Description: Preparing a microscope slide of an onion root tip to observe mitosis is a fascinating experiment that allows students to witness the intricate process of cell division firsthand. 

This work consists of instructions for building a DIY arm model, during which students will study the mechanism of the biceps and triceps.

Laboratory work explores the important biological role of the gaseous phytohormone ethylene in the process of fruit ripening. During the experiment, students study how ethylene affects the fruit ripening of various plants. They conduct observations, measure the rate of fruit ripening under different temperature conditions and compare it with control samples.

In this practical work, students will explore the world of plant taxonomy, learn to identify plant species, by defining their characteristic features.

Description of the work This practical work is aimed at studying the process of plant transpiration and determining the factors that affect its intensity. During the experiment, students analyze the influence of various internal parameters of plants on the rate of water evaporation through their leaf lobes.

Information about work In this work, students consider the mechanism of the transpiration process in plants. They will study the effect of external factors on transpiration and will learn to do by themselves a potometer (transpirometer) – a device for measuring the speed of transpiration.

Information about the work In this work, students will study the effect of bile on the breakdown of fats during digestion.

Information about work In this work, students explore factors include temperature and pH that affect enzyme activity of catalase.
