Lab #10 – The Celery Experiment

Lab #10 – The Celery Experiment

Problem

How does a plant get water from its roots to its leaves?

Hypothesis 




Materials
Celery
Celery seeds
Food coloring
Water
Plastic cup
Scissors
Ruler
Hand lens
  
Procedure
 1.          Make observations of your celery seeds in the Results.
2.          Make observations of your celery stalk in the Results.
3.          Cut about 2.5 cm off the bottom of the celery stalk and make observations on the celery stalk’s cross section.
4.          Fill up a plastic cup with 250 ml of water and add two drops of food coloring.  Put your celery stalk, cross section down and leaves up, into the cup of colored water. 
5.          Make observations on your celery stalk experiment.  Make sure to include color and other details such as height, number of leaves, width of cross section, etc.

Analysis
1) What happened to your celery stalk overnight?
2) How do you know that the water reached the top of the plant (celery stalk)?
3) Look for small circles at the bottom of the stalk that are the color of the food coloring you used. (These circles are xylem, the tubes that carry water up the plant.) Draw pictures and make observations about the xylem in your celery.

Lab #9 – The Cell and its Organelles

Problem

How are plant cells and animal cells both similar and different?

Hypothesis




 Materials
I will supply: 2 zip-loc bags: inner bag = cell membrane
1 loose plastic bag: outer bag = cell wall
     Oil (cytoplasm)
     red beans, red and black beads (organelles)
     green beads (chloroplasts)
     clay or balloon (nucleus)
     water (vacuole)
Please bring: uncooked pasta, candy, uncooked rice, get creative! 

Procedure 
Step 1
Pour vegetable oil into one of your Ziploc bags until it’s about half full. The vegetable oil represents the cell’s cytoplasm.





Robinson Cartagena Lopez - RoCarLo/Demand Media
Step 2
Add a piece of cauliflower to the bag. This will be your nucleus.





Robinson Cartagena Lopez - RoCarLo/Demand Media
Step 3
Place three or four mandarin oranges as mitochondria and three or four green grapes as chloroplasts in the bag.





Robinson Cartagena Lopez - RoCarLo/Demand Media
Step 4
Pour water into a balloon until it is two or three times the size of your nucleus bouncy ball. Tie the end of the balloon and place it in the Ziploc. This will serve as the vacuole, a fluid-filled space within the cell.





Robinson Cartagena Lopez - RoCarLo/Demand Media
Step 5
Add several pieces of pipe cleaner as endoplasmic reticulum.





Robinson Cartagena Lopez - RoCarLo/Demand Media
Step 6
Add a piece of ribbon candy to represent the Golgi apparatus and a small marble for the centrosome.





Robinson Cartagena Lopez - RoCarLo/Demand Media
Step 7
Sprinkle in a small handful of sesame seeds. These will represent the cell’s ribosomes.





Robinson Cartagena Lopez - RoCarLo/Demand Media
Step 8
Add more vegetable oil to the bag, if needed, until it is fairly full but still has plenty of give. Close the bag.





Robinson Cartagena Lopez - RoCarLo/Demand Media
Step 9
Maneuver the organelles so they are spread throughout the bag. Make sure your centrisome and Golgi apparatus end up near the nucleus, as this is how they’re situated in a real cell.





Robinson Cartagena Lopez - RoCarLo/Demand Media
Step 10
Place the bag inside your second Ziploc bag. If it doesn’t fit easily, pour out oil until it does.





Robinson Cartagena Lopez - RoCarLo/Demand Media
Step 11
Drizzle a little bit of oil in the space between the two bags. This represents the cell membrane, a thin, semi-permeable membrane between the cell wall and the rest of the cell. Close up the second bag.
Don’t forget to label your Ziploc bags (Cell Membrane) for BOTH plant and animal cells.

Results

Animal Cell
Plant Cell



Analysis

  1. Compare/Contrast your plant and animal cells.


  1. Predict what would happen to a plant cell if it were to lose its chloroplasts.


  1. Explain the importance of the nucleus in both cells.


4.       On your gel cells, what is representing the cell membrane?  How is the cell membrane like your skin?
_____________________________________________

5.       Create your own model of an animal and/or a plant cell.  What materials would you use?  Make a list of what is going to represent the following: cytoplasm, cell membrane, nucleus, organelles, cell wall, chloroplasts.

Organism Creation Project


You are a mad scientist that has the ability to create an organism by splicing DNA from other organisms and recombining that DNA to form a new organism. 
1)Name your organism
2)From what other organisms did you collect DNA from to create your own?  What characteristics does it still have?
3)Draw a picture of your creation
4)Write a description of your organism and link it to the traits that determine what it means to be alive: 1) Living things are organized, 2) Living things grow and develop, 3) Living things respond, 4) Living things maintain homeostasis, 5) Living things use energy, 6) Living things reproduce, 7) Living things have a life span
5)In your description, tell us about how your organism acquires its “needs” i.e. food, water, shelter


Palmizzard

The palmizzard is the organism that I’ve created.  I created it using the DNA from a lizard and a palm tree.  It has palm leaves growing from its back which allows it to produce its own energy with the help of radiation from the sun.  The palm leaves also provide shelter for the palmizzard; it lives on hot desert islands, so it needs protection from the sun which the palm leaves provide.  It has coconuts growing from its tail which it uses in times of self-defense.  It cannot run fast, so it needs camouflage that the palm leaves provide.  It is 4 feet in length as an adult.  The palm leaves help trap water so that when it rains, which is rarely on a desert island, the leaves collect the water for future use.  It eats insects and fruit that has fallen to the ground.  It mates twice a year and gives birth to live offspring.  If attacked, it will use its tail in self-defense and, if necessary, it will drop its coconuts to keep the animal attacking it busy as it flees.  The palmizzard excretes its waste 3-4 times a day. Its cells are a combination of plant and animal cells.

Chapter 8 - The Study of Living Things and their Interactions in the Environment


Chapter 8 - The Study of Living Things and their Interactions in the Environment

Living things, or organisms, have an incredible amount of diversity.  Unicellular bacteria live in our intestines whereas multicellular blue whales swim in the oceans.  No matter the differences that separate the vast array of organisms, we share some common traits.

1) Living things are organized; the smallest unit of an organism that carries on the functions of life is a cell.

The single celled yeast, Saccharomyces cerevisiae, is used in baking bread.


Here is a picture of nearly a dozen Saccharomyces cerevisiae clumping together.  Each one of these is an organism.

The largest living reptile today is the saltwater crocodile.  An adult male can grow to the length of 9.0–5.5 m (13–18 ft) long. 




Crocodylus porosus

The saltwater crocodile is a multicellular organism made up of trillions of cells.


In this image, pig cells connect with each other to form tissue in the pig's nose.


Billions of cells working together are the basic unit of organization that gives form to the multicellular pig.


2) Living things grow and develop
Salmon eggs


Full grown adult salmon with eggs


3) Living things respond to a stimulus


4) Living things maintain homeostasis


5) Living things use energy

6) Living things reproduce




All living things need food, water and shelter

1) Living things need food

2) Living things need water

3) Living things need shelter
