Fast plants for finer science - an article from the Journal of Biological Education

An article introducing 'fast plants' (rapid-cycling brassicas) for use in the classroom.

Student Sheet 1 - Planting instructions for rapid-cycling brassicas

'Fast plants', or rapid-cycling brassicas, are a fascinating way to look at all sorts of biology topics, including plant growth, tropisms, floral reproduction, pollination, embryonic development, and genetics. This student worksheet introduces how to plant the rapid-cycling brassicas.

Student Sheet 4 - Pollen Tube Growth

The growth of pollen tubes makes a fascinating practical in the lab, and is easily observed under medium power of a microscope over the course of a double lesson. This resource includes full teaching and technical notes, together with guidance on which pollen grains to use at what time of year, a zip file of sample images and a student's worksheet.

Student Sheet 5 - Investigating Seed Germination

A simple experiment to investigate the germination of seed under different conditions, by growing seeds upright in Petri dishes. It allows students to make quantitative measurements of root / shoot growth, length of root hairs, etc, as well as % germination. This technique can also be used for investigations into the effect of acid rain.

Pollen and other Airborne Particles

Construct your own school pollen trap to isolate and identify the pollen and other airborne particles that contribute to respiratory illness

Protoplast Isolation

Protoplasts (cells which have had their cell wall removed) can be isolated from a range of plant tissues. This resource introduces protoplasts and gives a technique for isolating them.
