Tuesday, June 09, 2015 Objective: YWBAT relate the cell organelles’ functions to other situations in life. Drill: Why is water such an essential part of all living things?Homework Study Vocabulary and Notes Cell Unit Test Wednesday October 29 th

Today’s Agenda Drill Cell Organelle Review/Notes Cell Organelle Analogy Conclusion

Answer Water is essential to the health all living things...because water ensures the proper functioning of cells that make up living things.

Cell Organelles Eukaryotic Cells

Cell Parts Cells – the basic unit of life Organelles - small structures inside a cell with specific functions. Analogy – Town of Stevensville

A) Cell Membrane/Plasma Membrane Analogy – Stevensville city limits 1.Function: Regulates materials entering and exiting the cell. 2.Structure: Two layers of phospholipids, proteins Cell membrane

B) Cytoplasm 1.Function: All cell contents that lie between the cell membrane and the nucleus. (organelles + cytosol) a. Cytosol = liquid portion/non-organelles. 2.Structure: made up of fluid and organelles except for nucleus Analogy – All air, water, life that are in Stevensville, except City Hall Cytoplasm

C) Nucleus 1.Function: “Control Center.” Regulates DNA & RNA actions. 2.Structure: membrane bound, contains DNA Analogy – City Hall Nucleus

D) Nuclear Envelope Analogy – Walls & Doors of City Hall 1.Function: Regulates what enters or exits the nucleus. 2.Structure: Double Layer of Lipids Nuclear Envelope

E) Nucleolus Analogy – The Mayor 1.Function: Produces RNA, which are used to make all proteins. 2.Structure: Inside Nucleus, separate from DNA Nucleolus

F) DNA – Deoxyribonucleic acid Analogy – The Laws or City Code 1.Function: information on how to make proteins. a.Chromatin – unorganized DNA (normal state) b.Chromosomes – organized DNA (present before cell division 2.Structure: Made up of nucleotides, locked in the nucleus DNA (chromatin)

G) Endoplasmic Reticulum Analogy – Roads & Sidewalks 1.Function: Transportation route for proteins. a.Rough ER: has ribosomes b.Smooth ER: no ribosomes 2.Structure: tubes and channels Rough ER Smooth ER

H) Ribosomes Analogy – Restaurants, Factories, Builders. 1.Function: Makes proteins. 2.Structure: small circular organelles Ribosomes Free Ribosomes

I) Vacuoles & Vesicles Analogy – Grocery stores, water tanks. 1.Function: Storage for water, nutrients or waste. 2.Structure: small membrane-bound organelle. Vesicles

J) Lysosomes Analogy – Recycling center 1.Function: packets of enzymes that break down materials in a cell. 2.Structure: Small membrane-bound organelles Lysosomes

K) Mitochondria Analogy – Delmarva Power 1.Function: Produce energy for the cell – site of cellular respiration. “The Powerhouse” 2.Structure: Double membrane-bound, kidney shaped. Mitochondria

L) Golgi Apparatus Analogy – Post Office 1.Function: Packages, labels and ships proteins out of the cell. 2.Structure: Pancake-shaped layered organelle Golgi Apparatus

M) Cytoskeleton Analogy – Wood, cement, steel beams 1.Function: Provide support and structure for the cell. a. Microfilaments b. Microtubules 2.Structure: Tubules Microfilaments Microtubules

N) Centrioles (Animals Only) Analogy – KI High School vs. QA High School 1.Function: microtubules that help divide the cell during cell division. Structure: Tubules Centrioles

O) Cilia & Flagella Analogy – Cars or bicycles. 1.Function: provides movement for the cell or objects moving by the cell. 2.Structure: a. Flagella – 1 long fiber b. Cilia – many short fibers Flagella Cilia

P) Chloroplasts (Plants only) Analogy – Solar Panels 1.Function: site of photosynthesis (converting sun and CO2 into sugar). 2.Structure: Membrane bound organelles that contain chlorophyll Chloroplasts

Q) Cell Wall (Plant cells only) Analogy – ground, rock wall 1.Function: Provides support for the cell and the plant. 2.Structure: Made of cellulose Cell Wall

Cell Parts Analogy Create an analogy (besides the city analogy) for the cell and its parts Possible ideas: –Stadium –School –Country –Restaurant –House –Mall –Waterpark

Stadium Example: Cell membrane: wall of stadium, gates Cytoplasm: everything inside the stadium. Nucleus: the control room for the stadium. Etc…
