A resource aimed at advanced biology students, this worksheet requires students to identify which stage of mitosis different cell diagrams are in along with key processes associated with mitosis (e.g. chromosomes condense and become visible, nuclear membrane breaks down, etc). The worksheet is useful as either a plenary or starter activity to recap learning following a lesson on this topic Key words: mitosis, chromosomes, prophase, metaphase, anaphase, telophase, interphase, centromere, chromatid

An activity aimed at advanced biology students, this activity provides a series of bullet points related to the nature and mechanisms of hormones, local chemical mediators and the nervous system. Students are required to study the information and then draw their own diagrammatic representations of the information provided in this worksheet. Student diagrams can then be shared with the class, with students providing a commentary as to what each diagram is representing. A good way for students to gain a quick understanding and overview of the ways in which the human body communicates with itself.

A worksheet aimed at advanced biology students, this resource is useful as a recap and test of understanding on the topic of mitosis. Students are required to identify cells at different stages of mitosis, recall events that are occurring in cells at each stage and identify mitosis stages in a real micrograph as well as textbook-style diagrams. Keywords: mitosis, chromosomes, condense. prophase, metaphase, anaphase, telophase, interphase

A resource aimed at advanced level biology students who have just studied a topic on mitosis, this worksheet consolidates understanding by asking students to consider how the quantity of DNA in cells changes at different points during the cell cycle. The resource checks that students understand the difference between somatic cells and gametes, and whether they can visualise the appearance of chromosomes and hence the quantity of DNA present at different stages of cell division.
