Grow and Develop – making new cells, repair of cells
Respond to Environment – adapts, reacts to stimuli
Reproduction – producing offspring
Uses/needs energy – photosynthesis & cellular respiration

34. Review
The two main processes for creating energy in a cell are Photosynthesis & Cellular Respiration but there are many more processes that ensure cell function & survival!

35. (Metabolic) Cellular Processes: The processes we will discuss…STERNGRR
Synthesis (photosynthesis would fit here)
Transport
Excretion
Regulation
Nutrition
Growth
Respiration (cellular respiration would fit here)
Reproduction

36. Synthesis How organisms build necessary materials Examples:
Protein Synthesis: making proteins
Photosynthesis: plants make food using energy from sunlight

37. Synthesis
Which organelles would mainly be involved in these processes?

38. Transport
How organisms get what they need to cells (moving materials within the organism)
Examples:
Active Transport vs. Passive Transport

39. Transport
Which organelles would mainly be involved in these processes?

40. Excretion
How organisms get rid/break down their waste and balance their fluids
Examples:
Removing anything unnecessary from the cell

41. Excretion

Examples:
Important to homeostasis - to maintain balance within the body and adapt to changes
Sweating – reduces body temperature

43. Sweating – reduces body temperature
Regulation
Which organelles would mainly be involved in these processes?
Sweating – reduces body temperature

44. Nutrition How organisms get or obtain food Examples:
Fungi decompose dead remains (decomposer)
Plants make their own food (autotroph)
Animals consume other organisms and absorb food (heterotroph)

45. Nutrition
Which organelles would mainly be involved in these processes?

46. Growth
How organisms make new cells and develop and repair necessary body parts
Example: Cell division (Mitosis)
Develop – to change due to hormonal or mental cues
Grow – to get larger in size; body size

52. 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.

53. Part 1: Create a Hypothesis…
If I leave my gummy bear baby in water until Friday, then…..because…..

54. Relationship Sets – “Self Vocab Quiz”
You will create 10 “relationship sets” or sentences to show that you understand the relationship between the vocabulary words from the last 3 lessons.
Minimum of 2 words per sentence, but no maximum.
You may repeat words, but be careful not to write the same concept over and over.

55. Relationship Sets – “Self Vocab Quiz”
Bueno (Good): Cellular respiration is the process through which animal cells create energy, and the main organelle involved in this process is the mitochondria.
No Bueno (No Good): Organisms can be both biotic or abiotic because they are made of cells.

56. Warm-Up: Write your homework – get it stamped!
Put your Cell Analogies in the basket!
If you did not turn your relationship sets in last class, please turn those in as well!

Cellular Processes – In Depth 7

57. Cellular Processes Cellular processes are things needed to keep the cell alive.
1. Photosynthesis
2. Cellular Respiration
3. Transport
Active
Passive
Diffusion
Osmosis
4. Mitosis

58. 1. Photosynthesis
Plant cells use energy from the sun, carbon dioxide and water to make food.
Reactants
Process
Products
Carbon Dioxide
Water
Energy (sunlight)
The chloroplasts take the sunlight, carbon dioxide and water to make food
Sugars (glucose)
Oxygen

59. Chemical Formula for Photosynthesis
6CO2 + 6H2O + Energy from Sunlight ---> 6O2 + C6H12O6
STOP & THINK:
Is this endothermic or exothermic?

60. 2. Cellular Respiration
Animal Cells then use the oxygen and sugars to “breathe” and make energy (ATP)
Reactants
Process
Products
Sugars (glucose)
Oxygen
The mitochondria takes the sugar and the oxygen and makes energy
Carbon Dioxide
Water
Energy (ATP)

61. Chemical Formula for Cellular Respiration
C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy
STOP & THINK:
Is this endothermic or exothermic?

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

63. 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!

64. 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?

65. Materials are moved in and out of cell using the cell’s energy
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?

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

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

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

69. Turn & Talk: Diffusion Questions
What happens when you add Kool-Aid to water?
What happens when you keep adding water?

70. 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.

71. Diffusion Demo

72. 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?

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

74. 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!

75. A Gummy Situation Part 2

76. 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

77. 4. Mitosis
The steps a cell goes through to reproduce and make more cells so an organism can grow and repair itself
New cell is an exact copy of original cell

78. Mitosis Mitosis is a process broken down into 4 parts:
Part 1: Prophase
Part 2: Metaphase
Part 3: Anaphase
Part 4: Telophase

79. Mitosis
Use your book to fill out the graphic organizer for Mitosis…Pages E82-E83
Prophase
Nuclear membrane disappears
DNA condenses into chromosomes

80. Mitosis Metaphase Chromosomes line up in the middle of the cell
Chromosomes split into two identical separate sets
The 2 sets of chromosomes pull to the opposite ends of the cell
Anaphase

81. Mitosis Telophase 2 new nuclear membranes form
The cell pinches and divides into 2 new cells!!
cytoplasm is divided which is called cytokinesis

82. Mitosis & Binary Fission
Why do you think it is important for the DNA/chromosomes to be copied before the cell divides?
What is binary fission? How is it similar and different to mitosis?

83. Cells Alive Animation Phases of Mitosis

84. Tie it all Together…
For the cells to carry out all of these processes, what do they need?
How do we get that energy?
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?

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