Examples of flame cell in the following topics:
-
- Flame cells and nephridia remove the waste from bodies through filtration in a manner similar to a kidney.
- Excretory cells known as flame cells developed in flatworms, while nephridia developed as excretory cells in annelids.
- The cells in the tubules are called flame cells (or protonephridia) because they have a cluster of cilia that looks like a flickering flame when viewed under the microscope .
- Flame cells function like a kidney, removing waste materials through filtration.
- In the excretory system of the (a) planaria, cilia of flame cells propel waste through a tubule formed by a tube cell.
-
- The epidermal tissue is a single layer cells or a layer of fused cells (syncytium) that covers a layer of circular muscle above a layer of longitudinal muscle.
- The mesodermal tissues include mesenchymal cells that contain collagen and support secretory cells that secrete mucus and other materials at the surface.
- Flatworms have an excretory system with a network of tubules throughout the body with openings to the environment and nearby flame cells, whose cilia beat to direct waste fluids concentrated in the tubules out of the body.
- There is neither a circulatory nor respiratory system, with gas and nutrient exchange dependent on diffusion and cell-cell junctions.
- Each may contain an excretory system with flame cells and both female and male reproductive structures.
-
- Aseptic technique or sterile technique is used to avoid contamination of sterile media and equipment during cell culture.
- Sterile technique should always be employed when working with live cell cultures and reagents/media that will be used for such cultures.
- This technique involves using flame to kill contaminating organisms, and a general mode of operation that minimizes exposure of sterile media and equipment to contaminants.
- This requires that exposure of containers of sterilized culture media to outside air should be minimized, and that flame is used to "re-sterilize" container lids and rims.
- This means passing rims and lids through the flame produced by a Bunsen burner in order to kill microorganisms coming in contact with those surfaces.
-
- Other heat sterilization methods include flaming and incineration.
- Flaming is commonly used to sterilize small equipment used to manipulate bacteria aseptically.
- Another problem is that gas flames may leave residues on the object, e.g. carbon, if the object is not heated enough.
- A variation on flaming is to dip the object in 70% ethanol (or a higher concentration) and merely touch the object briefly to the Bunsen burner flame, but not hold it in the gas flame.
- It has the advantage that it leaves less residue than a gas flame.
-
- Fuel cells are electrochemical devices capable of transforming chemical energy into electrical energy.
- Fuel cells require less energy input than other alternatives and perform water electrolysis at lower temperatures, both of which have the potential of reducing the overall cost of hydrogen production.
- This means that any leak of hydrogen from a hydrogen:air mixture will most likely lead to an explosion if it comes into contact with a spark or flame.
- Pure hydrogen-oxygen flames burn in the UV range and are invisible, so a flame detector is needed to detect if a hydrogen leak is burning.
-
- Sulfur burns with blue flame, is insoluble in water, and forms polyatomic allotropes.
- Sulfur burns with a blue flame, concomitant with formation of sulfur dioxide, notable for its peculiar suffocating odor.
- Sulfur burns with blue flames and forms blood-red liquid when it melts.
-
- The candle's flame burns until extinguished by oxygen deprivation, which creates a carbon dioxide-rich, oxygen-poor atmosphere in the jar.
- Some human pathogens are grown directly on cells cultured from humans.
- The human cell culture known as McCoy cell culture is used to culture this bacteria .
- Light microscope view of cells infected with chlamydiae as shown by the brown inclusion bodies.
-
- So-called flame vessels, along with the closely related crown-formed vessels , are among the most distinctive forms from this period; representative forms such as clay figurines of people and animals also appeared around this time.
- "Crown-formed vessel," a variation on the flame vessel style for which Jōmon art is famous.
-
- Three basic categories of cells make up the mammalian body: germ cells, somatic cells, and stem cells.
- Pluripotent stem cells undergo further specialization into multipotent progenitor cells that then give rise to functional cells.
- Hematopoietic stem cells (adult stem cells) from the bone marrow that give rise to red blood cells, white blood cells, and platelets
- Mesenchymal stem cells (adult stem cells) from the bone marrow that give rise to stromal cells, fat cells, and types of bone cells;
- Epithelial stem cells (progenitor cells) that give rise to the various types of skin cells
-
- In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues.
- Stem cells can now be artificially grown and differentiated into specialized cell types with characteristics consistent with muscle or nerve cells through cell culture.
- In one, the daughter cells are initially equivalent but a difference is induced by signaling between the cells, from surrounding cells, or from the precursor cell.
- Stem cells are indicated by (A), progenitor cells by (B), and differentiated cells by (C).
- Pluripotent, embryonic stem cells originate as inner cell mass (ICM) cells within a blastocyst.
