  • What are the first four uses of glucose in plants?
    Respiration, sucrose transport, starch storage, amino acids
  • What are the last three uses of glucose in plants?
    Cellulose, chlorophyll, fats for storage
  • What factors affect the rate of photosynthesis?
    Light intensity, chlorophyll concentration, CO2 levels, temperature
  • What does photosynthesis convert?
    Light energy to chemical energy
  • What is the word equation for photosynthesis?
    Carbon dioxide + water --> glucose and oxygen
  • What is the chemical equation for photosynthesis?
    6CO2 + 6H2O --> C6H12O6 + 6O2
  • What is the function of the waxy cuticle in plants?
    Impermeable to water, minimizes water loss
  • What is the function of the upper and lower epidermis in leaves?
    Protection from pathogens
  • What is the function of the palisade mesophyll?
    Contains many chloroplasts for photosynthesis
  • What is the function of the spongy mesophyll?
    Has air spaces for gas exchange
  • What is the function of stomata in leaves?
    Allow CO2 into the leaf
  • What is the function of guard cells?
    Open and close stomata
  • What do plants need for growth?
    Mineral ions
  • What do plants need to produce chlorophyll?
    Magnesium ions
  • What do plants need to produce amino acids?
    Nitrates
  • How does the rate of photosynthesis change throughout the day?
    No photosynthesis at night; stomata close
  • What color does hydrogen carbonate indicator turn at high CO2 concentration?
    Yellow
  • What color does hydrogen carbonate indicator turn at normal CO2 concentration?
    Red
  • What color does hydrogen carbonate indicator turn at low CO2 concentration?
    Purple
  • What color does hydrogen carbonate indicator turn for a plant in the dark?
    Yellow
  • What color does hydrogen carbonate indicator turn for a plant in bright light?
    Purple
  • What color does hydrogen carbonate indicator turn for a plant and animal together?
    Red
  • What color does hydrogen carbonate indicator turn for a boiled plant?
    Red
  • What are the waste products of metabolism in plants?
    CO2 and O2
  • How does temperature change in a plant respiration practical?
    Germinating beans increase temperature
  • What is the word equation for aerobic respiration?
    Glucose + oxygen -> carbon dioxide + water
  • What is the balanced equation for aerobic respiration?
    C6H12O6 + 6O2 -> 6CO2 + 6H2O
  • What is the word equation for anaerobic respiration in humans?
    Glucose -> lactic acid
  • What is the word equation for anaerobic respiration in plants?
    Glucose --> ethanol + carbon dioxide
  • How is carbon dioxide production measured in plants?
    Using germinating and boiled beans above indicator
  • What are organelles?
    Specific jobs inside cells
  • What are cells?
    Smallest unit of a living thing
  • What are tissues?
    Group of similar cells working together
  • What are organs?
    Groups of tissues working together
  • What are organ systems?
    Groups of organs working together
  • What happens during inhaling?
    Ribs move up, diaphragm contracts, intercostal muscles contract
  • What happens during exhaling?
    Ribs move down, diaphragm relaxes, intercostal muscles relax
  • What occurs during diffusion in gas exchange?
    Oxygen diffuses from alveoli into blood
  • How is the structure of alveoli adapted for gas exchange?
    High surface area, moist, thin walls, good blood supply
  • How is the concentration gradient maintained between alveoli and blood?
    Constant blood flow carries O2 away
