An Egg
A floater that can sometimes be seen in the eye when looking into a blue sky. These were left over blood vessels that were helping to form your eyes before you were born.
No, the human egg cell is not visible to the naked eye as it is microscopic in size.
The cell structure visible in an Elodea leaf cell wet mount when examined with a compound light microscope is the chloroplast. These are the green organelles responsible for photosynthesis in plant cells, giving them their characteristic color.
Some organelles that are visible in the cell include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and vacuoles. These organelles can be observed under a light microscope due to their size and distinct structures.
First of all, by size. Prokaryots are bacteria and they are generally a lot smaller than eukaryotes. With most light microscopes, you can see a human cell quite clearly, and you can clearly distinguish the nucleus and in the nucleus you can distinguish euchromatin and heterochromatin. A bacterium on the other hand just looks like a dot. Its too small to try and see any interior structures through an average light microscope.Apart from that, in a eukaryotic cell in mitosis, if the nucleus is no longer present, the chromosomes are still clearly visible in the cytoplasm.
In the early stages of mitosis or meiosis (cell division), the chromatin strands become more and more condensed. They cease to function as accessible genetic material (transcription stops) and become a compact transportable form. This compact form makes the individual chromosomes visible, and they form the classic four arm structure, a pair of sister chromatids attached to each other at the centromere. The shorter arms are called p arms (from the French petit, small) and the longer arms are called q arms (q follows p in the Latin alphabet). This is the only natural context in which individual chromosomes are visible with an optical microscope.
Chromosomes are clearly visible only when a cell is undergoing cell division, specifically during the metaphase stage of mitosis or meiosis. During this stage, chromosomes condense and become visible under a microscope.
No, the human egg cell is not visible to the naked eye as it is microscopic in size.
The wavelength of visible light is longer than a human skin cell. Visible light has wavelengths ranging from about 400 to 700 nanometers, while a human skin cell is typically around 30 micrometers in size.
During cell division, structures like the chromosomes, spindle fibers, and centrioles are more clearly visible. Chromosomes condense and can be seen as distinct entities, spindle fibers form a dynamic network between the centrioles, and the centrioles organize the spindle apparatus.
No, because human cells don't have cell walls, only cell membranes.
40 nanometers, an individual cell cannot be seen. Only when stacked are they visible
Chromosomes are the rod-shaped, filamentous bodies present in the nucleus, which become visible during cell division. They are the carriers of the gene or unit of heredity. Chromosome are not visible in active nucleus due to their high water content, but are clearly seen during cell division.

The largest type of cell in the human body is the female egg cell, also known as an ovum. The ovum is large enough to be visible to the human eye and is roughly the size of a grain of sand.
Nerve cells can grow axons up to six feet in length. They are how ever the biggest. The Human egg cell is the biggest. The human ovum is typically around 120um and yes, it is visible to the human eye. The Anterior Horn Cell of the spine however, is around 135um thus making it the largest in circumference.
