every cell, needs a continual supply of energy if it is to remain alive.
(cell, needs continual supply energy to remain alive) this energy originally comes from surprising source: sunlight. It is light energy
light energy from sun powers life on earth
Most organisms cannot use life energy directly, only one can which?
Plants
How do plants capture all energy needed?
A process called Photosynthesis
What is photosynthesis?
Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen.
Plants pass the energy needed on to other organisms in a form they can use
Photosynthesis is a chemical reaction performed only by plants
Can some bacteria photosynthesis?
only few types of bacteria
Plants use light energy to join together molecules of water (from the soil) and carbon dioxide (from the air) to make glucose.
Light energy transformed into chemical energy stored in the glucose molecules in the leaves.
Chemical emergy used by plant and other forms of life, making them run
Glucose is "bottled sunlight energy" THINK OF IT LIKE THAT
Photosynthesis involves several complex chemical
Photosynthesis word equation:
In Photosynthesis carbon diozide and water get used up, glucose and oxygen are made
Photosynthesis word equation goes from, reactants(carbon dioxide+water) converted by light energy, and chlorophyll to the products (glucose+oxygen)
Photosynthesis equation means carbon dioxide and water get used up. Whilst glucose and oxygen are made.
Light energy is not a chemical substance
Only chemical substances written on the line in a chemical eqution.
Chlorophyll under arrow because altough it is a chemical substance it is not used or made in reaction, only recyled/transfers/changes. (absorb the light-glucose, oxygen)
Sun provides heat and light radiation, plants use light in photosynthesis, not heat.
Plants use any light of the right wave length in photosynthesis (fake light, lamps, coloured too)
