Final Exam Review

The Sequel


Chapter 10 lesson 1

Chapter 10 Lesson 1

Energy Processing in Plants


How do materials move through plants
How do materials move through plants?

  • Vascular tissue

    • Xylem – water enters through roots, water and nutrients carried to all parts

    • Phloem – carries liquid sugar from photosynthesis

    • Stomata - Carbon dioxide, water vapor, oxygen


How do plants perform photosynthesis
How do plants perform photosynthesis?

  • Capture energy in light

    • Occurs in chloroplasts

    • Chlorophyll reflects green light and makes plants appear green, absorbs other light

  • Water molecules split apart

    • Releases oxygen

      Carbon dioxide + hydrogen (from water) + light = sugar + oxygen


Photosynthesis
Photosynthesis

carbon dioxide + water  sugar + oxygen

light energy

6CO2 + 6H2O  C6H12O6 + 6O2

chlorophyll


What is cellular respiration
What is cellular respiration?

  • Releases energy stored in the chemical bonds in food

  • Used to make ATP, useable form of energy

  • Occurs in the cytoplasm and mitochondria

  • Most organisms (plants and animals)

    Glucose + oxygen  carbon dioxide + water + ATP (energy)

    C6H12O6 + 6O2  6CO2 + 6H2O + ATP


What is the relationship between photosynthesis and cellular respiration
What is the relationship between photosynthesis and cellular respiration?

  • Photosynthesis requires light, carbon dioxide, and water and results in sugar/glucose and oxygen

  • Cellular respiration uses the products of photosynthesis (sugar/glucose and oxygen) and results in carbon dioxide, water, and ATP

  • Plants, some protists, some bacteria do photosynthesis

  • Almost all plants and animals do cellular respiration

Chapter 20 Lesson 1 respiration?

Abiotic Factors


What are the nonliving parts of an environment
What are the nonliving parts of an environment? respiration?

  • Necessary for a well-functioning ecosystem

  • The Sun

    • Source of almost all energy

    • Warmth and light

    • Affects climate and temperature

  • Climate

    • Average weather conditions

    • Includes temperature, moisture, wind

    • Influences where an organism can live


Abiotic factors continued
Abiotic respiration? Factors continued

  • Temperature

    • Influences where an organism can survive

  • Water

    • Required for all life

    • Most organisms are made mostly of water

    • Every ecosystem must contain some water to support life

  • Atmosphere

    • Mostly nitrogen and oxygen

    • Protection from the harmful rays of the Sun


Abiotic factors continued1
Abiotic respiration? Factors continued

  • Soil

    • Rocks, water, air, minerals, remains of organisms

    • Ecosystem

    • Water, soil texture, and nutrients affect what organisms can live in soil


Chapter 20 lesson 2

Chapter 20 Lesson 2 respiration?

Cycles of Matter


How does matter move in ecosystems
How does matter move in ecosystems? respiration?

  • Water Cycle

    • 70% of Earth

    • 97% of water is in oceans

    • Evaporation, transpiration, exhalation, cellular respiration put water vapor into air

    • Condensation – clouds

    • Precipitation


  • The Nitrogen Cycle respiration?

    • Part of proteins, DNA

    • Nitrogen has to be “fixed”

      • Lightning

      • Bacteria – soil and atmosphere

    • decaying matter

    • Waste

    • Plants take in nitrogen


  • The Oxygen Cycle respiration?

    • respiration and photosynthesis

    • Oxygen and carbon dioxide

  • The Carbon Cycle

    • Atmosphere: combustion, cellular respiration

    • Water: photosynthesis

    • Soil: plants, protists, bacteria, decomposition
