Two ways organisms get their energy (food) • Autotophic • Heterotrophic
Autotroph & Heterotropoh autos - Greek for “self” hetero – Greek for different trophos - Greek for “feed”
BacteriaUsed to be in the Kingdom Monera. “moneres” means single. All bacteria are single celled.
Are bacterial harmful ? Beneficial ? Both ?
Bacteria – Domain Prokarya Kingdom Eubacteria First appeared in the Precambrian Era Cyanobacteria – Also Known as “blue green algae
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
Bacteria – Domain Prokarya 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!
What are the two most important products of photosynthesis? Glucose and Oxygen
Stoma means “mouth” What do you think passes through the stomata?
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 • More important than their reflection of light is the ability of pigments to absorb certain wavelengths.
Which colors are the most and least important in photosynthesis ?
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
With carbon dioxide No carbon dioxide
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
