Photosynthesis
A chemical reaction that takes place inside a plant, producing food for the plant to survive.
Reactant
Substances that react together in a chemical reaction.
Product
Substances that are produced by a chemical reaction.
Carbohydrate
Compounds that are found in living things. Their molecules are made up of carbon, hydrogen and oxygen attoms.
Independent Variable
The variable that is changed during an experiment.
Dependent Variable
The variable that is measured during an experiment.
Stomata
Small holes in the undersides of leaves that allow gas exchange.
Diffusion
The movement of particles from an area of high concentration to an area of lower concentration.
Adaptations
Special features that help organisms to survive.
Respiration
A chemical reaction that happens in all living cells, it is the way that energy is released from glucose.
Aerobic Respiration
Respiration where oxygen is one of the reactants.
Anaerobic Respiration
Respiration where oxygen is not one f the reactants.
Yeast
single cell fungal organism.
Ventillation
The process of breathing.
Glucose
The sugar produced by photosynthesis and needed for respiration.
Mitochondria
The part of the cell where aerobic respiration happens.
Chloroplasts
The part of the cell where photosynthesis hapens.
Lactic Acid
The product of anaerobic respiration in humans.
Oxygen Debt
The amount of oxygen required to remove the lactic, and replace the body’s reserves of oxygen.
Light
Where the energy for photosynthesis is provided from.
Chlorophyll
Green pigment that is needed for photosynthesis.
Guard cells
Cells found either side of the stomata and control it’s opening and closing.
Xylem
Tissue that carries water and minerals from roots to leaves.
Phloem
Tissue that carries the products of photosynthesis around a plant.
Palisade Mesophyll
The water proof on the outside of a leave.
Spongy Mesophyll
Cells in a leaf that are looesly packed to allow gas exchange.
Anaerobic respiration in animals equation
Glucose = lactic acid
Anaerobic respiration equation in plants and cells
Glucose = ethanol and carbon dioxide
Aerobic respiration equation
Glucose + oxygen = carbon dioxide + water
Photosynthesis equation
Carbon dioxide + water light = glucose + oxygen
