Photosynthesis
process by which plants use the sun's energy to convert water and carbon dioxide into sugars
Cellular Respiration
process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
Chloroplast
organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy
Energy
the ability to do work or cause change
Combustion
The burning of a substance
Law of conservation of energy
the law that states that energy cannot be created or destroyed but can be changed from one form to another
Law Of Conservation of matter
states that matter is neither created nor destroyed, only changed in form
Energy Pyramid
a diagram that shows the amount of energy that moves from one feeding level to another in a food web
Carbon Cycle
the circulation and reutilization of carbon atoms especially via the process of photosynthesis and respiration.
Chlorophyll
green pigment in plants that absorbs light energy used to carry out photosynthesis
Mitochondria
powerhouse of the cell, produces energy (ATP) from oxygen and sugar(Cellular respiration)
Matter
anything that takes up space and has mass
