why do why do plants need water
Answers
Answer:
Plants need light, water, air, nutrients, and a comfortable temperature to survive and thrive. We all know that plants need water, but WHY do they need water? It turns out there are at least six key reasons that plants need water to grow:
Seeds depend on water to germinate.
Water is one of the primary signals telling a plant seed that it’s time to germinate and grow.
Plants are mostly made of water.
Their cells are 80-90% water! The water fills the cells and holds plants upright, giving them their shape/volume.
Water is a main ingredient in photosynthesis, the process by which plants create their energy.
Plants use water to regulate their temperature.
Plants release water from their stems and leaves to cool down (plants “sweat”).
Water delivers essential nutrients to plants.
Plants can only absorb the nutrients they need when the nutrients are in a liquid solution with water.
Plant “helpers” depend on water.
The beneficial soil organisms that help plants grow all depend on access to water for survival.
So there are multiple reasons that plants need water to live! Read on to learn more about each way plants use and depend on water to grow.
