5 Characteristics of a Living Thing - Expanded Details  Organized Structure - cells & their organelles - DNA/genetic codes  Grow and Develop – making new cells, repair of cells  Respond to Environment – adapts, reacts to stimuli  Reproduction – cells duplicating; producing offspring  Uses/needs energy – photosynthesis & cellular respiration

Cellular Processes: The processes we will discuss…STERNGRR! 1. Synthesis (photosynthesis would fit here) 2. Transport 3. Excretion 4. Regulation 5. Nutrition 6. Growth 7.

R eproduction  Which organelles would mainly be involved in these processes?

A Gummy Situation  We are going to use your gummy bear to demonstrate some of the cellular processes and vocabulary next class.  Name your gummy bear, and write the name on the masking tape.  Fill your container with water – enough to cover a gummy bear, but not so much that it will spill out when you place the bear in!  Put your bear in the water filled container, put the lid on, and put the masking tape label over the lid.

A Gummy Situation Part 1: Create a Hypothesis…  If I leave my gummy bear baby in water until next class, then…..because…..

Classwork/Homework: Work on your own illustrated set of analogies for the organelles inside an animal cell, and you must include: Name & function of each organelle! Illustration for each organelle we covered in class! Explanation of the analogy!  Example: If your theme was school: The principal would be the nucleus because they control the school and make decisions like the nucleus does in the cell.

Cellular Processes Cellular processes are things needed to keep the cell alive! 1. Synthesis – as in photosynthesis 2. Respiration – as in Cellular Respiration 3. Transport Active Passive  Diffusion  Osmosis 4. Reproduction – as in mitosis, meiosis & binary fission

1. Photosynthesis  Process that plant cells use to make energy! ReactantsProcessProducts  Carbon Dioxide  Water  Energy (sunlight) The chloroplasts take the sunlight, carbon dioxide and water to make food  Sugars (glucose)  Oxygen

Chemical Formula for Photosynthesis  6CO 2 + 6H 2 O + Energy from Sunlight ---> 6O 2 + C 6 H 12 O 6 STOP & THINK:  Is this endothermic or exothermic?

2. Cellular Respiration  Process animal cells use to make energy! ReactantsProcessProducts  Sugars (glucose)  Oxygen The mitochondria takes the sugar and the oxygen and makes energy  Carbon Dioxide  Water  Energy (ATP)

Chemical Formula for Cellular Respiration  C 6 H 12 O 6 + 6O 2 → 6CO 2 + 6H 2 O + Energy STOP & THINK:  Is this endothermic or exothermic?

Turn & Talk: Cellular Respiration Question  Why do you breathe more when you’re running around than when you’re sitting watching television?

Cellular Respiration Answer Because you’re requiring more energy when you run than when you’re just sitting watching TV right? So if you need more energy, then you need more oxygen to give you that energy so your cells undergo respiration!

3. TRANSPORT  Things have to move in and out of the cell  There are 2 types of transport Active Transport Passive Transport Remember: Which organelle allows things to enter or leave the cell?

Active VS. Passive  Materials are moved in and out of cell using the cell’s energy  Materials are moved in and out of cell WITHOUT using the cell’s energy Remember: Which organelle makes the energy for the cell again? What is that process called when the cell makes energy?

Passive Transport  The cell uses 2 main processes to passively move materials in and out of the cell. Diffusion Osmosis

Diffusion  Process by which molecules spread out Move from areas of HIGH concentration to LOW concentration BUT WHY??

Equilibrium  Molecules don’t like to be crowded, so they spread out, or diffuse, until their concentration is equal everywhere, which is called equilibrium.

Diffusion Demo

Turn & Talk: Diffusion Questions  What happens when you add Kool-Aid powder to water?  What happens when you keep adding water or when you keep adding Kool-Aid?

Diffusion Review Answer  The Kool-Aid begins to diffuse throughout the water until the Kool-Aid reaches equilibrium.  The Kool-Aid becomes less concentrated (both the color and the flavor) as you add more water, or more concentrated as you add more Kool-Aid.

Osmosis  The diffusion of water through a membrane Remember: Which organelle would store water in the cell?? Which organelle would the water have to pass through to enter the cell again?

Turn & Talk: Osmosis Question  Why do your hands get wrinkly when you’re in the water for a long time?

Osmosis Review Answer  When your hands are in water for a long period time you wash off the oily substance that keeps water from entering your skin. So once that oily layer is washed away your skin becomes semi-permeable and water passes through the membrane, which is osmosis. Your hands become wrinkly because they are trying to reach equilibrium with the water, but only some of your skin is actually attached to the tissue underneath!!  BONUS – it is an evolutionary adaptation that helps us grip wet objects!

A Gummy Situation Part 2

Let’s take a break and check on our Gummy Bear Babies…  Using the following vocabulary words, explain what happened to your baby: Transport (distinguish whether it is active or passive) Osmosis Diffusion/Diffuse Concentration Equilibrium

4. Reproduction  What is the difference between… Mitosis Meiosis Binary Fission

4. Mitosis - Asexual  The reproductive process to ensure an organism can grow and repair itself  New cell is an exact copy of original cell  Creates every type of cells OTHER than sex cells!

4. Meiosis - Sexual  The reproductive process to ensure offspring are created  The combination of genetic material from 2 different cells  Creates sex cells ONLY!

4. Binary Fission - Asexual  Most common form of reproduction in prokaryotic cells and some single- celled eukaryotic organisms  This is how bacteria replicate so quickly!

Turn & Talk: Mitosis & Binary Fission  Why do you think it is important for the DNA/chromosomes to be copied before the cell divides?  How binary fission similar to mitosis?

Tie it all Together…  For the cells to carry out all of these STERNGRR processes, what do they need?  How do we get that energy for them to use?  Do all foods give us the same nutrients and therefore amount of energy?  So, how do we ensure that our cells stay healthy and are able to function?

HOMEWORK  Bring in a nutrition label from any food next class…feel free to bring extras for those who “forget!”
