12/12 1st and 9th 12/12 ATB What is the function of the nucleus?
(look in your notes!!!)
Today:Page 9 GradedGo over page 9Start completing page 10
Cytoplasm – Portion of cell outside the nucleusIncludes the fluid, the cytoskeleton and all
organelles except nucleus
Organelle –“little organs”Specialized structures with specific function
Cytosol – the cytoplasm that includes the ribosome's but
not the membrane bound organelles – 20% protein
Nucleus – Control center of cell - Contains most of cell DNA - instructions to make proteins– controlled by the code
in your DNA
Nuclear Membrane / Envelope – double membrane that surrounds the nucleus
Nuclear Pore – protein lined holes in the nuclear membrane that
allow RNA to enter / leave nucleus
Nucleolus – Dense region of DNA that assembles / create
ribosome’s
11/19 11/19 ATB What three structures did you
see yesterday in the cheek cell?
Today:Review the cell organelles
Finish the lab / print out your documentsLab due Wednesday
Chromosome – DNA coils to form chromatin – chromatin coils
to form chromosomesChromatin is how the cell’s DNA is stored when
not replicatingChromatin coils to form chromosomes when
replication is occurring
Organelles that Store, Clean Up and Support
Vacuole – Large membrane-enclosed saclike
structureStores materials like water, salts,
proteins, carbs, etc.Larger in plant cells than animal cells
Vesicle – Membrane-enclosed structureUsed to carry contents around, into / out
of cellSpherically shaped
Are materials moving into or out of the cell in the diagram below?INTO
Central vacuole – large organelle that stores water,
enzymes, wastes, in a plantTake up a large amount of the plant cellIf filled with water, how will plant stand?
Upright – if they are lacking water, plant will droop
Lysosome – Small organelles filled with enzymes (vesicle that contains digestive enzymes
produced by Golgi)
Digest organic materials, bacteria, etcBreak down lipids, carbohydrates and proteins so
they can be used by the cell
Cytolysis or autolysis – lysosomes release enzymes to destroy the cell (old or malfunctioning cells)

Organelles That Build Proteins
Ribosome – proteins that direct protein synthesisConsist of two subunits
Endoplasmic reticulum (ER) – An internal membrane systemFunction – packages proteins / other
substances made on it’s surface into vesicles
Sends protein vesicles to golgi apparatus
Rough ER – contains ribosome'sCalled “rough” b/c it has ribosomes on
it’s surfaceProduces vesicles with proteins in them
Smooth ER –Lacks ribosomesProduce lipids (phospholipid) and
hormones in sex cells (like estrogen & testosterone)
ER
Golgi Apparatus -Flattened stack of membranesFUNCTION - Receive vesicles from ER and modify
them as they move through the Golgi (get “address labels”)
Vesicles then are sent to various locations (around / out of cell)
“Finishing touches”Create lysosomes
ER

Organelles that Capture and Release Energy
Chloroplast – What can they be compared to?
Solar panelsMembrane bound organelleFunction:Use light energy to make chemical energy
(carbohydrates) through photosynthesis
Chlorophyll –green pigment that absorbs light energy in plants
Plastid –
plant organelles that have their own DNA and perform specific functions (Example: Chloroplasts)Thylakoids – flat membranous sacs that contain chlorophyll
(where photosynthesis takes place)
Mitochondria – Can be compared to a power plant (“Power
house” of the cell)Membrane bound organelle Function:Takes organic molecules (ex: carbohydrates) and
makes energy ( ATP - adenosine triphosphate)Inner membrane has many folds for reactions to
occur (called cristae)Which cells would you think have the most
mitochondria? Muscle cells
Cell Boundaries
Cell wall – Rigid layer found outside plasma
membraneFunction:Supports / gives shape / protect the
plant cellContain celluloseGives plants their structure
Is the cell wall porous?Yes, it must allow certain needed
substances to pass through (water, oxygen, CO2, others)
Plasma / Cell membrane Made of two layers of phospholipids (a bilayer) Functions:
Regulates what enters / leaves the cellHelps protect cell from bacteria and keep cell shapeChemical communication with other cells
Review: Hydrophobic =Hydrophilic =
Phospholipid – contains hydrophobic tails and hydrophilic head
Plasma Membrane
Selective PermeabilitySelective Permeability -
Membranes only allow certain materials to pass through them.
Important to allow certain substances in, and keep others out
Fluid Mosaic Model(put this under Selectively Permeable in your notes)
Fluid Mosaic Model - Idea that the components of the plasma membranes
(phospholipids, proteins, etc) are constantly flowing / moving
Fluid Mosaic Model

Membrane Proteins:
Integral proteins – Proteins in the plasma
membrane that are embedded or pass all the way through the membrane
Have carbohydrate attached to act as marker or label
Function:CommunicationTransporting materials into cell
Peripheral proteins –
proteins found only on one side of the membrane
Membrane contain lipids called sterols (cholesterol) help make membrane more firm
and prevent freezing at lower temperatures
Plant Cell
Group Test Directions:You will discuss the questions with your group,
then answer them.
You will have ½ the period to do this.
You will then exchange your test with another group and they will grade it.
You will get a % of the points you earnFor example, if you get 25 points, I’ll add a 5th of
those points on your test grade, or 5 points
Pg 761. Skin: shape: like plates function:
protective layer for the body
2. Surface area to volume ratio limits cell size.
3. 3 things all cells have: plasma membrane (protective layer), cytoplasm (mush & organelles), nucleus (control center)
4. diff. bet. Prok. & euk.: Prokaryotic cells lack membrane bound organelles and nucleus. Eukaryotic cells HAVE a nucleus and membrane bound organelles
Pg 761. Nerve cell: Shape long thin extension of cell
Function sends / receives nerve impulses
2. Cell size is limited by the cell outer surface area to it’s volume
3. Basic cell parts: plasma membrane (outer layer), cytoplasm (jelly like inside), nucleus (control center)
4. diff. bet. Prok. & euk. Cells: eukaryotic have nucleus, membrane bound organelles
Prokaryotic no nucleus, no memb. Bound organelles
Teach an organelle:
Groups of two w/ one laptop
Time to prepare = 10-15 minutes
Task: Prepare one ppt slide including a student friendly def. + at least 1 picture.
1 student will present def to class + the other will explain the picture's) (I will decide who does what so both of you should be ready to do either!).
Presenting time = 45 seconds – 1 minute …PRACTICE
Cell Organelle PowerPoint – Directions – 35 points
You are going to create a PowerPoint that illustrates information about each cellular organelle.
Each organelle must be identified with an image and you must explain it’s function.
You must also identify plant organelles and compare / contrast the differences they have from animal cells.
Your PowerPoint will be graded for the detail of it’s information and pertinence of it’s images
You will submit your presentation to me (using a flash drive) or you can post it to the wikispace.
