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