photosynthesis

Question 1

what is the balanced chemical equation of photosynthesis

Answer 1

6CO(2) + 6H(2)O –> C(6)H(12)O(6) + ^O(2)

Question 2

what are some mineral ions used by plants?

Answer 2

nitrates - required to make amino acids
magnesium - required to make chlorophyll
[phosphates - required to make nucleic acid]

Question 3

what are the limiting factors of photosynthesis?

Answer 3

carbon dioxide concentration, temperature, light intensity

Question 4

how do plants maximise absorption of sunlight

Answer 4

large surface area and thin

Question 5

how is the upper epidermis adapted?

Answer 5

transparent to allow light to get to mesophyll

Question 6

describe the palisades and its uses

Answer 6

long and thin cells that are tightly packed, contains a lot o chloroplasts
main site of respiration

Question 7

what do the stomata do?

Answer 7

they allow gasses to diffuse in the air spaces of the eaves which creates a short diffusion distance

Question 8

what does the xylem do?

Answer 8

transports water from the roots to the leaves, which shortens the diffusion distance of water

Question 9

what does the phloem vessel do?

Answer 9

transports sugars produced in photosynthesis to different part of the plant
