This document outlines the requirements for a Moss Project assignment. Students will create an informational booklet about the phylum Bryophyta (mosses). The booklet should include: 1) Point form notes on the characteristics of Bryophyta on page one. 2) A hand drawn life cycle of a moss on page two, labeling structures and processes. 3) Biological drawings from prepared microscope slides of moss structures on page three. 4) A drawing from a collected moss sample under a microscope on page four, with labels of moss structures. 5) Answers to lab application questions on page five.

1. Moss Project

2. Moss Project
● You will work individually to create an
informational booklet about phylum bryophyta
● Booklet should be neat, well organized and
include supplemental drawings/pictures
Due Friday June 6

3. Page One - Information
● Use text and online resources to make point form
notes under each of the following headings:
● Phylum Bryophyta
– Examples
– Non-vascular land plants
– Habitat
– Ecological Importance
– Adaptations to life on land
– Alternation of Generations

4. Page Two – Moss Life Cycle
● Hand draw the life cycle of a typical moss
● Draw and label all relevant structures and processes
● Include:
● Mitosis
● Meiosis
● Fertilization
● Spores
● Gametes
● Protonema
● Germination
● Gametophyte
● Sporophyte
● Haploid
● Diploid
● Archegonium
● Antheridium

5. Page Three – Moss Structures
● Observe three prepared slides:
– Protonema developing from spore
– Male gametophyte: Antheridium
– Female gametophyte: Archegonium
● Complete three simple biological drawings
(labels & observations, no calculations)
● Include in your observations the functions of
each structure and where/when it is found

6. Page Four – Live Sample
● Take a walk around school grounds to find some moss
or bring a sample from home
● Collect a SMALL sample including the sporophyte
– 3-4 Individual plants with sporangium & rhizoids attached
● Examine your sample under the dissecting microscope
and make 1-2 biological drawings
● You may dissect open the capsule to examine the
structures and spores
● Attach one whole plant with clear tape to your page
● BONUS – Identify the species of moss you found (inc.
references)

7. Page Four – Drawing Labels
● False leaves
● Rhizoids
● Stalk/Seta
● Sporophyte
● Gametophyte
● Capsule
● Calyptera
● Peristome
● Operculum

8. Page Five - Questions
● Answer lab application questions #1-6 from
page 260 in the Nelson Text (Whale)
