Energy is the capacity to do work, cellular work includes building complex molecules and moving substances in and out of the cell.
Chemical Energy: potential energy stored in the bonds of biological molecules (Food)
Potential Energy: stored energy (Food)
Kinetic Energy: the energy of motion or movement, (muscle movement, digestion breaks down food and releases energy)
Heat: the kinetic energy generated by random movements of molecules or atoms (transfer of energy from food to muscle to environment
Autotroph: plants are autotrophs, they capture energy from the sunlight through photosynthesis
Plants take sunlight and make sugars, glucose sugar, chemical energy.
The glucose sugar goes to:
Chloroplast: the organelle in the plant cell where photosynthesis occurs
Sunlight has Photons: packets of light energy, each with a specific wavelength and quantity of energy
A photon is both a wave and a particle
Light Energy: the energy of the electromagnetic spectrum of radiation
Chlorophyll: The pigment present in the green parts of plants that absorbs photos of light energy during photosynthesis
ATP, Adenosinetriphosphate: The molecules that cells use to power energy-requiring functions
Carbon Fixation: the conversion of inorganic carbon CO2 into organic forms, sugars
Thylakoid: where light dependent reactions happen, Calvin Cycle, 2:29 in video
an enzyme present in plant chloroplasts, involved in fixing atmospheric carbon dioxide during photosynthesis and in oxygenation of the resulting compound during photorespiration
Protist: is any eukaryotic organism (one with cells containing a nucleus) that is not an animal, plant or fungus
The base of the food web
Diatoms are Phytoplankton, a single-celled alga that has a cell wall of silica. Many kinds are planktonic, and extensive fossil deposits have been found
Algae produce biofuel
Red Tide: some species of algae can be toxic and reproduce too quickly.
Sometimes nitrogen from fertilizers used in agricultural fields can promote rapid growth of algae, we could filter this algae out of the water and let it dry, then use it as fertilizer.
It is good for us to eat
