Self-study module Introduction to Plant Biology - Plant anatomy

This self-study module is part of the series ‘Introduction to Plant Biology’ and focusses on plant anatomy. It is designed for students studying basic plant biology and for teachers seeking clear explanations and illustrative figures for educational use. The module covers the plant life cycle and provides a basic understanding of plant structure and function, from plant cells to whole organs. Students explore the anatomy of plant organs (stem, root, leaf, flower, and seed) and specialized cell types such as stomata and root hairs. In addition, the module introduces key plant cell organelles, including the nucleus, chloroplasts, mitochondria, vacuole and the cell wall, and explains their roles in plant function.

Self-study module Introduction to Plant Biology - Plant hormones

This self-study module is part of the series ‘Introduction to Plant Biology’ and introduces plant hormones, explaining how chemical signaling enables communication and coordination within plants. It is designed for students learning basic plant biology and for teachers seeking clear figures and explanations for educational use. The module covers fundamental concepts of cell signaling and signal transduction and examines the functions and interactions of major plant hormones, including auxin, cytokinin, abscisic acid, gibberellins, ethylene, salicylic acid, jasmonic acid, brassinosteroids, and strigolactones, in regulating plant growth, development, and responses to the environment.

Self-study module Introduction to Plant Biology - Plant nutrients

This self-study module is part of the series ‘Introduction to Plant Biology’ and introduces plant nutrients and their essential roles in plant growth and development. It is designed for students studying basic plant biology and for teachers seeking clear explanations and illustrative figures for educational use. The module explores the distinction between macronutrients and micronutrients, provides examples of key nutrients, and explains how plants respond to different types of nutrient deficiencies. In addition, it addresses how nutrient management practices in agriculture are used to prevent deficiencies and reduce yield losses.

Self-study module Introduction to Plant Biology - Abiotic stress

This self-study module is part of the series ‘Introduction to Plant Biology’ and introduces abiotic stress in plants and explains how plants cope with and adapt to challenging environmental conditions. It is designed for students learning basic plant biology and for teachers seeking clear figures and explanations for educational use. The module covers key abiotic stresses - heat, cold, flooding, drought, salinity, and high light intensity - and examines the physiological, structural, and adaptive strategies plants use to survive and grow under these conditions.

Self-study module Introduction to Plant Biology - Water in plants

This self-study module is part of the series ‘Introduction to Plant Biology’ and focuses on the role of water in plants, explaining how water is taken up, transported, and regulated to support plant growth and survival. It is designed for students learning basic plant biology and for teachers seeking clear figures and explanations for educational use. The module covers water uptake by roots, long-distance water transport through the xylem and phloem, the relationship between stomata and transpiration, and examines how environmental factors influence these processes.

Self-study module Introduction to Plant Biology - Photosynthesis light-dependent reaction

This self-study module is part of the series ‘Introduction to Plant Biology’ and introduces the light-dependent reactions of photosynthesis and their role in converting light energy into chemical energy. It is designed for students studying basic plant biology and for teachers seeking clear explanations and illustrative figures for educational use. The module explains the two photosynthetic reactions: light-dependent and light-independent, with a focus on the processes occurring in the chloroplast during the light-dependent phase. Students explore the formation of the energy carriers ATP and NADPH, the splitting of water into oxygen, and the role of fluorescence as an indicator of disturbances in the photosynthetic process and therefore plant health.

Self-study module Introduction to Plant Biology - Photosynthesis light-independent reaction

This self-study module is part of the series ‘Introduction to Plant Biology’ and focuses on the light-independent reactions of photosynthesis, the Calvin cycle. It is designed for students studying basic plant biology and for teachers seeking clear explanations and illustrative figures for educational use. The module explains how plants convert carbon dioxide into sugars, the role of rubisco in carbon fixation, and the process of photorespiration. Students explore how photosynthesis is linked to stomatal function, how plants have adapted to extreme environmental conditions through C₄ and CAM photosynthesis, and how sugars are converted into starch for energy storage and the role of source-sink relationships. Finally, the module connects photosynthesis to plant respiration and overall energy balance.

In a Nutshell | Sniffing the Soil with Rosa Boone

In the fourth episode of In a Nutshell, host Antonia Leise invites the Ph.D. candidate in Plant Ecology and Physiology Rosa Boone into the studio. In this episode, we go below ground and have a close look at the soil our food depends upon – or, more precisely, how an electronic nose can help sniff out whether grassland soil is healthy or not. Why is healthy soil important? How can smell help in determining soil health? And what do Pickwick tea bags have to do with all of this? Rosa Boone knows the answers – even though determining what healthy soil is might not be as straightforward of a question as one might think. Rosa Boone is a PhD candidate at the Faculty of Science and currently developing an electronic nose to help farmers determine whether their soil is healthy or not. She has long been fascinated with nature restoration and works closely with farmers and artists to make the topic of soil health more accessible. Want to know more about soil health? Follow Rosa’s tip and watch the documentary Planet Soil (2023; Dutch: Onder het Maaiveld) or read the book Nose Dive (2022) by Harold McGee.
