Question 1 Report
Fig. 1 shows the front teeth and cheek teeth of a grazing rabbit skull found by a wildlife ranger. The ranger compared the teeth with the food eaten by the rabbit. Rabbits cut plant stems with incisors and then grind leaves before swallowing. Most cellulose in a leaf cannot be digested by human enzymes, but microorganisms in a rabbit's gut help process some plant material.
(a) Describe how the cheek teeth shown are suited to the rabbit's food. [2]
(b) What is the main function of the incisors? [1]
(c) Give the name of the carbohydrate that forms much of a plant cell wall. [1]
Answer Details
(a) The cheek teeth have broad, flat surfaces. These surfaces are suited to crushing and grinding leaves and stems before swallowing. [2]
(b) Incisors are used for cutting or biting off plant material. [1]
(c) The carbohydrate forming much of a plant cell wall is cellulose. [1]
