Investigating Moss

Yesterday my granddaughter and I found some moss growing in the yard. She was quite intrigued by it, so I pulled up a bit, and brought it in the house for further study. She looked at in under different powers of magnification. She liked how soft it was, and how it looked like a mini forest. She also observed how the roots (called rhizoids) are not long, and do not go deep into the ground. Moss grow in mounds, or mats. I also had her take note of where it was growing: a damp, shady place. Mosses don't produce flowers, but during growing season, it will send up tiny stalks with a capsule on top that contain spores which will be released, and spread by the wind, or water to create new patches of moss.

Rhizoids are moss roots. They are as thin as a strand of hair.

We found 2 different kinds of moss in the yard.

Moss between paving stones.

Some moss grows in mounds, while others are more mat-like.
This moss has sent up the slender stalks with the capsules, called sporangia, on top which contain the spores.
