where is palisade mesophyll found?

Answer 36

between the upper and lower surface of a leaf

Question 37

what does the palisade mesophyll tissue do and how?

Answer 37

perform photosynthesis | arranged in lines; tops of cells meet sunlight head on; light travels throughout cell, encountering chloroplasts

Answer 38

below palisade cells | between the upper and lower surface of a leaf

Question 39

what does spongy mesophyll do?

Answer 39

loosely packed to form a network of open spaces containing gases needed containing gases needed or produced by photosynthesis (water vapour, oxygen, carbon dioxide)

Question 40

Answer 40

lower surface of a leaf

Question 41

what does stomata do?

Answer 41

change shape to control opening and closing of pores in the leaf = "guard cells"
