Assessment Specifications These assessment specifications remain draft subject to registration of the standards. General information Domain Biology Level 1 Mode of Assessment Written examination For Year 2011 This document contains the assessment specifications for Achievement Standards: 90927, 90928, 90929 Format for the assessment for all achievement standards Within each paper all questions will provide opportunity for all grades of performance Achievement, Achievement with Merit, and Achievement with Excellence; there are no standalone questions for lower achievement grades. Candidates should attempt all questions. Diagrams may be used to provide evidence where appropriate. Specific Information for individual External Achievement Standards Achievement Standard Number 90927 Title Demonstrate understanding of biological ideas relating to micro-organisms Version: Number of Credits: 4 1 Special notes This achievement standard assesses biological ideas that relate to micro-organisms selected from bacteria, fungi and viruses. Factors that affect the life processes of micro-organisms include: moisture, temperature, oxygen availability, presence of suitable nutrients, and host species, competitors related to antibiotic action and resistance; also, why viruses cannot be considered living (only reproduce using host cells and do not grow, feed, produce energy or excrete). Achievement Standard Number 90928 Title Demonstrate understanding of biological ideas relating to the life cycle of flowering plants Version: 1 Number of Credits: 4 Special notes This achievement standard requires knowledge of flowering plants (Angiosperms), with a focus on flowers, leaves, roots, and dicotyledonous seeds and stems. Asexual reproduction requires familiarity with different methods of asexual reproduction including but not limited to cuttings, tubers, rhizomes, runners, bulbs. Sexual reproduction includes: • • • • wind pollinated flower structure compared to insect pollinated flowers, relating structure to function steps involved from pollination to fertilisation structure of dicotyledon seeds relating each structure to its function methods of seed dispersal. Germination and growth includes: • • • • • • germination stages environmental factors affecting germination growth in meristematic tissue primary growth in stems and roots secondary growth the importance of nutrients as they relate to growth and photosynthesis. Photosynthesis includes: • • • structure and function of a leaf raw materials and products factors that affect the rate of photosynthesis: light intensity, temperature, amount of chlorophyll, CO2 concentration. Candidates should be familiar with basic practical work relating to photosynthesis. Achievement Standard Number 90929 Title Version: 1 Special notes Demonstrate understanding of biological ideas relating to a mammal as a consumer Number of Credits: 3 Structural components of the digestive system include: • • • • • • • • • • • • • • • • buccal cavity (mouth - including structure of a generalised tooth) salivary glands oesophagus stomach duodenum bile duct liver gall bladder pancreas pancreatic duct ileum caecum appendix colon rectum anus. Life processes related to a mammal as a consumer includes: Processing food • • • • • • ingestion digestion peristalsis absorption assimilation egestion Transport of products of digestion is limited to the function of the circulatory system, and the basic structures are limited to the heart (names of structures within the organ are not required), veins, arteries and capillaries. Use of food at the cell level is limited to aerobic respiration (including raw materials and products), and the basic structures are limited to the lungs (names of structures within the organ are not required). Candidates may be asked to relate processing of food, circulation and respiration to each other and to the overall survival of the mammal.
