During prophase, chromosomes condense and become visible as distinct structures under a microscope. The nuclear membrane dissolves, and spindle fibers begin to form. The chromosomes appear as tightly coiled structures, preparing for cell division.
Under a microscope, characteristics of filamentous algae that can be observed include long, thread-like structures, cell walls, chloroplasts for photosynthesis, and sometimes reproductive structures like spores or gametes.
Specimens that are transparent and have varying refractive indices, such as biological samples like cells and tissues, can be observed under an interference microscope. The microscope uses the interference of light waves passing through the specimen to create high-contrast images with detailed information about the sample's optical properties.

An example of an organism that can only be seen with a microscope is a single-celled organism like bacteria or protists. These organisms are too small to be visible to the naked eye but can be observed under a microscope due to their size.
Using a light microscope, one can view cell walls, vacuoles, cytoplasm, chloroplasts, nucleus, and cell membranes.

Chromosomes condense and become thicker rod-like structures during the prophase stage of cell division, specifically during prophase I of meiosis and prophase of mitosis. This condensation is necessary for the chromosomes to be visible under a microscope and for proper segregation during cell division.

Movement such as cilia or flagella can be observed under a compound microscope. These are hair-like structures that protrude from certain cells and help with cell motility. By observing these structures, scientists can study how cells move and interact with their environment.

Does what look like what under a micrscope. Everything under a microscope is upside down and backwards. So it would look like a backwards if.
The first microscope used to observe oxygen was the optical microscope, which uses visible light to magnify objects. Oxygen itself cannot be seen under a microscope, but its effects on other substances can be observed. More advanced microscopes like electron microscopes can provide detailed images of oxygen-containing molecules.
Robert Hooke was the first one to discover cells. In 1663 he observed a piece of cork under a simple microscope and noticed that it looked like the cork was divided into "rooms." He called these "cells." Ten years after that, Anton van Leeuwenhoek was the first to observe living cells.
Robert Hooke observed cells in a slice of cork under a microscope, describing them as small, box-like compartments, which he named "cells." This observation contributed to the development of cell theory in biology.
