Photosynthesis

Question 1

reactants

Answer 1

the inputs of a chemical reaction. Location on the left side of a chemical equation

Question 2

products

Answer 2

the outputs of a chemical reaction. located on the right side of a chemical equation

Question 3

xylem

Answer 3

carries water and minerals through a plant

Question 3

stomata

Answer 3

small openings on the underside of a leaf through which oxygen and carbon dioxide can move. where gas exchange occurs in a plant

Question 4

phloem

Answer 4

carries food (glucose) through a plant

Question 4

chlorophyll

Answer 4

pigment which fills chloroplast. this pigment abosrbs sunlight

Question 5

chloroplast

Answer 5

location inside of a plant cell where the process photosynthesis takes place occurs

Question 6

photosyntesis

Answer 6

conversion of light energy from the sun into chemical energy (stored in glucose)

Question 7

oxygen

Answer 7

chemical that plants release

Question 8

carbon dioxide

Answer 8

a gas that plants take in (reactant) through small holes in their leaves for the process of photosynthesis

Question 9

what are the three main ingredients/reactants of photosythesis

Answer 9

water, sunlight, carbon dioxide

Question 10

leaves

Answer 10

these open up to collect sunlight and contain the chloroplasts which produce food

Question 11

stem

Answer 11

supporting structure of a plant that connects roots and leaves and carries water and nutrients between them

Question 12

carbohydrates

Answer 12

chains of glucose

Question 12

-ose

Answer 12

the suffix for all sugars

Question 13

upper epidermis layer

Answer 13

a single layer of clear cells that allow light to pas through and prevents the loss of water

Question 13

petiole

Answer 13

the stalk of a leaf, which joins the leaf to a node of the system

Question 14

cuticle

Answer 14

the waxy, waterproof layer that covers the leaves and stems of most plants

Question 14

spongy layer

Answer 14

loosely-packed chloroplast-bearing cells in the interior of leaves; surrounded by air space

Question 15

stomata

Answer 15

small openings on the underside of a leaf through which oxygen and carbon dioxide can move

Question 16

guard cells

Answer 16

the two cells that flank the stomatal pore and regulate the opening and closing of the pore

Question 17

grana

Answer 17

stacks of thylakoids

Question 17

stroma

Answer 17

fluid portion of the chloroplast; outside of the thylakoid

Question 18

chlorophyll

Answer 18

green pigment in plants that absorbs light energy used to carry out photosynthesis

Question 19

calvin cycle

Answer 19

light-independent reactions of photosythesis in which energy from ATP and NADPH is used to build high-energy compounds usch as sugar

Question 20

light-dependent reactions

Answer 20

reactions of photosythesis that use enrgy from light to produce ATP and NADPH

Question 20

what is NADPH

Answer 20

an electron carrier

Question 21

what are electrons

Answer 21

energy

Question 21

endergonic

Answer 21

energy "created" using this part doesn't require light

Question 21

exergonic

Answer 21

light-dependent releases energy; energy is a result of this reaction

Question 21

steps of a calvin cycle

Answer 21

step 1 - CO2 fixation - CO2 diffuses into the stroma and combines with RuBP (ribulose bisphosphate) with the help of enzymes step 2 - six carbon molecules are unstavle and split into 3-carbon compounds step 3 - one G3P molecule leaves the Calvin cycle and is used to make organic compounds (glucose chain) step 4 - the remaining G3P molecules are converted back into the 5-carbon molecules RuBP and re-enter the Calvin cycle
