Plants/leafs/Photosynthesis

Question 1

uses of glucose

Answer 1

• respiration
• stored as starch

Question 2

process that takes place in leaf to produce (photosynthesis)

Answer 2

reactants water and carbon dioxide are used by the leaf with sufficient amount of light energy to produce the products oxygen and glucose

Question 3

what does the stomata do?

Answer 3

allows carbon dioxide to diffuse into the leaf

Question 4

why are leaves thin

Answer 4

so C02 does not have far to diffuse into the leaf (so its quicker)

Question 5

why do leaves have a large surface area

Answer 5

large surface area for absorption of sunlight

Question 6

why do leaves have large air spaces between cells

Answer 6

to allow gas exchange ( easy passage for c02)

Question 7

why are the palisade cells in a leaf arranged length way

Answer 7

exposes the larger surface area to carbon dioxide

Question 8

what is translocation

Answer 8

movement of food (such as glucose and sucrose) from the leaves to the rest of the plant

Question 9

whats the job of the XYLEM

Answer 9

to transport water and solutes from the roots to the leaves

Question 10

what does the phleym do

Answer 10

transports glucose and sucrose from leaves to the rest of the plant

Question 11

adaptations of xylem

Answer 11

streghtened by lignin
made of dead cells

Question 12

adaptations of phleym

Answer 12

• elongated living cells
• small pores to allow stuff to flow through

Question 13

what is transpiration

Answer 13

loss of water from plants by evaporation
