Photosynthesis Vocab.

Front 1

chloroplast

Back 1

found in cells inside leaves, the place where photosynthesis begins when the sun's energy falls on them

Front 2

water

Back 2

6 molecules of water combine with CO2 to help in the process of photosynthesis
light energy

Front 3

light energy

Back 3

photosynthesis needs light energy to change sun's energy into chemical energy
palisades cells

Front 4

palisades cells

Back 4

cells forming the palisades layer; they are long cells containing chloroplasts that are used for photosynthesis

Front 5

spongy cells

Back 5

loosely packed irregularly shaped cells below the palisade layer; these cells are photosynthetic

Front 6

leaves

Back 6

essential organs of most plants and use CO2, water and sunlight to carry on photosynthesis to produce glucose

Front 7

starch

Back 7

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

Front 8

sugar

Back 8

initial product of photosynthesis; main product of dark reaction

Front 9

upper epidermis

Back 9

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

Front 10

light reaction

Back 10

any of the chemical reactions in photosynthesis that depend on light; occurs within layered membranes inside the chloroplast during photosynthesis

Front 11

guard cells

Back 11

control the passage of gases into and out of the plant during light and dark phases

Front 12

carbon dioxide

Back 12

the gas taken into the leaf to help with photosynthesis; the reduction of CO2 helps to form glucose in the dark phase

Front 13

stoma

Back 13

openings located on the underside of a leaf that allow water and gases in and out during photosynthesis

Front 14

dark reaction

Back 14

occurs during photosynthesis when the hydrogen produced in the light phase is used for the reduction of CO2 to form glucose

Front 15

lower epidermis

Back 15

some photosynthesis can happen in the lower epidermis; mostly used to protect the plant from taking in too much water

Front 16

pigments

Back 16

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

Front 17

ATP

Back 17

an organic molecule used to deliver energy for life process
