found in cells inside leaves, the place where photosynthesis begins when the sun's energy falls on them
6 molecules of water combine with CO2 to help in the process of photosynthesis
light energy
light energy
photosynthesis needs light energy to change sun's energy into chemical energy
palisades cells
palisades cells
cells forming the palisades layer; they are long cells containing chloroplasts that are used for photosynthesis
spongy cells
loosely packed irregularly shaped cells below the palisade layer; these cells are photosynthetic
essential organs of most plants and use CO2, water and sunlight to carry on photosynthesis to produce glucose
CO2 and water combine to make starch during photosynthesis; the food in plants is starch, which provides almost 70% of the world's food supply
initial product of photosynthesis; main product of dark reaction
upper epidermis
the outer protective layer of the leaf; does not contain chlorophyll and can't make food; allows light to pass through to the food-making cells below it
light reaction
any of the chemical reactions in photosynthesis that depend on light; occurs within layered membranes inside the chloroplast during photosynthesis
guard cells
control the passage of gases into and out of the plant during light and dark phases
carbon dioxide
the gas taken into the leaf to help with photosynthesis; the reduction of CO2 helps to form glucose in the dark phase
openings located on the underside of a leaf that allow water and gases in and out during photosynthesis
dark reaction
occurs during photosynthesis when the hydrogen produced in the light phase is used for the reduction of CO2 to form glucose
lower epidermis
some photosynthesis can happen in the lower epidermis; mostly used to protect the plant from taking in too much water
any natural substance present in and coloring the tissue of an organism; the pigmentation of a leaf during photosynthesis turn green showing that chlorophyll is present
an organic molecule used to deliver energy for life process
