Desmids

Desmids are an order (Desmidiales) of green algae,[1] comprising around 40 genera and 5,000[2] to 6,000[3] species, found mostly but not exclusively in fresh water

Volvox

Volvox are spherical colonies of green cells situated in a hollow ball of mucilage. Each cell has a tail, or flagella, and these tails will all move in unison to propel the entire colony through water. These colonies will often show daughter cells in various stages of development. Sometimes colonies will be found to have […]

Amoeba

Amoebae’s most recognizable features include one or more nuclei and a simple contractile vacuole to maintain osmotic equilibrium. Food enveloped by the amoeba is stored and digested in vacuoles.

Moss Capsule

Mosses are small, soft plants that are typically 1–10 cm (0.4–4 in) tall, though some species are much larger. They commonly grow close together in clumps or mats in damp or shady locations.

Spirogyra

Spirogyra is a filamentous algae found in nutrient-rich, warm waters, such as ditches and dune pools. It begins life underwater, but often rises to the surface as green patches buoyed by the bubbles of oxygen it produces.

Moss Sporophyte

Sporophyte moss is when the plant cells are diploid, meaning there is a double portion of chromosomes in their cells. Sporophyte moss produces spores by meiosis, and then these spores develop into gametophytes. In general, mosses are non-vascular plants and are distinguished by their multi-cellular rhizoids. These rhizoids are root-like structures that anchor the plant […]

Gametophyte Moss2

Gametophyte moss is when the plant cells are haploid, meaning there is a single portion of chromosomes in their cells. Gametophyte moss produces male or female gametes by the process of mitosis. When a female and male gamete fuse together, a zygote is produced which develops into a sporophyte. In general, mosses are non-vascular plants […]

Moss Antheridial Head

In ferns the antherdia is part of the reproductive system. The gametophytes or thallus, produce both motile sperm in the antheridia and egg cells in separate archegonia.

Algae

Algae are a large and diverse group of simple, typically autotrophic organisms, ranging from unicellular to multicellular forms, such as the giant kelps that grow to 65 meters in length. The largest and most complex marine forms are called seaweeds. They are photosynthetic like plants, and “simple” because their tissues are not organized into the […]

Diatoms

Diatoms are a major group of algae, and are one of the most common types of phytoplankton. Most diatoms are unicellular, although they can exist as colonies in the shape of filaments or ribbons (e.g. Fragillaria), fans (e.g. Meridion), zigzags (e.g. Tabellaria), or stellate colonies (e.g. Asterionella).

Microbial Mat 3

Microbial Mats are of interest to scientists because they are representatives of the oldest life on Earth. These thick layers of microbes would grow almost anywhere on Earth, but the evolution of plants started a competition for resources and as animals appeared they consumed the mats as food. With the proliferation of plants and animals […]

Moss Antheridial Head2

An Antheridial head is the male sex component of gametophyte mosses. Mosses produce these small sex structures at regular intervals depending on the species and weather conditions. Water is needed to transport sperm from the antheridial head to the female counterpart called the archegonium. Once there, fertilization takes place and a zygote is produced making […]

Flower

In addition to facilitating the reproduction of flowering plants, flowers have long been admired and used by humans to beautify their environment but also as objects of romance, ritual, religion, medicine and as a source of food.

Moss Leaf

Liverworts and mosses are very similar, and the ways to tell the two apart are to look at their slightly different leaves. Moss leaves are of equal size, spirally arranged, and are not lobed. They are usually in more than three rows around the stem. Liverworts and mosses are very similar, and the ways to […]
