Why plants need transport tissues

Large plants cannot rely on diffusion alone because roots, stems and leaves are far apart. They need vascular tissues arranged in vascular bundles to move substances efficiently.
Step-by-step lessons on Edexcel A A Level Biology Plant transport tissues, sustainability and conservation. Each one builds up to exam-style questions. Build a strong foundation in cell biology and biochemistry early on, since later topics on genetics, ecology and physiology all draw on these core concepts.
