what is photosynthesis
It is when energy is transferred from the environment to the leaves of a plant
what part of the leaf absorbs the light energy
chloroplasts
what is the photosynthesis equation
6 CO2 + 6 H2O = C6H12O6 + 6 O2
what are the factors that effect the rate of photosynthesis
temperature, carbon dioxide concentration and light intensity
What is cellular respiration
The reaction that is used for energy needed is all living processes
Is cellular respiration endothermic or exothermic
Exothermic
What are the 2 types of respiration
Aerobic and anaerobic
What is fermentation
Anaerobic respiration in yeast cells
What is the by product of anaerobic exercise
Lactic acid
What is the function of the nervous system
Enables humans to react to the surroundings
How is the nervous system organised
Stimulus, receptor, coordinator, effector, response
What are the factors that effect the nervous system
Tiredness, distractions, caffeine, alcohol
What is homeostasis
The regulation of internal conditions
What does homeostasis control
