Photosynthesis
whats photosynthesis?
a chemical process that uses sunlight to convert water and carbon dioxide into oxygen and energy in the form of sugar
What is radiant energy?
Radiant energy refers to energy transmitted through electromagnetic waves
What is a product?
the substance or substances formed as a result of a chemical reaction
What are the reactants in a given chemical reaction?
the starting materials or substances that are present at the beginning of the reaction
What is thermal energy?
the energy in an object or substance that comes from the movement of its molecules and atoms
What are the three main ingredients needed for photosynthesis?
co2, water, and sunlight
How does radiant energy travel?
Radiant energy travels through space as electromagnetic waves,
What are the properties of a product?
size, color, component,
Where are the reactants located in a chemical equation?
on the left side of the arrow
How is temperature related to thermal energy?
Temperature is a measure of the average kinetic energy of particles within a substance, while thermal energy is the total kinetic energy of all the particles in that substance
What is the primary product of photosynthesis?
glucose
a few examples of radiant energy?
How can we identify the product formed?
Products are always written on the right side of the arrow (coming out)
What happens to the chemical bonds of reactants during a reaction?
the chemical bonds of the reactants are broken to allow the atoms to rearrange and form new bonds
What are the three ways heat can be transferred?
conduction, convection, and radiation
what role does sunlight play in photosynthesis?
primary energy source
How does the sun provide radiant energy to Earth?
nuclear fusion
What factors affect the amount of product produced?
land (natural resources), labor (people working), capital (machinery and tools), and entrepreneurship (the business leadership
the reactants are always the substances written on the left side of the arrow
in a chemical equation, the reactants are always written on the left side of the arrow,
in a freezer, how can thermal energy be transferred through the insulating material at a slow rate?
using materials with low thermal conductivity
Where in a plant cell does photosynthesis occur?
the chloroplast
How do we use radiant energy in everyday life?
cooking with microwaves
Can we predict what the product will be based on the reactants involved?
Yes, to a significant extent, you can predict the products of a chemical reaction based on the reactants involved
What is a limiting reactant?
a reactant in a chemical reaction that is used up first, limiting the amount of product that can be formed
how does radiation work?
damages cells by destroying their genetic material
