Question 8 of 54

1

Select from the dropdown lists to complete the text.

In leaves, carbon dioxide diffuses into the air spaces within the leaf and then into the cells in which ( photosynthesis, respiration, replication ) happens. The cell walls increase ( surface area, size, temperature ) so carbon dioxide is more likely to get through. The bottom of the leaf is covered in ( stomata, pigmented green colours, stems that act as veins ) which the carbon dioxide diffuses through. Leaves are flat to ( increase, decrease, maintain ) this exchange surface area. Guard cells close the stomata if water is being ( lost too quickly, absorbed too quickly, lost too slowly ). ( Oxygen and water vapour, Carbon dioxide and oxygen, Glucose and water ) diffuse out through the stomata. Water vapour evaporates from leaf cells and escapes by diffusion.
