Photosynthesis & Carbon Cycle
Chloroplast
Where in plant cells does photosynthesis occur?
Mass per unit volume.
What is density?
Protons, neurtons and electrons
What are the subatomic particles that make up an atom?
The four components of the excretory system.
Kidney, ureter, urethra, bladder.
Number of vibrations per second
What is frequency?
Carbon dioxide + water --> glucose + oxygen, Light and chlorophyll are necessary for this reaction to occur.
State the word equation for photosynthesis and the two substances necessary for the chemical reaction to occur.
Heat is the total kinetic energy of particles, temperature is the average kinetic energy of particles.
How is heat different from temperature?
The order of the reactivity series.
Potassium (K), Sodium (Na), Calcium (Ca), Magnesium (Mg), Aluminium (Al), Zinc (Zn), Iron (Fe), Copper (Cu), Silver (Ag), Gold (Au)
To filter the blood
What is the function of the kidney?
A peak meets a peak or trough meets a trough
What is sound reinforcement?
To make chlorophyll
Why do plants need magnesium to photosynthesise?
Heat moves spontaneously from regions of higher temperature to lower temperature, aligning with the principle of heat dissipation.
Why does thermal energy always flow from hot to cold?
What type of bond is formed by sharing electrons?
A reproductive cell - sperm and egg.
What is a gamete?
Two sound waves from nearby speakers in phase combine to create a louder spot
Photosynthesis, respiration, nutrition/feeding, decomposition and combustion
What are the five key processes in the carbon cycle?
Heating makes particles move faster and spread apart, reducing density. Warmer, less dense regions rise, while cooler, denser regions sink
What are convection currents in liquids and gases?
When one atom transfers electrons to another, creating positive and negative ions that attract each other.
Ionic Bond
To transport water.
What is the function of the xylem in a plant?
The louder the sound is.
What happens if the amplitude increases?
Release CO2 into the atmosphere when burned, contributing to the greenhouse effect.
What role do fossil fuels play in contributing to the increases in CO2 in the atmosphere?
When particles with high energy escape from a liquid’s surface as vapor, they carry energy away, reducing the average energy of the remaining particles and thus lowering temperature.
What is cooling by evaporation?
An atom that has gained or lost one or more electrons
What is an ion?
The liver
Where is urea formed?
The horizontal distance between two successive peaks (or troughs)
What is the wavelength of a sound?
