Official JAMB Biology outline · B: Form and Functions

Content

Modes of nutrition: autotrophic and heterotrophic. Types of nutrition, including holozoic nutrition in sheep and humans; parasitic nutrition in roundworms, tapeworms and Loranthus; saprophytic nutrition in Rhizopus and mushrooms; and carnivorous nutrition in sundew and bladderwort.

Objective

Compare autotrophic and heterotrophic nutrition; provide examples from flowering and non-flowering plants; differentiate holozoic, parasitic, saprophytic and carnivorous nutrition; determine the nutritional value of the organisms studied.

Content

Plant nutrition: photosynthesis and chemosynthesis; light and dark reactions of photosynthesis; the roles of light, carbon(IV) oxide and chlorophyll; starch testing as evidence of photosynthesis; mineral requirements, including macronutrients and micronutrients; deficiency symptoms of nitrogen, phosphorus and potassium.

Objective

Compare photosynthesis and chemosynthesis; differentiate light and dark reactions; determine the necessity of light, carbon(IV) oxide and chlorophyll in photosynthesis; detect starch in leaves as evidence of photosynthesis; identify plant macronutrients and micronutrients; recognize nitrogen, phosphorus and potassium deficiency symptoms.

Content

Animal nutrition: classes of food substances, including carbohydrates, proteins, fats and oils, vitamins, mineral salts and water; food tests for starch, reducing sugars, proteins, oils and fats; sources and nutritional values of food; deficiency diseases, including scurvy, rickets and kwashiorkor; balanced diet.

Objective

Identify sources of different food classes; determine the nutritional value of food; relate the importance of each food class to its deficiency diseases; explain the importance of a balanced diet; identify food types from experimental results.

Content

Mammalian teeth: structure, types and functions; comparison of human, sheep and dog dental formulae.

Objective

Describe the structure of a typical mammalian tooth; differentiate types of mammalian teeth and relate their structures to their functions; compare the dental formulae of humans, sheep and dogs.

Content

Mammalian alimentary canal and accessory organs, including the liver, pancreas and gall bladder; ingestion, digestion, absorption and assimilation; digestive enzymes and their functions.

Objective

Relate the structures of the alimentary canal and accessory organs to their functions; identify the general characteristics of digestive enzymes; associate enzymes with digestion of carbohydrates, proteins and fats; determine the end products of digestion of these food classes.
