Process by which plants make their own food (glucose) and produce oxygen
What are chloroplasts and where are they found?
Organelles found in the leaves of green plants
What are the two main functions of chloroplasts?
To produce glucose and food energy
Why does most leaves appear green?
Because of the pigment chlorophyll found in the chloroplast
What is the primary pigment found in the chloroplast?
What is the formula for photosynthesis?
CO2 + H2O + sunlight ----> C6H12O6 + O2
What three things are used to make glucose in photosynthesis?
Light energy, carbon dioxide, and water
Where does the water come from?
From the ground
Where does the water enter the plant?
Name 3 some sources of CO2.
Living organisms, smokestacks, and car fumes
What type of energy does the plant use to convert CO2 and H2O into sugar?
What is produced in photosynthesis?
Glucose and Oxygen
What is the glucose used for?
Energy and growth
What is the oxygen used for?
For living organisms to breathe
Photosynthesis in words
Carbon dioxide and water combine with sunlight to create oxygen and glucose.
Describe, using scientific terms, how plants turn sunlight into energy. Make sure to refer to the chemical equation to photosynthesis and discus the reactants and products.
Plants convert sunlight into usable energy through the process of photosynthesis. Light energy from the photons strikes the chlorophyll in the leaves which causes a chemical reaction between the chlorophyll carbon dioxide and water creating C6H12O6 or sugar. The photosynthesis equation is 6CO2+CH20----C6H12O6+6O2 (the reactions are CO2+H20 and the products are C6H12O6+O2.
What process happens in the mitochondria?
They break down nutrients through cellular respiration to release energy for the cell to use.
What is the purpose of the process in #1 (what does it create)?
Energy is released for the cell to use.
Some organisms perform photosynthesis to produce energy. Other organisms cannot do photosynthesis. What can they do in order to generate energy?
They must eat plants and other animals in order to gain energy.
What is the purpose of cellular respiration?
Cellular respiration uses oxygen to release the energy captured through photosynthesis to be used by organisms to maintain life.
What happens to carbohydrates during cellular respiration?
They are broken down into CO2 and H20 and releasing energy.
What is the chemical energy in the cell called?
ATP stands for
What is one product of cellular respiration?
Oxygen is a what of respiration?
Cellular respiration equation
Cellular respiration processes
The Krebs cycle, and oxidative phosphorylation. Each of these occurs in a specific region of the cell.
Where does cellular respiration occur?
•Glycolysis occurs in the cytosol. •The Krebs cycle takes place in the matrix of the mitochondria. •Oxidative phosphorylation via the electron transport chain is carried out on the inner mitochondrial membrane.
