(b) Describe briefly the generalised structure of a tooth in animals.
(c) List three food substances that plants manufacture from glucose.
(d) Make a diagram, 6 cm to 8 cm long of an experimental set-up to show that oxygen is produced during photosynthesis.
Explanation
(a) Dentition In Animals: Is the type/shapes, number, and arrangement of teeth in the mouth/jaws of animals
(b) Description of the Generalised Structure of a Tooth in Animals: -The tooth is made up of a crown. neck and root. -The visible part of the tooth in the crown. -And is covered by the hardest substances/enamel -The neck of the tooth is surrounded by the gum. -While the root is embedded in the jawbone. -Beneath the enamel is the hard dentine. -Which forms the bulk of the tooth in the pulp cavity. -Containing sensory endings of nerves/blood capillaries. -The cement/periodontal membrane covers the root of the tooth in the jawbone.
(c) Food Substances that Plants Manufacture from Glucose:-Sucrose/maltose-Starch -Cellulose -Oil-Proteins
(d) Diagram of an Experiment that Shows that Oxygen is Produced During Photosynthesis
