Question 5

what is transpiration?

Answer 5

the loss of water vapour thru leaves, stems, and other (above ground) parts of plant

Question 6

transpiration is the consequence of…

Answer 6

gas exchange in the leaf

Question 7

where does transpiration occur through

Answer 7

mainly through open stomata

Question 8

how is transpirtation connected to photosynthesis

Answer 8

A tension is created in the plant due to transpiration and this acts as a driving force for the uptake of water from the soil and the movement of water to the shoots.
water required by photosynthesis

Question 9

adaptations of leaves for gas exchange (2)

Answer 9

1. stomata
   tiny pores, opening and closing controlled by 2 guard cells
2. lower tissue layer (spongy mesophyll)
   provides large surface area and moist surface neccesary for gas exchange
