Photosynthesis

• Lets write the chemical equation on the board!!
• What are the reactants, What are the products?
• What type of energy transformations are going on?

12
Based on the graph below, what color is this
object

• Red
• Orange
• Yellow
• Blue
• Violet

13
First why do leaves change colors??
14
Below is the absorption spectrum for the spinach.
Discuss with your partner the most
useful/absorbed part of the visible light
spectrum and the least useful/absorbed part of
the spectrum.
15
Based on the graph, what color is this plant

• Green
• Red
• Violet

16
Based on the graph, what colors are best absorbed
by this plant

• Green and orange
• Red and violets
• Violet and green
• 4. Green and reds

17
Energy

• Combustion

Cell Respiration

• Lets draw the chemical formula on the board!!
• What are the reactants, What are the products?
• What type of energy transformations are going on?

22
Are your cells respirating right now???
23
So how do you get glucose in your body?

• And what is it exactly??

24
Its a cycle in plant cells, Jennnnay
25
The process of cellular respiration is taking
place in your cells right now!!

• You are currently taking in oxygen and burning
  sugars within the mitochondria to release
  chemical energy.
• This process is also known as Aerobic
  Respiration. Why?
• Because Oxygen is present which allows your cells
  to burn glucose into energy much more
  efficiently.
• I am sure you have heard of Aerobics.

26
What would happen if your cells were deprived of
oxygen?? Would they still be able to burn glucose
to make energy??

• YES!!
• Fermentation
• When might this occur?
• Long distance runners often create an anaerobic
  environment for their cells
• What does anaerobic mean??
• No Oxygen present
• Not a very energy efficient process and a bad
  side effect is produced
• Lactic Acid

27
A different example of fermentation

• Breweries rely on this process
• Yeast cells need energy to survive, so they will
  breakdown sugars in anaerobic conditions and a
  byproduct is alcohol.
• How do you know CO2 is produced?

28
Based on the graph, what color is this plant

• Green
• Red
• Violet

29
Based on the graph, what colors are best absorbed
by this plant

• Green and orange
• Red and violets
• Violet and green
• 4. Green and reds

30
Based on the graph below, which color light is
least absorbed by plants for photosynthesis

• Red
• Yellow
• Green
• Orange
• Violet

31
What is this graph showing you??

32
A scientist wants to study photosynthesis in a
newly discovered species. Which of these cell
structures should the scientist study?

• Vacuoles
• Chloroplasts
• Mitochondria
• Ribosomes

33
Muscle cells require more energy than do most
other cells. Which organelles would you expect
to find in greater abundance in muscle
cells than in most other cells?

• Cilia
• Mitochondria
• Ribosomes
• Chloroplasts

34
Which of these processes results in carbon
dioxide production?

• Osmosis
• Respiration
• Evaporation
• Photosynthesis

35
Some organisms that live in the intestines of
cows do not require oxygen to survive. Which of
these best describes the process by which
these organisms obtain energy?

• Osmosis
• Mitosis
• Cellular respiration
• Fermentation

36
Lets fill in this chart with the molecules and
then the energy transformations
