Cell Song

Cells can be categorized into prokaryotic and eukaryotic cells. Cells have specific structures that each carry out specific functions inside and outside of the cell. Key Points

What are Prokaryotic Cells? cell membrane cytoplasm Plasmid Smaller and simpler. Store their DNA in a plasmid. Have cytoplasm, cell membrane and a cell wall. Prokaryotic cells do not have a nucleus or membrane bound organelles (do have ribosomes) Example: bacteria

What structures are in prokaryotic cells? Cytoplasm-the jelly-like substance that fills the cells. Cell membrane -a double layer of lipids that surrounds the cell. Plasmid- is a circular piece of DNA cell membrane cytoplasm Plasmid

What are Eukaryotic Cells? Larger and more complex Eukaryotic cells have a nucleus and membrane-bound organelles Example: Plant and animal cells. nucleus organelles cell membrane

What structures are in Eukaryotic Cells? Organelles- small “organs” within a cell that perform different functions. Nucleus (NOO-klee-uhs)-stores and protects the DNA. Nuclear Envelope- The membrane that surrounds the nucleus. Nucleolus- a small dense region of the nucleus where proteins are assembled. Chromatin- Condensed DNA

What structures are outside of cells? Pili/Cilia- Tiny hair-like structures that propel the cell. Flagella- a small tail that can move the cell. FLAGELLA Draw This! CILLIA http://www.youtube.com/watch?v=ZcvVjtBlxik&safety_mode=true&persist_safety_mode=1&safe=active

Quick Write-2 Min! What did you see in the video? How would you explain this to a friend? What does cilia and flagella allow the cells to do? http://www.youtube.com/watch?v=ZcvVjtBlxik&safety_mode=true&persist_safety_mode=1&safe=active

Draw this on page of your notebook. Prokaryotes Eukaryotes

Prokaryotes Eukaryotes Place each sentence in the correct location in your Venn diagram. Smaller and simpler Do not have membrane-bound organelles. Have cytoplasm Animal and plant cells Larger and more complex. Have a nucleus and membrane-bound organelles Do not have a nucleus. Contain genetic information. Have a cell membrane. Bacteria

Prokaryotes Eukaryotes Smaller and simpler Do not have a nucleus. Do not have membrane- bound organelles. Larger and more complex. Eukaryotic cells have a nucleus and membrane-bound organelles Contain genetic information. Have a cell membrane. Have cytoplasm

Practice # 2! Create your own prokaryotic and eukaryotic cell! Be sure to label the following structures that apply: Nucleus, nucleolus, nuclear envelope, flagella, cillia, cell membrane, cytoplasm, chromatin, plasmid,

Is it prokaryotic or eukaryotic?

Day 2

Bell ringer-complete on page The sequence of DNA below is part of a gene. How many amino acids are coded for by this segment?  5' ATCAGCGCTGGC 3' A. 4 B. 8 C. 12 D. 20 (or most missed question on quiz)

Cell Song

animal cells plant cells Types of cells bacteria cells Prokaryote - no organelles Eukaryotes - organelles animal cells plant cells

Organelles in Eukaryotes We will compare organelles in two types of eukaryotic cells – plant cells and animal cells. Organelles are found throughout both types of cells. They perform various functions within each of these cells. Notes are slides 5-18. Should spend less than 30 seconds per slide. Organelles in Eukaryotes

Cell Membrane Surrounds outside of ALL cells of cell (cytoplasm) Cell membrane Proteins Protein channel Lipid bilayer Carbohydrate chains Surrounds outside of ALL cells Composed of double layer of phospholipids and proteins Controls what enters or leaves the cell Cell Membrane

Cytoskeleton Helps cell maintain cell shape Also helps to move organelles around Cytoskeleton

Nucleus Controls the normal activities of the cell Contains the DNA Surrounded by a nuclear envelope with pores Nucleus

Can be attached to Rough ER or can be free (unattached) in the cytoplasm Ribosomes

Rough Endoplasmic Reticulum (ER) Synthesis of membrane proteins and transport vesicles Rough Endoplasmic Reticulum (ER)

Synthesis of lipids and responsible for detoxification Smooth ER

Modify, sort, & package molecules from the ER for storage or transport out of the cell Golgi Apparatus Transport vesicle

Mitochondria “Powerhouse” of the cell Generate cellular energy (ATP) through Cell Respiration Mitochondria

Lysosome Contain digestive enzymes Break down food, bacteria, and worn out cell parts for cells Lysosome

Differences between plant and animal cells Plants have the same organelles as animals plus the three “C’s” Cell Wall Chloroplast Central Vacuole (large) Specific notes that differentiate plant and animal cells are slides 15-18. Differences between plant and animal cells

Vacuole Fluid filled sacks for storage Small or absent in animal cells Plant cells have a large Central Vacuole Vacuole

Supports and protects the cell Cell Wall

Chloroplast Found only in producers Filled with chlorophyll Use energy from sunlight to make own food (glucose) Chloroplast
