Question 2

epidermal cells

Answer 2

are transparent to allow light to penetrate

Question 3

xylem

Answer 3

transports nutrients and food

Question 4

phloem

Answer 4

transports water

Question 5

palisade parenchyma

Answer 5

contains large numbers of chloroplasts situated on the axadial surface for maximum light absorption (densely packed to facilitate diffusion

Question 6

waxy cuticle

Answer 6

lipid later covering the epidermis of leaves of all plants reducing transpiration

Question 7

axadial

Answer 7

upper smooth surface

Question 8

abaxial

Answer 8

lower rough surface

Question 9

stomata

Answer 9

contains guard cells and chloroplasts

Question 10

guard cells

Answer 10

play a role in the opening and closing of the stomata, to absorb and release gas

Question 11

spongy parenchyma

Answer 11

loosely arranged cells with large intercellular space (for gaseous exchange to occur)

Question 12

vascular bundles/veins

Answer 12

large amounts run through the leaves providing support and most importantly transports of water and dissolved salts
