The WORD EQUATION and CHEMICAL EQUATION for PHOTOSYNTHESIS is…
CARBON DIOXIDE and WATER (in the presence of SUNLIGHT and CHLOROPHYLL) yields GLUCOSE and OXYGEN
6CO2+ 6H2O (in the presence of SUNLIGHT and CHLOROPHYLL) yields C6H12O6 + 6O2
The WORD EQUATION and CHEMICAL EQUATION for CELLULAR RESPIRATION is…
GLUCOSE and OXYGEN (with ATP) yields CARBON DIOXIDE and WATER
C6H12O6 + 6O2 (with ATP) 6CO2 + 6H20
PHOTOSYNTHESIS is an ______________ process
ENDERGONIC
CELLULAR RESPIRATION is an ____________ process
EXERGONIC
In Photosynthesis, where does Carbon Dioxide enter the plant cells?
Carbon Dioxide enters the plant cells through the STOMATA
In Photosynthesis, where does WATER enter the plant cells?
Water enters the plant cells from the ROOTS
What is GLUCOSE stored as in PLANT CELLS?
Glucose is stored as STARCH in plant cells
When WATER (6H20) is split during PHOTOSYNTHESIS, what happens to the HYDROGEN and OXYGEN molecules?
The HYDROGEN MOLECULES help to form GLUCOSE, whilst the OXYGEN MOLECULE is released into the atmosphere.
Where does CELLULAR/AEROBIC RESPIRATION take place?
Cellular Respiration takes place in the CYTOSOL and the MITOCHONDRIA
PHOTOSYNTHESIS can occur in ______________ , ___________ and ______________
Plants, Algae and Photosynthetic Bacteria
What is the role of XYLEM in a plant?
XYLEM transports WATER and DISSOLVED SUBSTANCES from SOIL TO LEAVES (upwards)
What is the role of PHLOEM in plants?
PHLOEM transports NUTRIENTS both UPWARDS AND DOWNWARDS
What is TRANSPIRATION?
Transpiration is the MOVEMENT OF WATER FROM SOIL TO LEAVES until it is RELEASED INTO THE ATMOSPHERE.
What is TRANSLOCATION?
Translocation is the movement of WATER AND OTHER SUBSTANCES BOTH UPWARD AND DOWNWARD in plants
Anaerobic Respiration involves FERMENTATION. What is Fermentation?
FERMENTATION is the BREAKDOWN of substances WITHOUT OXYGEN
In Human Cells, how does Anaerobic Respiration work and what is it called?
In HUMAN CELLS, glucose is broken down into pyruvate, which is then broken down into LACTIC ACID. This is called LACTIC ACID FERMENTATION
What is Anaerobic Respiration called in Yeast Cells?
In Yeast cells, an alcohol (ETHANOL) is produced. It is called ALCOHOLIC FERMENTATION
Some organisms can perform both AEROBIC and ANAEROBIC RESPIRATION. What are these organisms called and what is an example of one?
These are called FACULTATIVE ANAEROBES and HUMAN MUSCLE CELLS are an example
