Thursday: Warm, damp and airy

Rocket checks the turned bag. "The roots bent down!"

Raven asks, "What do you notice on the roots?"

Nova says, "Look for tiny hairs."

Root hairs

Look closely at a new root.

You may see tiny fuzzy hairs.

They are called root hairs.

Most of the water a plant drinks goes in there.

Not too cold, not too wet

Most seeds need warmth to sprout.

A bean in cold soil may rot.

Seeds need air too.

Too much water leaves too little air.

So damp is good, but soaking wet is not.
