5 Major Types of Plant Hormones that Regulate Plant Behavior and Development

So in the last video, we have talked about phototropism, which is a plant’s tendency to grow toward the light. There’s actually Auxin, a kind of plant hormones, that makes phototropism happen by elongating plant cells. So say if a plant senses the light coming from one direction, Auxin will accumulate in the dark side […]

What Is Eutrophication | Agriculture | Biology | FuseSchool

Eutrophication is the process that can happen in a water body, like a river or a lake, when too many nutrients are added to the system. Eutrophication starts with fertilizers, which are rich in nutrients like nitrate and phosphate, are washed into the river or lake system. This leads to an increase in nutrient concentrations […]
