Characteristics of all living things is that they all use…. Energy. Two ways organisms get their energy (food). Autotophic Heterotrophic. Autotroph & Heterotropoh. autos - Greek for “self” hetero – Greek for different trophos - Greek for “feed”. Photo auto trophs. Photo auto trophs.

Autotroph & Heterotropoh

autos - Greek for “self”

hetero – Greek for different

trophos - Greek for “feed”

bacteria used to be in the kingdom monera moneres means single all bacteria are single celled
BacteriaUsed to be in the Kingdom Monera. “moneres” means single. All bacteria are single celled.

Are bacterial harmful ?

Beneficial ? Both ?

bacteria domain prokarya
Bacteria – Domain Prokarya

Kingdom Eubacteria

First appeared in the

Precambrian Era

Cyanobacteria – Also

Known as “blue green

algae

how eubacteria are identified
How Eubacteria are identified
  • Gram + bacteria turn purple when stained.

Absorb a violet stain

  • Gram – bacteria appear pinkish when stained. Outer layer of carbohydrate and protein absorbs pinkcolor

Archaebacteria

Methanogens produce

methane gas

The straight poop about cow poop!
  • Methanes heat trapping power is 21 times greater than carbon dioxide.
  • 1.3 billion cows. Global pop. of cows as doubled in the last 40 years
  • Methane gas levels have doubled in atmosphere
  • Cow expels 600 liters of methane a day!
stoma means mouth
Stoma means “mouth”

What do you think

passes through

the stomata?

what is a pigment
What is a pigment
  • Pigments are chemical compounds which reflect only certain wavelengths of visible light. This makes them appear "colorful". Flowers, corals, and even animal skin contain pigments which give them their colors.
pigments absorb wavelengths of light
Pigments Absorb wavelengths of light
  • More important than their reflection of light is the ability of pigments to absorb certain wavelengths.
slide44
Why?
  • The reason why red and blue is the most important is because they are absorbed by the pigment chlorophyll and green light is reflected
slide47
With carbon dioxide

No carbon dioxide

the 5 things needed for photosynthesis are
The 5 things needed for photosynthesis are…..
  • Chloroplast - Place
  • Sunlight - Energy
  • Chlorophyll – Captures the energy !
  • Carbon Dioxide – 2 of the 3 elements needed to make glucose. C & O
  • Water – Electron and hydrogen
what is in the leaf that makes it bluish black purple like
What is in the leaf that makes it bluish-black-purple like ?
  • Starch and starch is a polysaccharide. Which means that it is made of a bunch of glucose units hooked together. Therefore glucose is produced
the goal of photosyntheis is
The goal of photosyntheis is…
  • to make glucoseC6 H12 O6 from

CO2 and H2 Oand O2 is produced as a by product

  • Therefore we must get the Hfrom H2 O to combine with CO from CO2 to make glucoseC6 H12 O6

  • Light Reactions
  • Dark Reactions

Overview of the light reactions

Do you see where you get

the oxygen that you breathe?

There are two “photosystems inside

each thylakoid membrane.

Photosystem 1 was the

first one discovered

Photosystem 1

P700

Photosystem 2

P680

High or low potential

energy?

ATP

No NADPH or

Oxygen is made

Electrons are returned to

chlorophyll so this is is

called Cylclic

summary of light reactions
Summary of Light Reactions
  • Energy from sunlight is absorbed by chlorophyll and excites electrons.
  • Electrons are passed through the ETC causing H+ ions to move inside the thylakoid.
  • Water is split and makes oxygen. Oxygen is released. Free H+ flows through by chemiosmosis and makes ATP.
  • H+ join up with NADP to make NADPH which proceeds to the stroma where dark reactions occur.
what is needed for the dark reactions
What is needed for the dark reactions?
  • Carbon Dioxide - C , O
  • NADPH - H
  • ATP

Differentiate between prokarya and eukarya

Define “auto” and “trophos” “photo” “synthesis” “chloro”

Identify the photoautroph kingdoms. Identify at least two from each kingdom

Explain why bacteria used to be in the kingdom Monera

Explain how cows are contributing to global warming

Differentiate between Gram + and Gram – bacteria

Label the cross-section of a leaf and the biological significance of xylem, phloem, mesophyll, and stomata.

Recognize the equation of photosynthesis and identify the ingredients and products

Define pigment

Explain the role of chlorophyll in photosynthesis

Identify the organelle of photosynthesis and be able to label all of its parts

Explain why chlorophyll is appears green

Identify which colors of light are the least and most important in photosynthesis

Explain the role of NADP, ATP, Carbon Dioxide in photosynthesis

Identify where in the chloroplast the light and dark reactions

Explain how chemiosmosis occurs and its importance

Explain how carbon dioxide is changed into glucose

Explain the role of water in the light reactions

Differentiate between the light and dark reactions

Identify the other name of the dark reactions

Explain why crabgrass and corn grow so well in the hottest times of the year.

Give the straight poop about cow poop.
