plant nutrition and transport

Question 1

what is the importance of photosynthesis

Answer 1

converting light energy into chemical energy to provide for the autotroph (plants)

Question 2

why do plants need
- mineral ions
- magnesium ions
- nitrate ions

Answer 2

mineral ions - growth
magnesium ions - chlorophyll
nitrate ions - amino acids

Question 3

how is the structure of the leaf adapted for gas exchange

Answer 3

• stomata allows for gas to enter and exit
• spongy mesophyll has air pockets to allow for gas exchange

Question 4

role of diffusion in gas exchange

Answer 4

gas exchange between oxygen and co2 is achieved by diffusion

Question 5

gas exchange in photosynthesis and respiration

Answer 5

gas exchange plays the same role in both of these processes just inverted
