Anton van Leeuwenhoek
You Must mean White blood cells. White blood cells kill bacteria by first engulfing them, this process i believe is called phagocytocis. They literally eat the bacteria and digest it.
Bacteria can attack and kill cells. White blood cells can kill bacteria.
White blood cells (WBC) of a type called macrophages are attracted to the site of infection and surround the bacteria, digesting and killing them by using hydrogen peroxide created within the WBC.
White blood cells are normal parts of the human body. They are neither viruses nor bacteria.
The white blood cells (also called leukocytes).
We use microscopes to see tiny things like cells, bacteria, and other microorganisms.
Electron microscopes show that animal and plant cells have organelles. The same microscopes show that bacteria do not have organelles.
Can be used to see cells as small as bacteria.
just over 1200 years :)
Antony van Leeuwenhoek (1632-1723) was a Dutch scientist. He designed microscopes that could magnify up to 200 times. These enabled him to discover bacteria, protists, sperm cells, blood cells and many more microscopic features of living cells or micro-organisms. His discoveries were important milestones in the field of biology. He did not invent the microscope, but his inquiring mind, astute observations and his keen mind were all the more impressive as he was not educated as a scientist.

Microscopes improved our lives because some peoples with cancer could die without then. Microscopes helped doctors look at cells and determine cancer cells, so they were easier to remove, when they reproduced. Scientists also used microscopes, and still do because it is easier to see the cells, bacteria, and other microorganisms from the microscope. That is how microscopes improved our lives.
Microscopes powerful enough to see cells weren't invented until the 1980s. These microscpes are called electron microscopes.
White blood cells fight infection while the red blood cells carry blood to your heart.
without it we would not be able to see the cells of plants and animals therefor life and bacteria will still be a mystery.
cells were discovered by an scientist called Anton Van Leeuwenhoek in 1675. he invented a microscope and studied blood, insects and pond water. This lead to discovery of bacteria and cells. Remember that Anton Van Leeuwenhoek named cells.
