photosynthesis

Question 1

palisade mesophyll

Answer 1

layer of the leaf where photosynthesis occurs most because of the direct access to sunllight - palisade: column

Question 2

spongy mesophyll

Answer 2

other layer of the leaf where photosynthesis occurs, but not as much as palisade mesophyll since it doesn’t get as much direct access to sunlight.

Question 3

xylem

Answer 3

part of the vascular bundle/vein, transports H20 + minerals

Question 4

phloem

Answer 4

part of the vascular bundle/vein, transports food/glucose

Question 5

cuticle

Answer 5

waxy covering of the leaf to prevent evaporation of H20/dehydration

Question 6

epidermis

Answer 6

layer between cuticle and palisade mesophyll - another protective layer

Question 7

stoma(ta)/guard cell

Answer 7

open + close:

• gas exchange (O2 out, CO2 in)
• H2O leaves (transpiration)

Question 8

which parts of the leaf do photosynthesis?

Answer 8

palisade mesophyll + spongy mesophyll

Question 9

equation for photosynthesis

Answer 9

6H2O + 6CO2 + light energy –> C6H12O6 + 6O2

Question 10

what is the pigment that absorbs light energy + where is it?

Answer 10

chlorophyll, located within the chloroplast, within the thylakoids

Question 11

stroma

Answer 11

space inside the chloroplast

Question 12

grana

Answer 12

multiple granums

Question 13

granum

Answer 13

stack of thylakoids

Question 14

thylakoid

Answer 14

singular disk that forms the stacked granum + multiple grana

Question 15

what color does chlorophyll best absorb/least reflect?

Answer 15

red + blue

Question 16

what color does chlorophyll least absorb/most reflect? why are plants green?

Answer 16

green - plants reflect green light giving them a green color

Question 17

what undergoes photosynthesis?

Answer 17

autotrophs - be careful not to say plants, that doesn’t include bacteria that photosynthesize, etc.

Question 18

main purpose of photosynthesis?

Answer 18

to make food for the plant

Question 19

step 1

Answer 19

plants take in CO2 through the stomata + absorb water through the roots
