Suggest how the gas gets out of the leaf. When the leaf is put in warm water.
Answers
Answer:
Push the leaf into some warm water. ... Leaves have tiny holes in their lower surfaces, called stomata, which allow carbon dioxide to get into the leaf from the air.
Answer:
Plants use their leaves to recycle CO2 and switch it into food for themselves and oxygen for us. During this experiment, produce an atmosphere wherever you'll see this carbon dioxide/oxygen exchange happening!
Directions-
- Ask your kid to rigorously observe the leaf. What do they see? however will the leaf feel? will they hear it breathing?
- Fill the bowl with temperature water.
- Ask your someone to put the leaf within the bowl of water.

How it works
Ask your youngsters what happens after they hold their breath, go underwater, and let their breath out. Seemingly they'll say that they'd see bubbles rising to the highest of the water. That's kind of like what you're seeing here!
When the leaf is submerged it's exploitation light-weight to continue the method of chemical change. A part of this method is to let oxygen out of the leaves. It's this oxygen that you just square measure seeing as bubbles within the water. Thus whereas a plant doesn't breathe like we tend to do (using lungs) it will soak up and unharness air. you're “seeing” the invisible method of photosynthesis.
