This is an animated PowerPoint presentation that covers section 3.2 Transport in plants of the Edexcel IGCSE Biology course.
The PowerPoint covers the following questions:
Do you understand that movement of water into and out of cells happens by osmosis? Can you write a definition for osmosis? How is water absorbed by root hair cells? Why do multicellular organisms need a transport system? How would you carry out experiments to demonstrate osmosis using living and non-living systems? What is the role of xylem? What is transpiration? How do changes in humidity, wind speed, temperature and light intensity affect the rate of transpiration? What experiment would you perform to investigate the role of environmental factors in determining the rate of transpiration from a leafy shoot? Can you describe the role of phloem? Why is it important in plants to have turgid cells?
The PowerPoint is designed to directly address each relevant point in the syllabus. It is simple and straight to the point covering the topic in just the right amount of detail.
It's a fantastic resource for both teachers and students or a great tool for revision.
Many of the slides have animations in that will only work when viewed in slideshow mode, so please use that when working through the presentation.
