Roots are superficial and extensively developed; to provide large surface area for water absorption;
Roots grow deep / long roots; to reach water table / source deep in the ground;
Succulent / fleshy stem / stem possession of water storage tissue to store water for future use / to enable them survive drought;
Possession of waxy thick cuticle to reduce transpiration rate;
Reduced leaf surface / spines / scales / leaves modified into needle-like to minimize surface area (directly exposed to sunlight) to lower rate of transpiration;
Sunken stomata / hairy stomata / hairy leaves to lower rate of transpiration;
Some xerophytes have reversed stomatal rhythm to minimize rate of transpiration;
Rolled leaves / folded leaves to minimise stomata directly exposed to sunlight to lower rate of transpiration;
Short life cycles / quick growth after rains to make use of available water quickly;
Reduced number of stomata that lower the rate of transpiration;
Some shed their leaves during dry period to reduce transpiration rate;

50cm³ of 10% glucose solution was boiled and allowed to cool. The solution was then poured into a vacuum flask and about
5cm³ of groundnut oil added to it. 10% yeast solution was introduced into the glucose solution using a pipette. A
thermometer was placed in the flask and supported with a cotton wool plug. A second flask was set up as above, but
containing cooled boiled water instead of 10% glucose solution. The temperature of each flask was recorded at the
beginning and thereafter at hourly intervals for several hours.
a) Why was a vacuum flask used in this experiment?
b) What was the purpose of the second flask?
c) Write a word equation to summarize the reaction that took place in the first flask.
d) Why was groundnut oil added to the flask?
e) Why was it necessary to boil the glucose and the water before they were poured into the flask?
