Hint: 4 choices Increase temp Increase humidity Increase light intensity Increase surface area Increase wind 2/9 How is the upper epidermis adapted for photosynthesis? its transparent and allows sunlight to be absorbed Has a lot of chlorophyll to increase photosynthesis Has a lot of air spaces for gaseous exchange 3/9 What is the structure of the xylem? Strong thick cell wall, and dead cells Alive cells thin and hollow 4/9 Deficiencies of little phosphurus Yellow leaves and poor flower growth discoloured leaves and poor growth discoloured leaves and poor root growth 5/9 How is the spongy mesophyl adapted for photosynthesis Has a lot of chlorophyll to increase photosynthesis Has a lot of air spaces for gaseous exchange Its transparent so allows alot of sunlight in 6/9 Deficiencies of little potassium discoloured leaves and poor root growth discoloured leaves and poor flower growth Yellow leaves and poor flower growth 7/9 Deficiencies of little nitrogen Yellow leaves and poor growth Discoloured leaves and poor growth Yellow leaves and poor flower growth 8/9 What is the structure of the phloem? thin and hollow, living cells dead cells strong, thick cell walls 9/9 Deficiencies of little magnesium Yellow leaves Discoloured leaves Poor root growth
