During meiosis, key features that can be observed under a microscope include the pairing of homologous chromosomes, crossing over between chromosomes, and the separation of chromosomes during cell division. These processes result in the formation of haploid cells with genetic variation.
The key characteristics and distinguishing features of the meiosis stages when observed under a microscope include the reduction in chromosome number, the occurrence of crossing over during prophase I, the alignment of homologous chromosomes during metaphase I, the separation of homologous chromosomes during anaphase I, and the separation of sister chromatids during anaphase II. These stages are essential for the production of genetically diverse gametes.
When examining an onion cell under a microscope, key features that can be observed include the cell wall, cell membrane, cytoplasm, and nucleus. These features are labeled for identification based on their distinct shapes, sizes, and locations within the cell.
During the stages of meiosis, under a microscope, you can observe the division of a cell's nucleus into four daughter cells, each with half the number of chromosomes as the original cell. This process involves two rounds of division, resulting in genetic variation and the formation of gametes (sex cells).
Robert Hooke is credited with being the scientist who first observed cells under a microscope. He observed and described cells in a thin slice of cork in his book "Micrographia" published in 1665.
only at the time of cell division in the metaphase and in the anaphase the chromosome are visible. because at this time the chromatin get aggregate and form the thick chromosome which are visible under microscope.

Meiosis was discovered in 1876 by the German biologist Oscar Hertwig. He observed the process of meiosis while studying sea urchin eggs under a microscope.

Cork cells from plants were first observed under a microscope by Robert Hooke.
When observed under a microscope, steel typically appears as a crystalline structure with distinct grain boundaries. The grains can vary in size and shape, depending on the composition and processing of the steel. Additionally, microstructural features such as inclusions, phases, and defects may be visible, providing insights into the material's properties and performance.
