I. McKay, et al (2012),1.IntroductionSolutions for all Life• Discuss the cell as the smallest unit of lifeSciences Grade 11 pp. 5 -• Revision of 7 living characteristics6• Ask the following questions• Answer questionsIntroduction (5min)2. W. Bezuidenhout, et al• 1. Can viruses be classified as living? (viruses do not display any of the living characteristics( 2012), Oxford Successfulsuch as metabolic activities and therefore are not cells, they are only able to reproduceLife Sciences Grade 11inside of a host cell)p 11 – 12• 2. Are virus’ cells? ( no they are acellular as they are tiny particles of genetic materialsurrounded by a protein coat)1.2 Main Body (Lesson presentation)• Individual work• Write down basic characteristics and structure of viruses into the work book• Write down a brief15 min• Viruses consist of a central core of nucleic acid either DNA or RNA.description of the• They have a capsid or protein coat around the nucleic acidstructure of viruses• Viruses have various shapes that consist of symmetrical facets• Viruses do not perform any metabolic reactions of living organisms (no cellular respiration)• Solutions for all LifeTerm 1 Page 4© Gauteng Department of Education (CAPS version)
