A worksheet aimed at advanced level biology students as a quick review of the main details of the fluid mosaic structure of cell membranes. There is a clear diagram that requires labelling along with follow-up questions on the function of each component.

A resource aimed at GCSE (14-16 year old) biology students, this worksheet provides a labelling task for animal and plant cells as viewed down the light microscope along with mix and match task relating to the function of each organelle. The task also includes some extension questions on the nature of mitochondria for students to research (perhaps as a homework exercise). The resource is tailored to the Hodder AQA 9-1 Biology textbook but the page references in the worksheet could easily be adapted to any other textbook reference.

A resource aimed at advanced level biology students, this worksheet provides a comparison table for mitosis, meiosis I and meiosis II. Students often confuse the events of these processes, particularly the movement of chromosomes and so it is a useful exercise to clarify which events happen where. Keywords: mitosis, meiosis, chromosomes, chromatid, diploid, haploid, centriole, centromere

An activity aimed at GCSE biology (age 14-16) students on the topic of stem cells. The activity includes a powerpoint presentation and a questionnaire word document. The powerpoint can be printed out on separate sheets of A4 and posted around the classroom for students to find - each slide has a suitable image together with clear explanatory text. The questionnaire matches the slides and so students can then match the answer to the relevant question. In terms of delivery, students can be paired up after they complete the activity and asked to verbally test each other on their knowledge of stem cells, checking that the information gathered has been understood. This can then lead into a whole class teacher-led discussion using the powerpoint slides to summarise the topic and check responses to each question. The activity includes coverage of the nature of stem cells, embryonic versus adult stem cells, IVF, uses of stem cells, ethical issues, tissue culture and medical treatments that are possible using stem cell therapy.

A worksheet aimed at A-Level Biology students that asks students to apply their knowledge of ecology to that of conservation. The worksheet focuses on how our knowledge of succession can be used to conserve moorland and native bird species in the UK. Full answers are provided on the second page of the worksheet. Key words: Succession, conservation, moorland, birds, ecology, ecosystem, habitat

Suitable for A-Level Biology, this worksheet provides a series of questions suitable for use as a plenary, on the causes of lactose intolerance. The questions make synoptic links with other topics including biological molecules and enzymes. Key words: Lactose, enzyme, hydrolysis, milk, glucose, galactose

A worksheet aimed at A-Level Biology students that provides four questions to practice their knowledge of the technique of mark-release-recapture.
