How does moss reproduce asexually

Basic Moss Biology. Introduction This section was designed to give interested folks answers to common questions about mosses as well as clarify what a moss is and what it is not. For instance, one could read about "Spanish moss" growing profusely over vegetation in Flori da and the eventual death it brings its plant victims, consequently developing a negative opinion about moss in general. People and moss have been engaging in this struggle for years and the mosses deserve to have their story told.

Let's see if you change your mind as we more fully explore what a moss truly is. What are Mosses? When asked to visualize what a plant is, many of us picture a herbaceous plant such as a sunflower, or a woody plant such as a maple tree.

We think of "plants" as possessing roots, a stem or trunk , flowers, fruit, and seeds. Most of us do not automatically think of the plants that grow on rocks, rooftops, concrete, and any other moisture-laden area; however, this opportunistic bunch, choosing many eclectic substrates, exists. Their leaves are mostly one cell thick, they have no true roots, stems, flowers, or fruit, and instead of seeds they have spores.

For more information, read on, and consult Richardson Schofield , Shaw and Goffinet , and Sterling For in-depth information on the ecology of mosses, see Janice Glime's online book, Bryophyte Ecology.

How do mosses reproduce and spread? Mosses spread in multiple ways, but unlike flowering plants, they depend on moisture to sexually reproduce. Mosses reproduce by spores, which are analogous to the flowering plant's seed; however, moss spores are single celled and more primitive than the seed.

Spores are housed in the brown capsule that sits on the seta. As the spores ripen they are dispersed from the capsule, and some land in areas where there is enough moisture for them to grow. The young moss looks like a very thin tangled mass of branching green hairs. Buds will appear next on the green hairs, from which tiny stalks and slim leaves will grow.

Some mosses have cups on their tops that produce sperm, these are male plants. The female counterpart has eggs between her overlapping leaves. Water is a necessity for fertilization; as the sperm become mature they have to swim to the eggs to fertilize them. The fertilized egg then produces the stalked brown capsule.

Chemical attraction ensures the sperm cells find the egg within the female archegonia. The foot connects the spore stem to the main plant — providing access to food and water. The capsule is a small pod that contains the spores. Inside the capsule can be anywhere from 4 to over a million spores depending on the species of moss.

Germinating spores do not form new plants immediately. This is a thin, filament like, branching plant. Asexual also known as vegetative propagation is when part of the plant breaks off and grows into a new plant with the same genetics as the original plant. This can happen when the stem of a large clump of moss dies back, resulting in the clump becoming individual plants. Another method occurs when parts of the stem or even a single leaf from the moss plant are broken off — these bits can then regenerate to form a new plant.

This one has a light and a 60X magnification lens as well. We hope you enjoy the content on Moss Lovers. Moss propagation can take a long time. Please remind students to remain patient as they observe their moss grow. Extensions Make a moss terrarium.
