A resource aimed at advanced biology students, this worksheet is ideal as a starter or plenary recap of the light independent reactions of photosynthesis. The worksheet includes a space for students to draw out the series of light independent reactions from memory, but importantly, they are then asked a series of questions to identify the role of each substance. This is a very useful way of ensuring that students have understood the details of the reaction rather than just repeating diagrams parrot-fashion. Key words: photosynthesis, light independent, photosystems, chlorophyll, chloroplasts, thylakoid, stroma, electrons, reduction, oxidation, phosphorylation, ATP, NADP, RUBP, G3P, TP, RUBISCO, Calvin cycle

A worksheet that recaps the basics of monohybrid cross diagrams using a (hypothetical) pink sheepdog as an example! The worksheet provides a template for students to organise and lay out their work clearly and finsihes with a challenge question requiring students to explain why predicted ratios do not necessarily match actual ratios. Key words: monohybrid, test, back, cross, predicted, inheritance, dominant, recessive

A resource aimed at advanced biology students, this worksheet links topics on osmosis and transpiration. The worksheet begins with a recap of basic knowledge related to osmosis, predicting water movement between cells through use of their water potential values. The worksheet then moves on to consider water potential gradients that exist through an entire plant followed by the structure (as seen in longitudinal and transverse section) of roots. Key words: osmosis, water potential, apoplast, symplast, cell wall, casparian strip, active transport, minerals, epidermis, endodermis, root hair cells, cortex, xylem, transpiration

A resource aimed at advanced biology students, this worksheet focuses on how food is digested in both the mouth and stomach.
