This engaging lesson describes the key features of viruses and therefore explains why these microorganisms are non-cellular. The PowerPoint and accompanying resource have been designed to cover specification point 1.2 (f) of the CIE International A-level Biology specification and also includes details of HIV so that students are prepared for this lesson later in topic 10.
Details of the COVID-19 epidemic are included in the lesson to increase relevance and to help students to understand this biological topic in greater depth. They will understand that the lack of cell structures results in an non-cellular classification and the fact that it is unable to reproduce without a host is one of the additional reasons that renders it as non-living. The main focus of the lesson is the nucleic acid, the capsid and the attachment proteins that are present in these microorganisms and time is taken to explain how these structures are involved in the infection of a host cell. The lipid membrane is also introduced and links are made to the previous lessons on eukaryotic cells. The final section uses a version of BBC 1’s POINTLESS to introduce a number of viral diseases in animals and the use of a glycoprotein by HIV to attach to helper T cells is briefly introduced.

Topics 1 & 2: Cell structure & Biological molecules (CIE A-level Biology)
It's no coincidence that cell structure and biological molecules find themselves as topics 1 and 2 of the CIE A-level Biology course, because a clear understanding of their content is absolutely critical to promote success with the 17 topics that follow. Hours and hours of intricate planning has gone into the 18 lessons included in this bundle to ensure that the detailed content is relevant and can be understood and that links are made to related sections of topics 3 - 19. The lesson PowerPoints and accompanying resources contain a wide range of activities that include: * differentiated exam-style questions with clear mark schemes * directed discussion points * quiz competitions to introduce key terms and values * current understanding and prior knowledge checks Due to the detail included in these lessons, it is estimated that it will take in excess of 2 months of allocated teaching time to cover the content of the resources A number of the resources have been shared for free so these can be downloaded in order to sample the quality of the lessons

Topic 1: Cell structure (CIE A-level Biology)
As Biology is the study of living organisms which are built out of cells, a clear understanding of the topic of cell structure is critical for a student's success in A-level Biology. Intricate planning has gone into all 7 of the lessons included in this bundle and the variety of tasks will engage and motivate the students whilst the details of the following specification points in topic 1 of the CIE A-level Biology course are covered: **Topic 1.1: The microscope in cell studies** * Use an eyepiece graticule and stage micrometer to measure cells * Use of the millimetre, micrometre and nanometre * Distinguish between resolution and magnification * The use of light and electron microscopes * Calculate the actual sizes of specimens **Topic 1.2: Cells as the basic units of living organisms** * Recognise eukaryotic cell structures and outline their functions * State that ATP is produced in the mitochondria and the chloroplast and the role of this molecule in cells * The structure of a typical prokaryotic cell * The differences between eukaryotic and prokaryotic cells * The key features of viruses If you would like to sample the quality of these lessons, download the magnification and resolution lesson, the eukaryotic cell structures lesson and the viruses lesson as these have been shared for free

CIE A-level Biology Topic 1.2: Cell as the basic units of living organisms
A deep understanding of the topic of cells is crucial for the success of any A-level Biologist and these lessons not only provide the depth of detail needed at this level but also make links to the upcoming 18 topics in the CIE course. Contained within the 4 lesson PowerPoints and multiple resources that are included in this bundle are a wide range of activities to motivate and engage the students whilst they cover the content as detailed in topic 1.2 of the CIE A-level Biology specification. The majority of the resources are differentiated to allow students of differing abilities to access the work and to be challenged at all times. The following specification points are covered in this bundle: * The relationship between the structure and function of the structures of eukaryotic cells * The structure and role of ATP in cells * The structural features of prokaryotic cells * Comparing eukaryotic and prokaryotic cells * The key features of viruses as non-cellular structures If you would like to sample the quality of these lessons, then download the eukaryotic cell structures and functions and viruses lessons as these have been shared for free
