nutrition in plants

Question 1

what are the factors affecting the rate of photosynthesis?

Answer 1

1. light intensity
2. concentration of carbon dioxide
3. temperature

Question 2

what is the equation for photosynthesis?

Answer 2

carbon dioxide + water –> glucose + oxygen

( write chlorophyll and sunlight on top of arrow )

Question 3

what is the definition of photosynthesis?

Answer 3

photosynthesis is the process in which light energy absorbed by chlorophyll is converted to chemical energy

Question 4

what happens to the glucose that is formed during photosynthesis?

Answer 4

glucose is either used immediately or stored

Question 5

why is photosynthesis important?

Answer 5

1. makes chemical energy available to animals and other organisms
2. removes carbon dioxide and provides oxygen
3. energy is stored in fossil fuels through photosynthesis

Question 6

adaptation of lamina

Answer 6

large flat surface –> obtain maximum amount of sunlight for photosynthesis

Question 7

petiole (adaptation)

Answer 7

hold leaf in position –> absorb maximum light energy

Question 8

waxy cuticle on upper and lower epidermis (adaptation)

Answer 8

reduces water loss through evaporation from the leaf; transparent for light to enter the leaf

Question 9

more chloroplasts in upper palisade tissue

Answer 9

more light energy can be absorbed near the leaf surface

Question 10

interconnecting system of air spaces in the spongy mesophyll

Answer 10

allows rapid diffusion of co2 and o2 into and out of mesophyll cells
