Klebsormidium

Klebsormidium is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Klebsormidium rather than just read about it. In short: Klebsormidium is a genus of filamentous charophyte green algae comprising 20 species. The name was proposed in 1972 to resolve confusion in application and status of Hormidium and was given for the German botanist Georg Albrecht Klebs.

Key takeaways

Klebsormidium belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Klebsormidium to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Klebsormidium from memory before moving on to harder problems.

Reference excerpt

Klebsormidium is a genus of filamentous charophyte green algae comprising 20 species. The name was proposed in 1972 to resolve confusion in application and status of Hormidium and was given for the German botanist Georg Albrecht Klebs. The algae occurs mostly in soil and on moist substrates, nevertheless, aquatic and one marine species are also known. Many Klebsormidium-species are able to synthesize substances for UV protection, the so-called mycosporine-like amino acids. The draft genome sequence of Klebsormidium nitens NIES-2285 (called K. flaccidum at the time of publication) was published in 2014.

Description Klebsormidium forms uniseriate (one cell thick), unbranched filaments. Cells are cylindrical or barrel-shaped. The cell wall may be thin or thickened, and is sometimes made of H-shaped pieces. Each cell contains a single parietal chloroplast which encircles around 40 to 70% of the cell wall, usually with a single pyrenoid. Klebsormidium reproduces asexually but not sexually. It produces zoospores with two flagella, which are released from cells through a pore. It can also produce aplanospores and akinetes. The genus can be difficult to distinguish from Ulothrix, but Ulothrix tends to have chloroplasts that are wider and encircling nearly all of the cell.

Species The valid species currently considered to belong to this genus are:

The species of Klebsormidium are in critical need of a taxonomic revision. Traditional morphological characteristics used to delimit the taxa, such as the width of filaments or shape of cells, are unreliable and do not map well to phylogenetic groups.

Worked examples

Example 1 — a first encounter with Klebsormidium

Start with the simplest possible case. Write down what Klebsormidium claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Klebsormidium before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Klebsormidium ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Klebsormidium

In research: Klebsormidium appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Klebsormidium in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Klebsormidium is common in secondary-school and first-year university syllabi. It links to neighbouring topics Charophyta, Charophyta genera, Green algae stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Klebsormidium outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Klebsormidium in simple terms?

Why does Klebsormidium matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Klebsormidium?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
