Greg Foot explains the main differences between light and electron microscopes. We need microscopes to study most cells. Microscopes are used to produce magnified images. There are two main types of microscope:. Glass was developed by the Romans in the first century. Since then, scientists have been trying to magnify objects.

Hello, could someone tell me which procedure should I follow to check my sperm count at home? Where can I purchase them? Using a glass slide, which I assume that you have at home if you use the microscope regularly, first you have to examine the volume of the drop collected. This step is crucial, as it will allow you to extrapolate the results obtained by examining the drop to the entire sperm sample. Obviously, you can get much more accurate results if you visit a fertility clinic. Experts use a Mackler chamber at andrology labs to examine the sperm count and motility of sperm samples more easily. Other labs use the the Neubauer chamber, too.

How to check sperm count at home with microscope

Pollen is a powdery substance consisting of pollen grains which are male microgametophytes of seed plants , which produce male gametes sperm cells. Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of coniferous plants. If pollen lands on a compatible pistil or female cone, it germinates , producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail.

A x oil immersion objective is nice to have, but the range of applications are limited. The total magnification of the microscope is calculated by multiplying the magnification of the objectives, with the magnification of the eyepiece which is usually 10x. This range covers most specimens quite well.
