OBSERVING MOSSES AND FERNS


By S.Bastian
Mosses and ferns are simple non-flowering plants. We have observed them in the class and compared their characteristics.

 Ferns have very divided leaves called fronds. On the back of the fronds we have seen sorus, capsules that contain spores. Ferns are vascular plants. They have horizontal stems called rhizomes.

 Mosses have tiny leaves called phylodes. They absorb water through them. Their roots are only used to attach themselves to a surface, but they are called non true roots because they are unable to absorb water. Mosses grow filaments with capsules at the end that contain the spores for reproduction.
 María Cátedra from E1A has brought a fantastic sample of moss, where we have been able to see the filaments and capsules very clearly. We have also taken close up photographs of these to share on Science Magazine!

We have done scientific diagrams of both and labelled the parts.
