@jirgytech: WHY DO PLANTS DIE IN WATERLOGGED SOIL? 🌱 Root Rot & Chlorosis Explained O Level Biology Why do plant roots rot in waterlogged soil, and why do the leaves turn yellow? 🌱 In this O Level Biology lesson, we explain how waterlogging reduces oxygen in the soil, affects root respiration and mineral uptake, and eventually causes root rot, chlorosis and poor plant growth. A very important concept for O Level Biology, plant nutrition, respiration and ecology questions. Watch to the end and test yourself: Why can some plants such as cocoyams survive waterlogged conditions while beans may die? #STEMTok #learnontiktok #biology #OLevelBiology #plantbiology
