Vocabulary
The process of making food in a plant is called _________________.
Photosynthesis
True or False? Water is a reactant in the photosynthetic process.
True
H2O
Water
What parts of plants absorbs water?
Roots
Carbohydrates are forms of ____________.
Sugar
The green pigment located in the chloroplast that traps the energy from the sun is called ______________________.
Chlorophyll
True or False? Glucose is a reactant of photosynthesis.
False, it is a product
CO2
Chloroplast
Who goes through the process of photosynthesis?
Plants (Producers) and some bacteria
The source of energy for all living things on earth
The Sun
True or False? Carbon Dioxide is a product of cellular respiration
true, because animals breathe out carbon dioxide.
C6H12O6
Glucose
How do plants get the hydrogen and oxygen needed to build carbohydrates?
Through the water they take into their roots.
Is Photosynthesis a chemical or physical change? Explain.
Photosynthesis is a chemical reaction because it begins with molecules of Carbon dioxide and water and when light is added the molecules break apart to rearrange into new molecules of glucose (sugar) and oxygen.
Cell Wall
False, they are products of photosynthesis.
6O2 + 6H2O + Sunlight ---> C6H12O6 + 6O2
Photosynthesis Formula
True or False? Plants have mitochondria to break down glucose into energy.
True
In the process of photosynthesis is mass/matter conserved? Explain and give reasoning.
In the formula for photosynthesis is mass/matter is conserved because the equation says that six carbon dioxide molecules combine with six water molecules to form one sugar molecule and six molecules of oxygen. If you added up all the carbon, hydrogen, and oxygen atoms on either side of the equation, the sums would be equal; matter is conserved in this chemical change.
an organism that is composed of more than one cell.
Multicellular
This reactant of photosynthesis enters the leaves and is captured by pigments in the chloroplasts.
Sunlight
02
Oxygen
True or False? Plants give off the carbon dioxide that animals need to break down carbohydrates for energy and animals give off oxygen for plants.
False, plants give animals carbohydrates for food and give off the oxygen that animals need to break down the carbohydrates.
What molecule do we has humans (and all other animals)exhale?
Carbon Dioxide
