These two are just single-celled organisms; basically a bunch of building blocks and cell machinery wrapped in a membrane, and here you can see what happens when that membrane bursts and spills its contents out. . The smaller organism, Holophrya, has harpoon-like structures around its cell mouth that are expelled to immobilize prey. They usually go after smaller microorganisms or decomposing organic matter, so this whole scene was so unexpected my jaw was on the floor. . When I found these two, Holophrya’s little harpoons had already fired and pierced the cell membrane of the larger organism, a Stentor, and it was tugging on the Stentor’s membrane. After a few seconds, the membrane popped almost like a balloon, and the Stentor’s cell contents spilled into the environment for Holophrya to feed on. . Holophrya has sensory mechanisms that let it detect the chemical signals coming from the spilled contents of the Stentor. So it kept swimming around for minutes, swallowing all the soup-like cytoplasm droplets and solid chunks of organelles, and even the bits of lunch Stentor had earlier. . While Holophrya was feeding on its spilled “guts,” the Stentor was busy repairing the hole in its membrane. Although it lost a lot of cell mass, Stentor has the ability to recover from all this and regenerate its deformed cell back to normal like nothing has happened. I wish I had that skill of regenerating emotionally, I’m like a savant of sad memories and broken cell membranes. 😂 . Thank you for reading! I’ll share a three-minute clip of this on my exclusive pages so you can watch the Holophrya keep feeding on the bits while the Stentor continues to repair itself. Your support makes it possible for me to keep posting, and I appreciate it. . Best, James Weiss

(english version below) Wurmfarn (Dryopteris filix-mas) : Auswerfen der Sporen aus den Sporenkapseln unter dem Mikroskop. Hierbei wurden von einem trockenen Wedel Sporenkapseln abgekratzt und in wasserfreiem Glycerin eingebettet. Anschließend wurde Wasser unter dem Deckglas hindurchgezogen, dadurch reisst die Sporenkapsel und schleudert die Sporen aus. Unter den kontrollierten Bedingungen kann man die einzelnen Phasen dieses Prozesses gut sehen. Zeitraffer 400%. Musik aus dem Album "What is the opposite of ambivalence" von @dvvvdvvv, Ausschnitt aus track “spending“, vielen Dank ! (english version below) Worm fern (Dryopteris filix-mas) : Ejection of the spores from the spore capsules under the microscope. Spore capsules were scraped from a dry frond and embedded in anhydrous glycerine. Water was then drawn under the cover glass, causing the spore capsule to rupture and eject the spores. The individual phases of this process can be clearly seen under the controlled conditions. Time lapse 400%.

🔬 Observing Chromosomes in Onion Cells Under a Microscope. Onion (Allium cepa) root tips are commonly used in biology labs to study mitosis, the process of cell division. This is because the root tip is a region of active growth, where cells are rapidly dividing, making it easier to observe chromosomes. What you see? - Interphase: The nucleus is visible, but chromosomes are not yet distinct. - Prophase: Chromosomes condense and become visible. - Metaphase: Chromosomes align at the cell’s equator. - Anaphase: Chromatids separate and move to opposite poles. - Telophase: New nuclei form at each pole. This method is a classic way to visualize the stages of mitosis and understand how genetic material is duplicated and distributed during cell division. 📹 by dr.bioforever (yt) #botanystudents☘️ #botanystudent #ecologystudent #cellbiology #medicalstudents

Have you ever seen a live cell under a microscope? 🦠 Meet paramecium. A single-celled protist. I was observing this little guy for a while when I realized it had slowed down its movements and flattened out quite a bit. Most of the water between the cover slip evaporated and the slide, squishing paramecium a bit. When it finally slowed down and stayed in one spot I was able to fully appreciate its complexity. See if you can spot a few organelles 😄

Some great fluorescence microscopy visualizing cells undergoing mitosis in real time.
