SYLLABUS IN BRIEF – HL IB BIOLOGY YR TWO

2015-16 DATES AND ESSENTIAL IDEAS

TOPIC 4 – ECOLOGY (summer work, in class quiz 9/11)

  • Species, communities and ecosystems. The continued survival of living organisms including humans depends on sustainable communities. (4.1)
  • Energy flow. Ecosystems require a continuous supply of energy to fuel life processes and to replace energy lost as heat. (4.2)
  • Carbon cycling. Continued availability of carbon in ecosystems depends on carbon cycling. (4.3)
  • Climate change. Concentrations of gases in the atmosphere affect climates experienced at the Earth’s surface.( 4.4)

TOPIC 3 – GENETICS –(9/9-9/25) (completing topic from yr 1)

  • Gene Modification/Biotechnology. Biologists have developed techniques for artificial manipulation of DNA, cells and organisms. (3.5)

OPTION B – BIOTECHNOLOGY & BIOINFORMATICS (9/26-11/10)

  • Microbiology: organisms in industry. Microorganisms can be used and modified to perform industrial processes. (B.1)
  • Biotechnology in agriculture. Crops can be modified to increase yields and to obtain novel products. (B.2)
  • Environmental protection. Biotechnology can be used in the prevention and mitigation of contamination from industrial, agricultural and municipal wastes. (B.3)
  • Medicine. Biotechnology can be used in the diagnosis and treatment of disease. (B.4)
  • Bioinformatics. Bioinformatics is the use of computers to analyze sequence data in biological research. (B.5)

TOPIC 9 - PLANT BIOLOGY (11/11-12/7)

  • Transport in the xylem of plants. Structure and function are correlated in the xylem of plants. (9.1)
  • Transport in the phloem of plants. Structure and function are correlated in the phloem of plants. (9.2)
  • Growth in plants. Plants adapt their growth to environmental conditions. (9.3)
  • Reproduction on plants. Reproduction in flowering plants is influenced by the biotic and abiotic environment. (9.4)

(CUMULATIVE MIDTERM REVIEW 12/8-12/14, TESTS 12/15-12/17

INTERNAL ASSESSMENT – INDEPENDENT LAB PROJECT PLANNING & DATA COLLECTION 1/4-1/29, FINAL REPORT DUE2/16 – 20% of IB GRADE )

TOPICS 6 & 11 – HUMAN/ANIMAL PHYSIOLOGY (2/1 - 4/15)

  • Digestion & absorption. The structure of the wall of the small intestine allows it to move, digest and absorb food. (6.1)
  • Gas exchange. The lungs are actively ventilated to ensure that gas exchange can occur passively. (6.4)
  • Blood system. The blood system continuously transports substances to cells and simultaneously collects waste products. (6.2)
  • Kidney & osmoregulation. All animals excrete nitrogenous waste products and some animals also balance water and solute concentrations. (11.3)
  • Defense against infectious disease. The human body has structures and processes that resist the continuous threat of invasion by pathogens. (6.3)
  • Antibody production & vaccination. Immunity is based on recognition of self and destruction of foreign material. (11.1)
  • Neurons & systems. Neurons transmit the message, synapses modulate the message. (6.5)
  • Muscles & movement. The roles of a musculoskeletal system are movement, support and protection. (11.2)
  • Hormones, homeostasis & reproduction. Hormones are used when signals need to be widely distributed. (6.6)
  • Sexual reproduction. Sexual reproduction involves the development and fusion of haploid gametes. (11.4)
