Energy and nutrients Maintain cover with living plants and mulch, with as much diversity as possible. Shelter Keeping the soil covered as much as possible. Reduced disturbance Minimizing tillage, driving, and chemical interference. Earthworm activity* All of the above.
How do protozoa help the soil?
They tend to be very active, and sometimes will notice the movement of soil particles before you see the organism itself. When protozoa graze on bacteria, they free up nutrients that have been immobilized in bacterial cells, and make them available to plants again. This makes them incredibly important members of the soil ecosystem. They have also been found to promote plant health and improve growth independently of nutrients. Protozoa are known to be picky eaters. Each species hunts for specific types of bacteria. That means diversity in protozoa may be useful as an indicator of bacterial diversity in the soil. The more unique types of protozoa you can find in your soil, the better! There are three main categories of protozoa, based on their physical characteristics and movement: Amoebas 10-50 μm Flagellates 3-10 μm Ciliates 10-80 μm Amoebas are protozoa without a fixed shape. They move with a slow oozing motion, extending temporary “false feet” or pseudopods to slide across surfaces or engulf their food. Flagellates have one or two long, whip-like appendages that they use to move. They often have a twitching, spinning, or rocking motion. Ciliates come in many diverse shapes and sizes. They have many smaller hairs (called cilia), which allow them to move much faster and often more smoothly than flagellates.
Why are fungi good indicators of ecological succession?
Because fungi grow slowly and are easily disturbed, they can be good indicators of ecological succession. Agricultural soil often has low fungal populations and forest soil tends to be very rich in fungal networks. Below are some examples of fungal hyphae that you can compare with your soil sample.

Bacteria are very small; often just 1 μm in diameter (0.001 mm). The image below demonstrates how tiny they are at 400x magnification in a microscope with a field of view 500 μm (0.5 mm) across. Bacteria are grouped into three broad categories based on the shape of the cells.
What microscope is used to view a tissue?
A microscope is almost always necessary for all kinds of physiological recordings. For extracellular recordings, a low-power dissecting microscope is usually adequate to see laminae or gross morphological features of the tissue and brain. For intracellular physiology or patch clamp techniques, a microscope with high enough magnification power to see individual cells (300–400×) is necessary. These microscopes are usually equipped with optical contrast enhancement to view cells in unstained preparations. An inverted microscope is usually preferable for two reasons: (1) it allows easier electrode access to the sample, as the objective lens is below the chamber; and (2) it provides a larger, more solid platform upon which to bolt the micromanipulator.
What type of microscope is used for confocal imaging?
The microscope used for confocal imaging can be an upright or an inverted model. It can use the 160-mm fixed-tube-length optics or the newer infinity optics. Most confocal attachments are configured to work with either type of microscope. An upright model is useful for fixed specimens, and living specimens when used with a water immersion objective. An inverted model is better for living samples that need to be kept sterile, or if access to the samples is required when using micromanipulators and microinjectors.
What is a photolithography microscope?
Microscope projection photolithography (MPP) based on a protein-friendly photoresist is a versatile tool for the fabrication of protein- and cell-micropatterned surfaces. Photomasks containing various features can be economically produced by printing features on transparency films. Features in photomasks are projected by the objective lens of a microscope, resulting in a significant reduction of the feature size to as small as ~ 1 μm, close to the practical limit of light-based microfabrication. A fluorescence microscope used in most biology labs can be used for the fabrication process with some modifications. Using such a microscope, multistep MPP can be readily performed with precise registration of each micropattern on transparency film masks. Here, we describe methods of the synthesis and characterization of a protein-friendly photoresist poly (2,2-dimethoxy nitrobenzyl methacrylate-r-methyl methacrylate-r-poly (ethylene glycol) methacrylate) and the setups of fluorescence microscopes and the MPP procedures. In addition, we describe the protocols used in the micropatterning of multiple lymphocytes and the dynamic micropatterning of adherent cells.
What is the image of the microscopic object on the retina called?
With a microscope with 100 × magnification, the image of the microscopic object on the retina will be as large as if the object were 100 times larger than its actual size and placed at the distance of distinct vision. The magnified apparent image that occurs at the distance of distinct vision is known as the virtual image.
Why do we use inverted microscopes?
Inverted microscopes are so called because the objective lens points upward at the sample and focusing is accomplished by moving the objective lens and not the stage. Because the stage is generally heavier than the objective turret, inverted microscopes are less prone to focal drift due to gravity. Fluorescence studies are well suited to inverted microscopes because the imaging light path is below the specimen, within the microscope body where it has a low center of gravity and is less susceptible to vibration-induced aberrations. For this reason, biophysics labs generally prefer inverted microscopes. Correspondingly, transmitted light imaging modes (e.g., DIC) are normally less stable on inverted microscopes as the illuminating light path is elevated, poorly supported, and prone to vibration. One benefit of inverted microscopes is the ease of access to the specimen such as for microinjection at a step angle (as preferred for injecting C. elegans; this is not easily accomplished on an upright microscope).
What is an inverted microscope stand?
Inverted microscope stands are preferable for most live-cell imaging applications . With the inverted microscope design, the specimen is imaged with an objective lens from beneath the microscope stage. This allows for sufficient room on the microscope stage for cell culture dishes filled with media and heated incubation chambers, and allows easy access to the specimen for perfusion or microinjection. High-quality inverted microscope stands are heavy and stable, making them resistant to focus drift. To prevent vibration that can degrade resolution, the microscope stand should be mounted on a vibration isolation table.
What is a horizontal microscope?
