plants to protect and support the cell • Analogy to City: City Border

Nucleus • BOTH Plant and Animal Cells • Function: directs all the cells activities (brain of cell) • Analogy to City: City Hall

Nucleolus • BOTH Plant and Animal Cells • Function: makes ribosomes inside the nucleus • Analogy to City: Copy Machine Inside City Hall

Nuclear Membrane • BOTH Plant and Animal Cells • Function: controls what enters and leaves the nucleus, protects • Analogy to City: gate around City Hall

Chromosomes • BOTH Plant and Animal Cells • Function: contains the important blueprints of the cell or DNA • Analogy to City: City Mayor

Vacuole • BOTH Plant and Animal Cells • Function: stores food, water, waste, and other materials • Analogy to City: Warehouses, Water Towers, etc.

Chloraplast • PLANT CELLS ONLY • Function: captures energy from sunlight and produces food • Analogy to City: Solar Energy Plant

Endoplasmic Reticulum • BOTH Plant and Animal Cells • Function: built proteins and move them throughout cell or out of cell (Smooth – no ribosomes, Rough – ribosomes) • Analogy to City: City Transportation Department

Cytoplasm • BOTH Plant and Animal Cells • Function: gel-like fluid between cell membrane and nucleus, allows other organelles to float freely through cell • Analogy to City: City Yards

Ribosomes • BOTH Plant and Animal Cells • Function: produce proteins • Analogy to City: Construction Company

Lysosomes • ANIMAL CELLS ONLY • Function: contain chemicals that break down food particles and worn out cell parts • Analogy to City: Recycle or Waste Management Company

Mitochondria • BOTH Plant and Animal Cells • Function: rod-shaped organelle that produce energy (powerhouse) • Analogy to City: Energy Plant

Golgi Body • BOTH Plant and Animal Cells Post • Function: Office receives materials from the endoplasmic reticulum and sends them to other parts of the cell • Analogy to City: Post Office

The Whole City… Post Office

1. Choose the wrong statement from the following. a) Mitochondria produces most of the energy for the cell. b) Chloroplasts are “food producers. ” c) Cell wall controls the movements of materials into and out of the cell. d) Nucleus regulates and controls all cell activities, acting as the “brain” of the cell.
