1. Aim: What are the organelles of a cell and their functions?
Do Now: List some organelles that you already know. Can you name their functions too?
Have out HW page 197 questions 1-5, 9, 10, 12,13,14
Tuesday 10/21 background information for Science Project due
Wednesday 10/22; Read pages answer questions 189 #’s 1-5
Thursday 10/23 Exam
Project #1 due on 11/12. Any Questions?

2. Can you find these organelles?
In groups use page 174 of your text to label the animal and plant worksheets
What two structures do plant cells have that animal cells do not have?

5. Charting Cell Organelle Functions
Handout: Complete the chart in groups using textbook
Structure
Function

6. Contains the DNA (blueprints) to make proteins Chromatin
Structure
Function
Nucleus
Contains the DNA (blueprints) to make proteins
Chromatin
DNA bound to protein found inside nucleus of cell; turns into chromosomes when cell gets ready to divide
Nucleolus
Assembles the Ribosomes
Ribosomes
Actually makes the proteins by chaining amino acids
Rough Endoplasmic Reticulum
Ribosomes attached; newly made proteins enter and are chemically altered
Smooth Endoplasmic Reticulum
Without Ribosomes; contains enzymes that aid in certain chemical reactions
Mitochondria
Powerhouse of the cell. Fuels the cell with energy
Golgi Apparatus
Packages proteins and aids in transporting them out of the cell
Cell Membrane
Protects the cell from surrounding environment; selectively permeable
Lysosomes
Filled with enzymes to help breakdown carbs, lipids, and proteins for use by the cell
Vacuole
Storage unit
Chloroplasts
Found only in plant cells; aids in photosynthesis
Cell Wall
Found only in plant cells; gives cell its structure
Cytoplasm
Jellylike substance that fills cell; organelles live within it
Cytoskeleton
Proteins that help maintain cell shape and aid in cell movement
